3.2 LEVELLING THE MACHINE.


This is a smaller and lightweight machine and is mounted on fixed type antivibration pads. When the
machine is positioned, it must be set level. Usually the machine does not require any adjustment for
leveling. However, if required, packing of suitable thickness can be inserted between the antivibration
pads and machine base plate after unscrewing the Allen bolts fixing the antivibration pads to the base
plate.

4. CLEANING A NEW MACHINE.


For protection during transit, all unpainted parts within the turret zone are treated with anti corrosive
coating. This should be thoroughly cleaned off using a solvent such as paraffin.

To obtain access for cleaning, it is necessary to remove the feed frame assembly, hopper, and guard for
turret and tablet chute.

4.1 REMOVAL OF THE HOPPER & FEED FRAME.


For removal of hopper, it is necessary to loosen the locking knob. After that, the hopper can be lifted up
at the top.

Each segment of the guard is secured by locking knobs. The segments are marked with numbers so
that they can be refitted in their correct position. Each guard segment can be pulled out outward after
unscrewing the locking knobs.
After removing the parts mentioned above, clean the turret die bores, punch guide holes, die table as
well as tipper cam track, lower cam track and dozer assembly thoroughly with suitable liquid cleaner
(preferably alcohol). Also clean all the parts, which are removed from the machine. Please refer chapter
“Cleaning” for detailed instructions.

Now fit punches and dies as detailed in chapter “Punches and Dies”. Then refix the parts which were
removed from the machine.

5. MACHINE LUBRICATION.
As lubrication plays an important role in smooth working as well as extended life of the machine, the
instruction for the lubrication must be followed particularly. The correct application of suitable
lubrication contributes considerably towards obtaining high performance and reliability. It is most
important to use correct grade of oil or grease of their equivalent, of any other reputed make. We,
therefore, recommended customers to follow the under mentioned general instructions and
lubrication chart.

1. Slide ways should always be kept free from dirt and dust. The lubrication points of the machine
should be kept clean to avoid lubrication. Lids and covers should be closed properly after grease
and oil application.
2. Anti- friction bearing should only be filled up to 1/3 of the free space Excessive lubrication of fast
running bearing may cause increase of bearing temperature.

IMPORTANT
Only recommended lubricants or their equivalent should be used.
REMEMBER OIL IS CHEAPER THAN SPARES

5.1 MAIN GEARBOX.


This is located within the lower cabinet. Access to the filler and oil sight glass is obtained by opening
the R.H. panel.

When topping up or refilling the gearbox, care should be taken not to overfull, as this can result in over
pressurizing oil seals.

If circumstances permit, it is preferable to run the machine under gradually increasing loads, attaining
full after 30-40 hours running.

Thereafter only normal attention is necessary to maintain correct oil level.

Type of Oil: Refer to lubricants chart.

Note: Lubricants with strong E.P. additives are not recommended for worm gearing.

5.2 LUBRICATION OF FULCRUM PINS AND LOWER ROLL CARRIER FORK PINS.
All the pins are filled with out nipple. They can be lubricated through oil nipple by applying one or two
shot of oil gun.

5.3 OIL DRIP TRAY.


Drip tray with felt wiper is fitted to lower roll carrier. It is filled with oil. The wiper in the drip tray
lubricates the circumference of the lower roll which in turn lubricates the crown of the lower punch
heads.

Fill the drip tray after installation of the new machine and then at regular intervals as required.
Type of Oil: Refer to the lubricants chart.

5.4 LUBRICATION OF TOOLINGS.


CAUTION:
1. 1 Thorough cleaning of the tools is a must before lubrication.
2. 2 Only recommended lubricants or their equivalent should be used. Named oils in this list will be
used in the following instructions.
a. Very lightly smear Enklo-68 or food grade oil on punch body and also the diameter of the
dies at the time of die fitting.
b. Smear sparingly Enklo-68 oil on the lower punch bodies. Also apply little amount of
grease to punch heads and cam running surface.
3. The upper punch head is lubricated by oil from an oil cup through felt pad.

