The roller crusher mainly consists of the following parts:
-
roller : Two cylindrical rollers (one fixed roller, one adjustable roller) installed in parallel, usually with toothed, grooved or smooth designs on the surface, made of high manganese steel or other wear-resistant materials.
-
Transmission : The motor drives the roller to rotate in reverse through a pulley or reducer.
-
Adjustment device : Control the discharge granularity by adjusting the gap between the two rollers (wedge block or hydraulic device).
-
Spring safety device : Automatically separate the rollers when overloaded to prevent equipment damage.
-
Mining industry : Crushing coal, iron ore, gold ore, etc.
-
Building materials industry : Crushing limestone, gypsum, slag, etc.
-
Chemical industry : Processing of brittle materials such as fertilizer raw materials and coke.
-
other : Breaking of glass and ceramic raw materials.

Key points for selection :
-
Select the roller surface type (toothed/smooth) according to the material hardness, humidity, and particle size requirements.
-
Match roller diameter and speed according to production capacity needs.
-
Pay attention to the compatibility of the motor power and equipment load.
-
-
Maintenance recommendations :
-
Regularly check the wear of the roller surface and repair or replace it in time.
-
Keep bearings lubricated and avoid high temperature operation.
-
Adjust spring pressure to ensure sensitive overload protection.
-
-
The material enters between the two rollers through the feeding port.
-
The two rollers rotate in opposite directions and use friction to bring the material into the crushing cavity.
-
The material is crushed under the squeezing, shearing and splitting action of the rollers.
-
The crushed material is discharged from the gap between the two rollers, and the discharge particle size is determined by the gap between the rollers.
-
Simple structure and low maintenance cost.
-
The discharge particle size is uniform (usually the adjustable range is 2-10mm).
-
Overload protection function to avoid equipment damage.
-
Suitable for fine crushing of medium and low hardness materials.
