Sandvik

Jaw Crushers
 At Sandvik we have over a century of experience of designing and
manufacturing jaw crushers. We also have a wealth of knowledge
about customers’ expectations and needs. This background has led to
the current range of Sandvik jaw crushers which includes models
specially suited for mobile applications. Strength has been increased
and weight has been reduced. Sandvik’s jaw crushers provide an
excellent choice when high production and low total cost are sought.

Robust
construction
The Sandvik jaw crusher is a single toggle jaw crusher, characterized
by attention to detail, in both design and manufacture. We have
incorporated the best of the old and applied the benefits of the latest
technology.
The frame consists of two side plates of rolled steel,
plus hollow castings at front frame end and moving jaw
which give a high rigidity/weight ratio. Large-radius
transition areas reduce stress concentrations and welds
are positioned in low-stress areas. The advantage
of a welded frame is that it is equally strong in all
directions and ensures excellent durability against
shock-loads. Thus minimizing the risk of failure on
the main-frame, as with a bolted construction.
The picture shows an FEA print-out of the predicted
stress distribution in a side plate.

Optimized
performance
● High capacity
● High reduction

● Low jaw plate wear

● Large feed acceptance capability

These four factors are closely linked and the Sandvik jaw crusher
provides a good balance.
The design of the deep symmetrical crushing chamber maxi-
mizes feed size, capacity and reduction.
An optimized nip angle ensures that the material progresses
smoothly down through the crushing chamber to enable high
reduction, productivity and superb utilization of jaw plates.
It is not just a large nominal feed opening that is necessary –
the feed acceptance capability depends on a feed opening which is
effective and active (see illustration).
All crushers in the range have an almost square feed opening so
that they can accept the largest material lumps without blockages.
A thick, replaceable deflector plate protects the top of the
moving jaw from the impact of the feed material. Large material
lumps entering the crusher fall straight into the active region of the
crushing chamber, so there is no need for a stationary cross-wall in
the feed area.

Performance in all types

of application
Sandvik’s wear parts are designed to give high per-
formance and low operating costs. High quality
material and experienced design ensure quality parts.
Fine tuning in applications are ensured through the CC:Coarse Corrugated
available range of alternative jaw plate designs.
All jaw plates are reversible. The “WT” jaw
plate can also be used on both the stationary and ST: Sharp Toothed
moving jaw.

Maintenance friendly
features
Thanks to carefully detailed design, Sandvik’s jaw
crushers secure trouble-free operation and increased
uptime.
● Bearings are grease-lubricated and have grease-
filled labyrinth seals to prevent the entry of dust.
C: Corrugated
HD: Heavy Duty
● Grease lubrication hoses as standard with a cen-
tral distribution block offer safety value and
makes it easier for the operator to grease the
bearings.
● Automatic lubrication system that can be con-
nected to existing control systems for remote
alarm indication. This ensures the protection of
the roller bearings.
● Setting adjustment made with traditional shim
plates.
● Quick and easy installation of jaw plates by using
clamping and support bars to fix the jaw plates to
the crusher.
● Sacrificial parts to protect the main components
of the crusher such as frame, swing jaw and
bearings. This reduces total life-cycle costs and
increases uptime, as it is less expensive to change
the sacrificial parts than the main components.

The capacity figures given in the table above are approximate and are intended only to give an indication of what the crushers can be expected to produce. They apply
for the open-circuit crushing of dry blasted granite with a bulk density of 1600 kg/m3 (100 ibs/ft3) and a maximum size which can be fed into the crushing chamber
without difficulty. The lower values apply for a feed from which the material finer than the crusher’s CSS has been removed. The higher values apply for a feed which
includes the fine material. The minimum CSS at which the crusher can be operated depends on the feed size distribution, the material’s crushability (Wi), the degree of
contamination and moisture in the feed, the type of jaw plates fitted and the condition of the manganese.