5.4.1 STORAGE OF TOOLING


Toolings are expensive and precise. So they must be stored carefully in wooden boxes to avoid any
damage. Before storing the tools when they are not in use, clean them thoroughly with alcohol or other
suitable solvent, dry them, and then apply lubricant oil to the punches and dies to prevent rusting.

moving parts are free. Access to hand wheel is obtained by opening L.H. panel.

MAKE SURE THAT NO PUNCHES HAVE BEEN FITTED IN TURRET.


Switch on the mains. Then start the main motor by pressing green push button.

The direction of rotation of hand wheel should be anti-clockwise, as indicated by the direction arrow.
The correct direction of rotation of turret is clockwise, when viewed from top.

Our turret drive motor is equipped with frequency converter so it has got self intelligence for direction.
It is only to confirm the direction of rotation of motor.

7. CHECKING THE MACHINE CONTROLS


Checking the machine controls after connecting services

7.1 MACHINE HAND WHEEL


The hand wheel is located within the lower cabinet. It is accessed by opening the L.H. guard.

Anti-clockwise rotation of hand wheel rotates the turret in the correct direction.

WARNING: the machine must not be rotated backwards when punches are fitted in the turret,
otherwise punches and cams may be damaged.

7.2 STARTING AND STOPPING THE MACHINE.


The control panel consists of an isolator switch, speed - regulating knob, “ON” push button, emergency
stop button, and digital counter.

Ensure all guards are properly closed. Turn the electric switch to the “ON” position.
To start the machine, press the green push button on the main control console.
To stop the machine, press the emergency stop button. This button will remain locked in off position
until it is released by turning in clockwise direction.

7.3. MACHINE SPEED ADJUSTMENT


The speed of the machine is regulated by rotating the knob at the control panel. Always start the
machine at low speed initially and increase the speed gradually. The speed of the machine can be
regulated even when the machine is running.

Phone: +91-288-2675560 Fax: +91-288-2556844 E-mail: mail@dynamiceximcorp.com Website: www.dynamiceximcorp.com
Machine Instruction Manual
There is a knob type switch for mode selection of digital counter. The digital counter indicated total
number of tablets compressed, output in tablets per minute or turret r.p.m. as per selection mode. The
digital counter operates, only when the turret is fitted with punches. It should be noted that the
indicator will show the correct speed at the interval of about 1-minute after the adjustment is made.
Also, a key switch for resetting is provided. When the key switch is rotated to reset position, the values,
in memory are erased. Then It starts recounting from zero, after the switch is rotated by 900 clockwise.
Also note that, if all punches are not fitted, the tablet counter will not show the correct figher.

8. SETTING UP THE MACHINE


8.1 TOP PUNCH ENTRYCONTROL
This allows selection of the position within the die where the tablet is compressed and is measured
from the die top face to the lower edge of the upper punch tip.

The upper punch penetration should be predetermined initially. Unless experience shows that a
particular type of tablet can be best produced using is specific top punch entry value, it is advised that
minimum penetration should be used.

The minimum upper punch penetration is useful for easy air escape from the material in die. Proper
selection of upper punch penetration reduces the ejection loads and can extend the working fife of the
die.
The amount of punch entry is varied by, rotating the adjusting knob, at the machine top after loosening
the lock nut. The clockwise rotation of knob increases the penetration. The penetration range is from 2
to 6 mm.

Usually the setting of upper punch penetration should be predetermined before commencement of
making tablets. Do not alter the punch penetration whilst the machine is running.

After setting upper punch penetration, reset the lower roll carrier so that a minimum gap of 0.015” is
maintained between the upper and lower punch tips.

8.2 TABLET THICKNESS CONTROL


The tablet thickness is controlled by adjusting the lower press roll so that lower punch tip positions also
change in die accordingly.

The tablet thickness setting must be done only when the system has some initial overload release
pressure.

The tablet thickness control can be adjusted by opening rear panel of lower cabinet. Rotating hand
wheel from left to right (anti-clockwise) will increase tablet thickness and vice versa.

