Jaw crushers DCJ and DCD – low costs, high capacity

June 8, 2023 nflg 0 Comments

JAW crushers Feathers

High operating reliability, low costs for operation and maintenance, simple attendance and maintenance.

PSP Engineering supplies jaw crushers that are used mainly for primary crushing of all kinds of aggregate and ore, and building materials such as reinforced concrete, building debris, bricks and asphalt blocks. The jaw crushers are produced according to the type and capacity size ranging from several tons to more than 1000 t/h.

Jaw crushers are advantageous for their excellent operating properties:

High operating reliability, Easily replaceable spare parts, Low operating and maintenance cost, Exceptional degree of comminution, Low specific energy consumption, High capacity, Ideal geometry of the crushing space, Rugged design.

PSP Engineering manufactures the following versions of jaw crushers:

Single-toggle jaw crushers DCJ
DCJ provides a higher degree of comminution, better shape value of grains, lower weight, smaller dimensions.

Double-toggle jaw crushers DCD
DCD is able to crush extremely hard and abrasive materials.

Slot adjustment
The slot is adjusted by adjusting shims that eliminate the jaw crusher wear. Adjustment is easy by means of hydraulic cylinders with
a hand-operated pump. Some selected types are fitted with a comfort hydraulically controlled adjusting wedges.

Hydraulic single-toggle jaw crushers DCJ-H are remote-controlled with an automatically adjusted outlet setting, hydro-pneumatic overload protection and automatic lubrication. This system is virtually an attendance-free system.

Toggle plates
Toggle plates are of a rolling design with a long service life that do not need lubricating, and are non-polluting.

Protection device
Protection device protects the shaft, bearings, pendulum or bed against damage if noncrushable piece occurs in the crushing
chamber. It consists of:
– Breaking plate
– Safety coupling in flywheels.

When non-crushable piece gets into the crushing chamber, the safety coupling arms are released therefore stopping the pendulum
while flywheels rotate freely on the shaft. No parts must be replaced and re-assembly takes just several minutes.

Integrated drive
There are several types of drives integrated in the frame of the crusher saving space and extending the service life of V-belts available.

The frame is rugged and well-welded together as one unit or if the crusher is bigger, it consists of several parts bolted together.

Large-diameter shafts are made of a treated chrome-vanadium forged pieces. Automatic lubrication is available.

High-percentage manganese jaws are reversible, which extends their service life.

Flexible seating of crushers on rubber springs decreases the forces on foundations significantly.
