How does the roller crusher work?

A roller crusher works by compressing materials between two parallel cylindrical rollers. The rollers rotate in opposite directions to each other and crush the materials with a combination of compression and shear forces.

Here is the working principle of a roller crusher:

1. Material enters the crusher: Material enters the crusher through the feed hopper and is dropped onto the top of the rollers.

2. Rollers rotate: The two rollers rotate in opposite directions, causing the material to be drawn between them. As the rollers rotate, they exert pressure on the material and crush it.

3. Discharge: Crushed material falls out of the bottom of the crusher and is collected in a discharge chute. The size of the material can be adjusted by changing the gap between the rollers.

4. Repeat process: The process continues as more material is fed into the crusher and is crushed by the rotating rollers.

The advantages of a roller crusher include its low energy consumption, compact design, and ability to handle a wide range of materials. The roller crusher is commonly used in industries such as mining, construction materials, and chemical engineering.