Phone: +91-288-2675560 Fax: +91-288-2556844 E-mail: mail@dynamiceximcorp.com Website: www.dynamiceximcorp.com
Machine Instruction Manual
Tablet thickness can be adjusted while the machine is running. Always reduce the depth of fill first, at
the time of decreasing the tablet thickness, to avoid overloading.

IMPORTANT:
Before fitting punches ensure that the tablet thickness is set to maximum i.e. the lower roll is in its
lowest position. Failure to do this could result in damage to the upper and lower punch tips.

The reason for this procedure is that whilst turret is being rotated, without tabletting material in the
dies, it is possible for the upper and lower punch tips to come into contact at the compression position,
unless the lower punch is fully lowered.

8.3 TAMPING TABLET THICKNESS CONTROL


The purpose of the pre-pressure is to deaerate the die filling & thereby shorten the main press
operation, which can lead to a considerable increase in the productivity of the machine; this effect is
brought about by the expenditure of relatively little pre- pressure energy.
Too high a pre-pressure brings no such commensurate improvement in the machine productivity, but
on the contrary, produces more noise & wear. It is recommended to apply the following principles
when making adjustments.

8.4 UPPER TAMPING ROLL ADJUSTMENT


Before setting the upper tamping roll position, first set the main upper punch entry. The penetration of
the punches which is adjusted by the upper pre-pressure roller should be the same as, or apprpx.
Between 0.5 to 1mm smaller than the penetration adjusted by the main upper pressure roll.

The upper tamping roll can be adjusted by loosening the clamping bolt at block for upper p.c. roll pin &
rotating the eccentric tamping roll pin by handle. The block for Upper p.c. roll pin is marked with
graduations to indicate punch tip position from the top of the die.

8.5 LOWER TAMPING ROLL ADJUSTMENT


After fixing the upper tamping roll position, minimize the pre-pressure by turning the Knob until the
upper pre-pressure roller no longer turns while the machine operates.

Now start and set the machine for required tablet parameters. After setting run the machine
continuously. Turn the Knob slowly until the upper tamping roll turns fully with the machine. Normally
the lower tamping roll is adjusted to get tamping tablet thickness approximately 3mm more than the
final tablet thickness. The clockwise rotation of the Knob is results in decrease in tamping tablet
thickness.

Machine Instruction Manual
8.6 WEIGHT ADJUSTMENT
Both the Layer Tablet weight can be controlled by adjusting the dozer position. The dozer and wedge
can be adjusted vertically by rotating the adjusting knob. Anti-clockwise rotation of the knob increases
tablet thickness, whereas clockwise rotation decrease tablet weight.

The adjusting knob of First layer is located at Right side of lower cabinet,& For Second layer Left side of
Lower cabinet.

Note: To maintain accurate weight control, it is essential that the lower punch brake plugs are fitted
and working correctly.

8.7 FIRST LAYER TABLET SAMPLING DEVICE


This is a manual operating device to take first layer sampling tablet through Discharging chute located
on left side on machine. To operate this device simply rotates Knob anticlockwise of sampling assembly.
Once you rotate the knob the rack moves up side & through wedge at Sampling boss the Lower punch
takeout sampling tablet. Through Tablet scraper tablet discharge in discharging chute.

8.8 SAFETY OVERLOAD PRESSURE SETTING.


Before commencing to make tablets, check the “maximum punch load” chart against the diameter and
tip of the punches fitted, to the machine. Using the overload adjusting wheel set appropriate load in
the machine.

When the machine has finally been set up and is producing the required both the layer tablets with
respect to all parameters, set the safety overload pressure as under:

After the machine has been set and able to produce required tablets for both the layer, reduce overload
release pressure until an overload condition just occurs. This can be observed by movement of lower
roll carrier. Increase the pressure until the overload condition ceases and increases the pressure further
by one more turn of the adjusting wheel. Always make this setting, while the machine is running.

The safety overload system will then will then give the maximum protection to the machine as well as
punches for particular tablets being compressed.

