Product Description

2PGC Roller Crusher Introduction
are used mainly for crushing easily fractured materials such as soft limestone, coal, chalk, and clay to between 1/3 and 1/5 of its original size.

2PGC Roller Crusher is Ideal for
1. Double roll crushers are used for both, primary and secondary crushing. They guarantee a strictly defined final grain size with a minimum of fine grains;
2. Raw materials, secondary materials and by-products such as coke, sinter, coal, soft to medium-hard rock, ore, chalk, broken glass and similar products.

Main Customer Benefits of Double Roller Crusher
1. With the advanced hydraulic control system, users can adjust the pressure according to the material hardness, so that can press and pulverize the materials absolutely;
2. With sensor, the machine can load relief when overload, so that to protect the machine;
3. The advanced hard faced technology improves the roller covers' life;
4. Good performance, low cost in operation and easily maintenance.

The motor drives the fixed roller and movable roller to work via reducer and coupling. Materials are put into the space between the two rollers via the feed entrance. As the two rollers inward turning, the input materials are crushed, pressed, ground, and at last come out from the base of the machine.

2PGC Roller Crusher Features
The crushing rolls consist of the roller bodies, complemented with crushing rings or crushing shells. The rolls are secured either with anchor bolts and end disks, or bolted with screws. In order to facilitate maintenance, the crushing roll shafts are arranged in heavy-duty cast steel housings with lubricated, amply dimensioned spherical roller bearings. Materials used are of highly wear-resistant specially cast alloys in order to achieve long lifetimes of parts.

Changing Operating Conditions Require Adjustments
1. When the crusher has been running for some months or some years, the raw materials may become harder to crush or a higher output may be needed. The MHC Twin shaft breaker can then be adjusted in several ways;
2. The size of the drive pulleys may be altered to achieve a higher throughput or a higher torque;
3. Minor adjustments of the output size can be made by altering the synchronization of the two rotors.
