Double Roller Crusher

The double roll crusher is a mechanical device with a simple structure, high crushing efficiency, and uniform particle size. It is widely used in many industries. However, when selecting and using it, its advantages and disadvantages need to be considered comprehensively according to its own production needs and material characteristics.


A double roll crusher is usually followed by a primary or secondary crusher and is used for secondary and tertiary crushing of various minerals.

Double Roller Crusher of Application

Ore crushing: Roller crushers are used in mining to crush ores of various hardnesses, such as limestone, granite, iron ore, etc. Whether it is an open-pit mine or an underground mine, roll crushers can perform crushing operations well to meet the needs of mining production.

Slag processing: In the metallurgical and chemical industries, roll crushers are often used to crush various slags and chemical raw materials into the required particle size for subsequent smelting or processing.

Working principle

What Is The Working Principle Of The Double Roller Crusher

What is the working principle of the double-roll crusher?


The double-roll crusher performs crushing operations through rollers. The material enters between the rollers from the feed port and is crushed by extrusion. When the roller seats rotate towards each other, the material is rolled between the two rollers under the action of the friction force on the roller surface and its own gravity and is subjected to extrusion, impact, shearing, and kneading from the rollers. When the action of these forces is greater than the aggregation force between the crystal lattices of the object, the material breaks into small pieces and the purpose of crushing is achieved.