WARNING:
UNDER NO CIRCUMSTANCES MUST THE MACHINE BE RUN IN A CONTINUOUS OVERLOAD CONDITION,
OTHERWISE THE MACHINE AND PUNCHES WILL SUFFER MECHANICAL DAMAGE.

Note: Unless the machine is in an overload condition, increasing the overload pressure will not effect
the hardness of the tablets.

8.9 SETTING EJECTING HEIGHT OF FINAL TABLET


When the machine leaves the factory, the ejection cam is set according to standard 5.262 long punches.

If shorter or re-faced lower punches are to be used it is necessary to adjust the height of the ejection
cam accordingly. The adjustment is achieved by inserting shims under ejection can.

When set correctly, the punch tip should be perfectly level with die table at the point of ejection.
Generally for normal tablets the punch tip should be flush with the die table surface. However, for
tablets having more cup depth, the punch tip may protrude above the die table depending upon the
requirement.

If the height of the ejection to the cam platform by an Allen bolt. To access this remove the turret
guards.

Machine Instruction Manual
The ejection cam is secured to the cam platform by an Allen bolt. To access this remove the turret
guards.

This work must be carried out before the lower punches are fitted.

8.10 LEVELLING THE FEEDER PLATFORM


It is important that the feeder platform is set correctly before fitting feed frame to it.

The feeder platform is correctly set during the building of the machine and need not be leveled.

The platform level should be checked at regular intervals. This is done by placing a parallel ground bar
about 1” square and 8” long or the platform. Check that the surface of the platform is perfectly parallel
with the die table. The height of the platform must be 0.12 mm (0.005”) higher than the die table. Use
filer guage to check this. If any deviation is found, adjust the platform by inserting, packing’s between
support pillar and feeder platform.

CAUTION:
If the clearance between the feeder platform and die table is more, there will more spillage of material
from the space between the feed frame and die table. If the clearance is less, the bottom, surface of the
feed frame may be damaged.

Note: The feeder platform should not be disturbed for cleaning operations or other simple work and
should only be removed to allow major maintenance work.

8.11 TABLET MATERIAL FLOW ADJUSTMENT


The hoppers fits on the spindle and can be adjusted vertically by means of the hopper height adjusting
knob after loosening the locking knob to control the flow of powder from the hopper into the first
compartment of the feed frame. A small laterai adjustment can also be made, which has a marked
effect upon the flow of powder. The most suitable position for the hopper can only be determined by
experiment and is dependent on the type of material being compressed, the size of the tablets being
produced and speed of the machine. The flow of material should be sufficient to allow for a return flow
material to the front of the feed frame for re-circulation.

Note: It is important that the input of material only, slightly exceed the amount being consumed to
make tablets. This prevents the excess, material front held too long in the feeder and the characteristics
of the granules altered by pulverization, thus altering the quality of the tablet.

9. PUNCHES AND DIES
The production of good tablets depends finally on good punches and dies and these must be (1)
Accurate in dimensions (2) Correctly hardened, and (3) Perfectly finished.
The clearance between punch tip and die bore should be such that punch is not too tight in the die or
too big clearance for powder to get down.
The life of moving parts can be considerably lengthened by the skill and care given to the finish of
toolings.
We therefore recommend to use punches and dies made by only, reputed manufactures.

9.1 FITTING OF PUNCHES AND DIES.


Before fitting or removal of punches and dies, first isolate the electric supply to the machine. It is also
necessary to remove various items from the machine, i.e. hopper, feed frame assembly.
Remove the powder from the turret zone. Clean the machine. Please refer chapter “Cleaning” for
detailed instructions.

9.1.1 FITTING DIES.


Ensure that the die pockets are thoroughly cleaned. The die should be cleaned and lightly smeared the
outer diameter with Enklo-68 oil, then be placed on the die table of the turret. By pressing the die down
with the fingers, the die can be accurately located in the pocket. It is imperative that the dies must be
driven into the die pocket, perfectly square otherwise die pocket will be damaged. Once the die is
located, the die bar (supplied with the tool kit) should be entered through the upper punch guide hole
and allowed to drop onto the die face three or four times from a height of approximately 3 inches. This
is sufficient force to enter the die in the pocket. After the die is well entered and it is certain it is square
with the die pocket more force can be applied either by increasing the height from which the die bar is
dropped or with blows from a hammer on the die bar until the die is fully down on the seat of the die
pocket.

