Description

Introduction: 
Roller crusher is mainly applied in cement, metallurgy, chemical, electric power, coal and other industries for crushing various materials of medium hardness like limestone, slag, coke, coal and other materials. According to the numbers of the roller, it is divided into single roller crusher, double rollers crusher and multirole crusher. It has simple structure, less phenomenon of over-crushing, and reliable operation. 

Features: 
1. Simple structure, reliable operation 
2. Low cost and less over-crushing phenomenon 
3. Adjustable discharging size and high economic benefits 

Principle: 
It mainly consists of frame, rotary device, crushing roller, adjustment device and spring safety device. When working, the two rollers rotate toward each other, and the minerals will enter between them, by action of the friction, the minerals will be sent into the crushing space for pressing. Due to the gravity of minerals, they will be discharged out from the gap of two rollers. And the minimum distance of the two rollers is the width of the discharge size.
