1. Brief introduction

Double-roll crusher is for primary crusher for material. It is mainly suitable for crushing of 

coke, coal, limestone, chalk, and urea and etc.

2. Mode of operation

Four roll crusher is usually used belt conveyor or vibration feeder roller to feed along the 

direction of vibration feeder, two electric motors through two sets of sprocket reducer

, coupling and combination each driving a pair of crushing roller rotation, the broken material 

after broken by upper and low two sets of rollers then discharged from the bottom of the 

device.

one.Structure characteristics

We can select different configuration and additional equipment according to the using 

situations.

three.1 Smooth / groove surface roller

The working surface of crushing roller can choose a smooth or grooved one, smooth roller is 

suitable for crushing medium-hard material, the groove surface roller for brittle or sticky, wet 

and materials need to obtain large crushing ratio.

3.2 Mechanical / hydraulic buffer device

Movable crushing roller equipped with mechanical or hydraulic buffer device, when a foreign 

body into the body the protective effect on the work roll will work, it also can also be used

to adjust the gap of the work roll, to compensate the wear consumption of the roll skin.

3.3 Device for cutting / grinding device

When the roller skin abrasion or appear groove, pit, can directly use cutting device for 

roller refurbishment without detaching roller. When change the material and heat 

treatment process to improve the lifetime of roller skin. To improve hardness, cutting, 

using the patent product of our company in the roller grinding device, grinding roller 

by quartz at the normal speed of grinding wheel greatly reduced the repairing intensity 

of labor. Wheel rotation and take the knife can use electric.

3.4 Flat belt / multi wedge belt drive

Between the driving roller and a driven roller adopts flat belt drive, when belt slippage 

between the upper roll and the lower roll to protect the motor and speed reducer. Pulley

is added between the bigger and smaller belt pulley, which not only can control the belt 

tensioning degree, but also can increase the size of the belt wheel angle, make the 

equipment normally starting, flat belt is not easy to slip. Also can use multi wedge belt 

to drive, when the belt starting the installation is not easy to drop off, and can play the 

role of flat belt.

three.5 Automatic lubrication system

Automatic lubrication system inject amount of grease to reduce friction and wear, 

and has the sealing function for bearing according to the progressive principle. 

3.6 The electric control device

Special power control cabinet, the cabinet body is a closed type, suitable for dusty 

environment, and the assembly conforms to the GB7251.3-97 standard. Rotary handle is 

connected with the power supply air circuit breaker cabinet through the long axis, it do not 

need to open the door to the operation in the outside of the cabinet. For the convenience 

of double speed motor connection transformation, adopts the pentode axis contactor, 

makes the main contact to move coaxially.

3.7 Iron remover

The iron remover should be equipped on the feeding belt in order to ensure the continuous, 

stable operation.