When the die is fitted correctly, the top face must be perfectly flush with the die table. Failure to do this
will result in damage to the feed frame surface powder scraper blade, etc.

9.1.2 FITTING THE DIE LOCKING SCREWS.


The die locking screws have a curved spigot end and are fitted with a dowel pin to align with the
annular recess in the periphery of the die.
The die screws should be tightly oiled on the thread and fitted into die screw holes with the dowel
located in the keyway of the die screw hole.

IT IS OF THE UTMOST IMPORTANCE THAT NO EXCESSIVE FORCE IS USED IN TIGHTENING THE DIE
SCREWS, ALSO DIE SCREWS SHOULD BE TIGHTENED AFTER MOUNTING ALL THE DIES PERFECTLY.

Machine Instruction Manual
A MAXIMUM LOAD OF 14 LB.FT (194 KG. CM) SHOULD NOT BE EXCEEDED TO PREVENT DISTORTON OF
THE TURRET.

An extension of the special Allen key supplied or a hammer must NOT be used as this can cause the
turret to crack, or distort the die bore.

After tightening the die screw, check that the top face of the - die has remained flush with the die table.
If it should happen that a die rises in the die plate due to escessive tablet ejection loads, no amount of
tightening of the die - screw will prevent this.

Note: Further investigation should be made as to the cause of the excess force.
Assuring the bores are not worn (barreled), it may be possible to reduce ejection loads by adding more
lubricant to the material being compressed or by using dies with specially manufactured tapered bores.

9.1.3 FITTING LOWER PUNCHES INCLUDING PUNCH OLDING DEVICE.


Punch loading plug can be accessed by removing the L.H. lower panel.
Remove the punch loading plug from the middle plate by just pushing it from bottom. The punch
loading plug is lying free in the cavity.

A flywheel is provided to rotate the machine manually specifically for loading and unloading of
punches and dies. This arrangement makes it convenient for one person to fit punches and dies. Rotate
the turret slowly with the help of flywheel so that a punch guide hole coinsides with the punch loading
plug cavity.

Check that the guide bore and punch are clean. Smear the lower punch body with the specified grade
of oil and apply little amount of grease to the head and cam running surface.

Insert the punch into the guide hole. Push the punch to its highest position and ensure it drops freely
under its own weight. Carefully rotate the turret by means of the flywheel until the punch is clear of the
loading port. Fit the remaining punches in the same way.

REMEMBER TO REPLACE THE PUNCH LOADING PLUG AFTER INSERTING ALL THE LOWER PUNCHES.

WARNING: DO NOT START THE MACHINE UNTIL THE PUNCH LOADING PLUG IS PROPERLY POSITIONED.
WHEN LOWER PUNCHES ARE FITTED.

Now enter the brake plug for lower punch into the turret and fix the anti turning spring with the round
head screw.

Machine Instruction Manual
To prevent punch flight and also double embossing of the tablet, friction is applied to the lower punch
body by means of a brake plug, which is tensioned by a leaf spring.

IT IS ESSENTIAL THAT THESE PLUGES ARE FITTED OTHER WISE CONSISTENT TABLET WEIGHT CANNOT BE
MAINTAINED.

The condition of the brake plugs should be periodically examined and if they are worn out and not
capable of restraining the punches, they should be replaced immediately

Tighten the punch holding plugs. After tightening them, lift each punch to make sure the plugs are
capable of retaining the punch in the elevated position.

Rotate the turret at least one full revolution, with the flywheel to ensure the punches run freely through
the cam system.
NEVER ROTATE THE TURRET BACKWARDS AS THIS WILL DAMAGE THE PUNCHES PND CAMS.

