Product Description

Roll coal crushers is suitable to the industries of coal,  it is more suitable to crush raw coal (included gangue) of big coal mine or coal separating plant. The electrical motor and speed reducer was connected by distance limited hydraulic turbo coupling, which prevents the dynamic overload and sensor overload for safe operation. The distance between the toothed rolls is adjusted by hydraulic and the bearing or the toothed rolls was centralized lubricated. It has the features of optimal designing of gear shape, the choice crushing between tension and cutting, high efficiency with low consumption, uniform production size.

Product Features:

1.Not stuck, low noise, small vibration, less dust, low energy consumption, small space, easy maintenance and so on.

2. With automatic hydraulic pressure  retreating device, which can effectively prevent harm to the normal work of gear.

3.With intelligent cleaning device, it is used to automatically remove the adhesive material on the wall .

4. Adopt machine, electric appliance , hydraulic and other multiple protective devices and linkage device, effectively protect the motor, crusher and the whole system.

5.This product advantages is high efficiency, energy saving, protection environmental .

Working Principle:

Two side belt beltpulley of doble roller coal crusher are drove by motor,make gears are moving opposite , smaller coal  is fall automatically in between the gears,  bigger material is crushed(split, rub off, click) by gear ,  so as to achieve your  required size of particiles.
