ii. Working Principle

This machine consists of two rotors opposite in rotary direction to which several
paddles with special angle are welded. Paddles, on one hand, driver materials to rotate
counter-clockwise along the inside wall of machine groove, on the other hand drive
materials to turn left and right. A weightless zone is formed in the cross and
overlapping place of two rotors. Despite of shape, size and density of materials,
materials can float up and is in a condition of instantaneous weightlessness within this
zone. From then on, materials turn continuously and circularly, and shear mutually
and crossly within the machine groove, thus reaching a quick gentle and even mixing
effect.(See Figure Two and Three)

Figure Three: Figure of Mixing Area

IV. Structure
This machine has a structure of horizontal shell, double spindles and several paddles.
The mixer body is w-shaped and has a spraying and liquid-adding device on the top
where materials are feed. After mixing, materials are discharged from the bottom.
i. Rotors
Rotor consists of paddles, shaft and supporting bar. The motor drives rotor to turn in a
definite speed through reducer and chain. The paddles installed on the dual shaft in a
definite angle cast the materials to whole spaces in the container. In the condition of
instantaneous weightless, materials cross widely to from a flowing layer for mixing,
meanwhile, materials are driven by paddles to turn axially and radically, thus forming
a full-position compound circulation.
ii. Body Machine
The machine body is w-shaped. Each of the two ends of machine body has inside and

6
outside wall plate, between which the space is interlinked to the whole machine body.
While feeding and discharging, air exhausted by materials can circulate in this space
so as not to flow over the machine body.
iii. Sealing Device
The discharging door consists of door body, supporting arm and adjusting nut. Seals
are installed around the discharging door frame. When the door is closed tightly, the
sides of discharging door stick closely to the rubber seal stripe of seal so that
materials in the machine won’t leak. The damaged seal stripe can be replaced. If
necessary, the position of adjusting nut can be adjusted to change the distance
between supporting arm and door body so that discharging door is on level with round
curve surface of the machine shell bottom. The supporting arm is installed on the
coupling spindle.
iv. Discharge Control
The discharging control mechanism consists of cylinder connecting rod mechanism,
coupling spindle and limit switch. The discharging door is installed on the coupling
spindle, the latter is connected to the driven rock rod of connecting rod mechanism,
and cylinder head articulates the driving rock rod. Cylinder moves reciprocally and
drives the coupling spindle to turn through connecting rod, thus driving the
discharging door to open or close.
v. Liquid-adding Pipe
The liquid-adding pipe is installed on the top of machine body and consists of pipe
and spray nozzle. Liquid is sprayed in the shape of fan through the spray nozzle. The
machine body is distributed evenly with several spray head. The entrance end of pipe
is equipped with a flange which is connected to the oil-supplying system.

V. Installation and Adjustment
i. Full check should be made before installing the equipment.
ii. This machine discharges through a big open-door, the connecting port of discharge
is the flange edge of machine shell. A hopper with equivalent volume should be
installed under the machine body.
iii. Install the driving chain, adjust the position of tension chain wheel to make chain
drive smoothly and make main shaft rotate on the direction of arrow shown on the
mixer shell, then install the chain cover. (See Figure Eight)
iv. Install the liquid-adding system.
v. Before use, check to see if discharging door is open or close. Ajust cylinder
pressure and the position of limit switch so that discharging door is on a level with the
bottom of machine shell when it is close, and reach a definite angle when it is open,
and cylinder runs smoothly with a proper speed.

VI. Operation Attention

i. Before use, race the machine, the machine body should be smooth without
abnormal vibration. And observe if discharging mechanism operates normally.
ii. When it use, start the reducer motor and do not feed until rotor turns normally.
iii. Additives should be added after half batch of main materials enters the machine.
After spraying, do not feed before some time of mixing.
iv. When in stoppage and laid aside, oil-adding pipe must not remain oil to prevent oil
from blocking the pipe after solidifying.
v. Materials must not be mixed with metal impurity to avoid damaging the rotor
paddles.
vi. The use of reducer motor and cylinder, Auxiliary components should be consistent
with the stipulations of operation manual.

11
VII. Maintenance
i. The discharging mechanism should keep flexible and it’s accumulated dust should
be often cleared away.
ii. Periodically replace the lube for all bearings. Sodium radical lube (GB492-65)
Zn-3 is a good choice.
iii. The driving chain should be lubricated with appropriate #30 machine oil and
cleaned periodically.
iv. The lube (LD-2H) is recommend for lubricating the reducer motor.
v. Lube should be changed once every eight months continuous run (8 hours work
system). If the work time is prolonged, the oil change time can be properly shortened.

VIII. Trouble Shoot

i. It a sudden machine stoppage occurs during the operation, motor should be started
after the discharging door is opened and material is discharged.
ii. If the discharging door leaks, check the contact of seals between the discharging
door and machine shell. If the discharging door is not closed tight or sealing stripe
ages, limit switch or the adjusting nuts of the supporting arm should be adjusted or the
sealing stripe should be replaced.
iii. If the discharging mechanism cannot work normally, check if cylinder and air
supplying system are in trouble.

X. Pneumatic Control
i. Working Principle (See Figure Nine)

12
1. Use the air compress with 0.7-0.8Mpa rated working pressure. Its produced
compressed air is the power source, ensuring the working pressure of cylinder is
0.63Mpa.
2. Connect the air source pipe and check if pipes are reliably connected. Injected
appropriate lubricating oil into sprayer 7 in accordance with the stipulations
3. Before air is inducted, turn the reducing valve hand wheel 10 counter-clockwise
to inload the rating spring of this valve, then open the air source and turn the
hand-wheel clockwise, thus pressure rises gradually until the pressure shown on the
pressure gauge is the needed working pressure. At this moment, lock hand-wheel
through stop knob 11 to make the system work under the working pressure.
4. If without load and under the working pressure, use the manual 2-position 5-way
solenoid change valve to make cylinder one operate through the manual switch 4, and
check it cylinder and air supplying system are normal.
5. If with load, first adjust the openness of one-way through knob 5 to adjust the
flow to make cylinder piston adjust speed in a wider speed range.
6. If with normal load, solenoid valve is electrified and receives the electric signal
or air signal to change the flow direction of the compressed air and drive the cylinder
to operate, thus realizing the automatic control of air pressure driving.
7. Regularly check the oil level and water level in sprayer 7 and moisture
separator 8 when oil level is near the lowest oil level, oil should be added in time.
Select oil in the range of 2.5-7 F viscosity. When water level is near the filter core 9,
water should be drawn off. When water will be completely drawn off, shut the drain
valve at once.
ii. Maintenance
1. Periodically clean the discharging control mechanism of the accumulated dust.
2. Periodically clean the filter core, water filter and oil filter.
3. All the disassembled parts should be handled with care to avoid damage.
iii. Periodical Disassembly Checking and Points for Attention when Assembling

13
Again.
1. Clean with mineral oil for metal parts, with Soap liquid for rubber parts. Oil filler
and water filler should be soaked in the petroleum solution for rinsing. Never use the
solutions of acetone, ethyl acetate and toluene.
2. All the disassembled parts should be handled with care to avoid damage.