9.1.4 FITTING ROUND UPPER PUNCHES.


Ensure the punch guide holes and the punches are clean.
Smear lightly the upper punch body with specified oil and apply a little amount of grease to the punch
head and cam running surface.

Check that each punch is free to move in its guide and capable of dropping under its own weight onto
the cam track.

Note: Care should be taken to ensure that the keyways in upper punch guide holes are thoroughly
cleaned.
Rotate the turret at least one full turn by flywheel to recheck to ensure that the upper punches enter
the die bores without tipping and they run freely throughout the cam system.

9.2 SPECIAL PURPOSE PUNCHES AND DIES.


9.2.1 FITTING SHAPED PUNCHES AND DIES.
Shaped Punches and dies can only be fitted to machines which have a turret with slotted upper punch
guides. The turrets are slotted as standard.
Punches and dies with any shape other than round require very careful fitting. The procedure for
cleaning the punch guide hole and die pocket is the same as when fitting the round punches and dies.
In addition to removing the parts mentioned earlier, the punch take out plate for upper punch must
also be removed.
Thoroughly clean an upper punch and lightly smear the punch body with specified oil and apply little
amount of grease to the punch head and cam running surface. Then place it into the punch guide hole.

Machine Instruction Manual
Make sure that it will work up and down freely without any suspicion of tightness in the keyway. With
the punch still in position, place a die over the punch tip before entering the die into the die pocket in
the die plate. Push the die into the die pocket with the same punch. Remove the upper punch and
drive the die into position in the normal manner. After filling the die, re-enter the punch and check that
it will enter freely into the die for its full depth.

Replace and lightly, tighten the locking screw assembly as a precaution against it standing projected
out of the periphery of the turret, but on no account use force. If the Die should have turned when
being driven in, it will be necessary to drive it out and start again. When assured that free fitting is being
obtained, apply lubricants to lower punch and fit it in usual manner Ensure that the lower punch also
moves freely in the die bore. The remaining punches and dies should be fitted with the same
procedure.

IT IS OF THE UTMOST IMPORATANCE THAT DIE SCREWS SHOULD BE TIGHTENED AFTER MOUNTING ALL
THE DIES PERFECTLY.
It is then advisable to recheck to ensure that all the upper punches enter into the die smoothly without
“tipping” by rotating the turret. Refit the punch, take out plate, check the level of cam running profile
and lock in position with the socket head screw.
Special attention should be given to lubrication when using shaped punches and dies, as they do not
revolve and disperse the lubricant in the same manner as round punches. This particularly applied to
the punch heads and also the cam running surface and they should be well smeared with the
recommended lubricant.

9.3 LUBRICATION OF TOOLINGS


CAUTION:
1. Thorough cleaning of the tools is a must before lubrication.
2. Only recommended lubricants or their equivalent should be used. Named oils in this list will be
used in the following instructions.
(a) Very lightly smear Enklo-68 food grade oil on punch body and also the diameter of the dies at
the time of die fitting.
(b) Smear sparingly Encklo-68 oil on the lower punch bodies. Also apply little amounted of
grease to punch heads and cam running surface.
3. 3 The upper punch head is lubricated by oil from an oil cup through felt pad.

9.4.1 STORAGE OF TOOLING


Toolings are expensive and precise. So they must be stored carefully in wooden boxes to avoid any
damage. Before storing the tools, when they are not in use, clean them thoroughly with alcohol or
other suitable solvent, dry them, and they apply lubricant oil to the punches and dies to prevent
rusting.

10. TWO LAYER TABLET COMPRESSION SYSTEM:
Two layer tablet compression system is enables the machine to be used as first layer sampling tablet
producing & takeout separately & Two layers will be separate on ejection. Two layer tablet compression
system producing high quality two layer tablet with a single outlet.
The machine is built up with facilities for,
1) Hardening first layer prior to weight checking.
2) Adequate provision to prevent cross contamination between the materials of the two layers.
3) Hardening first layer sample take out separately & also at the time of Final tablet.

10.1 PRINCIPLE OF OPRATION FOR LAYER TABLETTING:


The granules for the first layer are fed into the dies by the right hand force feeder, the correct amount is
regaled by the weight adjusting cam, and excess granules are ejected from the die cavity back into the
feeder. The material then passes between the front pressure rolls where the granules are tamped by the
upper and lower punches. The degree of pressure applied should be just sufficient to produce a sharp
demarcation between layers without affecting the bonding of the first and second layer. The degree of
tamping can be regulated by adjusting the lower roll by the tablet thickness control. The lightly
compressed tablet, maintained at a height fixed by the amount of top punch penetration at the first
compression station, passes under the second feeder and receives its second charge of granules. Again
the fill of granules is controlled by the appropriated weight adjusting cam and the surplus granules are
ejected into the left hand force feeder. But it should be noted that the maximum depth of feel is
controlled by amount of upper punch entry at the first compression. The dies, containing the two layer
of material pass between the final compression rolls. Which are the compressed tablet hardness. The
compressed tablet is ejected and deflected down the take off chute (R.H.) The weight of the layers can
be checked whilst the machine is in operation. To affect this lower pressure roll of the first compressing
station is mounted on an eccentric pin, which has a gear cut on one end. This gear meshes with a rack
mounted on the end of an air cylinder piston rod. When a weight check of the first layer is required the
selector switch is put in ‘ON” condition. This actuates the air cylinder, which in turn pushes the rack
upwards, and thus rotates the eccentric pin. The movements of the eccentric pin lift the lower pressure
roll and increase the hardness of the first layer. Due to this increased hardness no bonding between
layers will take place during the final compression and the two layers will separate on ejection.

Weight of the first layer can be obtained by direct weighing the first layer sample and the weight of the
second by subtracting the first layer sample tablet weight from the total weight of the completed two
layer tablet.

10.2 OPEARATING INSTRUCTION FOR TWO LAYER TABLETS:


Fill the hopper feeding the right hand force feeder with the material for the first layer. Set the upper
punch main & pre compression penetration. Start the machine and adjust the first layer weight
adjustment by rotating knob right hand side on machine and set lower pre-compression roll to give a

Machine Instruction Manual
hard tablet of the weight required for the first layer. Having set the weight of the first layer, fill the left
hand hopper with the material for the second layer. Start the machine and adjust the second layer
weight adjustment by rotating knob left hand side on machine and then final tablet thickness control
to produce a final two layer tablet of correct weight and thickness.

At this stage it is advisable to examine the tablet for clear layer demarcation and good cohesion
between the layers.

10.3 LAYER SAMPLING:


When we need two layer tablet of correct weight, hardness and quality fill the required correct weight
of first layer weight adj. & set Lower pre compression roll to make soft tablet of first layer. Now fill
required correct weight of second layer weight adj. & set main roll to make final two layer tablet.

When we need First layer sample tablet, fill the required correct weight of first layer weight adj. from
right side of the machine & than set lower pre compression roll upper than soft tablet position to make
first layer hard tablet. After that second layer weight fill & two layer tablet produced. At this stage first
layer hard tablet easily we can separate from second layer.

When we need only first layer sample tablet, fill required correct weight of first layer weight adj. & set
lower pre-compression roll as per required hardness. Now after that rotate knob of First layer sampling
assembly anticlockwise. Once you rotate the knob the rack moves up side & through wedge at
Sampling boss the Lower punch takeout sampling tablet. Through Tablet scraper tablet discharge in
discharging chute.

10.4 TROUBLE SHOOTING:


I. POOR DEMARCATION LINE
This may be due to the tamping pressure being too light. If it is, the tamping pressure can be
increased by raising the lower roll, slowly, by means of the tablet thickness handle at the front
compression station. The first layer should be re-checked by switching on the air supply. This will
ensure that the machine or the air cylinder controlling the machine has not been subjected to
an overload. If the machine has been overloaded the red light on the control panel would light
up or hissing noise will be heard from the pressure regulator. If either of these warning occur
decrease the hardness layer sampling controlling control until the machine runs smoothly.

Further the reasons for poor demarcation may be the size of granules used, the distribution of
granule sizes, poor lubrication of the granules etc. if the mechanical conditions of compression
appear to be satisfactory the next point to investigate is the granulation.

Machine Instruction Manual
II. POOR COHESION BETWEEN LAYERS
If the two layers do not cohere this may be due to the tamping pressure being too great. To
reduce the tamping pressure, gradually lower the front lower roll increasing the tablet thickness.
Improved coherence between layers should result from this reduction of tamping pressure.

IMPORTANT:
If the customer is interested in two layer tablet compression system for CADPRESS - II machine, it should
be ordered out specifically along with the standard machine.
Note: Before operating the machine for production of two layer tablet it is advisable to refer to the
general instructions for operation and lubrication and standard machine components details. These are
contained in the CADPRESS-ll instruction manual.

11. TABLETING MAKING


11.1 CHECK POINTS BEFORE AND AFTER STARTING THE MACHINE.
(1) The operation of all the machine controls is understood very well.
(2) After fitting the dies, check that they are flush with the die table and the dies are locked
properly with the die lock screws.
(3) Check that punches are free in punch guide and upper punches drop, under their own
weight.
Note: Tight punches cause unnecessary wear on cam track, punch heads and punch
guides.
(4) Check that punches move freely through the cam tracks (upper and lower)
(5) Check lower punch tip position. At the ejection it should be flush with the die table.
(6) Check that lower punch brake plugs (anti turning device) are fitted and working.
(7) Check free rotation of press rolls.
(8) Check that all the necessary parts are properly lubricated.
(9) Check that Feed Frame is mounted correctly.
(10) Check oil levels at main drive gearbox, oil cup, oil drip tray at lower carrier.
(11) Check that all guards are closed.
(12) Check overload, pressure corresponding to the punch tip is set correctly.
(13) Check that scraper blade is flush with the die table.
(14) If tapered dies are fitted, check that they are fitted correctly, i.e. with “U” showing on the
upper side.
(15) Check that upper punch penetration is set correctly.
(16) Always turn machine at least two to three revolution BY HAND before running under
power.
(17) Check that there is material in hopper.
(18) Check that there is clearance between hopper bottom outlets and die table surface.

Machine Instruction Manual
11.2 MAKING TABLETS
(a) Set the initial overload pressure at minimum (approximately 1.5 tons)
(b) Set upper punch penetration as required. It is suggested that 1/8” (3mm) should be used at first
unless high or low punch penetration is decided by previous experience.
(c) Set the tablet thickness to double the thickness of that tablet required.
(d) Set weight adjustment to the estimated value. If any doubt, set at lower side.
(e) Adjust the gap between hopper and the die table to control the flow of material. Normally it is
kept between 2 to 3 mm depending upon the granule size.
(f) Fill hopper with the material to be compressed.
(g) Rotate the turret with the flywheel if necessary, adjust the weight control and tablet thickness
control until tablets are produced with sufficient hardness.
(h) Adjust the speed control knob to the minimum output, before starting the main motor.
(i) Rotate the machine under power, taking sample weights and if required, adjust the weight
control until the correct tablet weight is consistently obtained.
ALWAYS INCREASE THE TABLET THICKNESS PRIOR TO INCREASING THE TABLET WEIGHT TO
AVOID OVERLOADING.
(j) Reduce the tablet thickness control to obtain the required tablet thickness as well as hardness.
(k) Increase the speed to achieve the output required. When the output is increased are decreased
compensating adjustments will have to be made to weight control and material flow from
hopper.
(l) Set the safety overload pressure using the flowing method. After the machine has been set and
able to produce required tablets, reduce the overload release pressure until an overload
condition just occurs. This can be observed by movement of lower roll carrier. Increase the
pressure until the overload condition ceases and increases the pressure further by one more turn
of adjusting hand wheel. Always make this setting while the machine is running.
The safety overload system will then give the maximum protection to the machine as well as
punches for particular tablets being compressed.
