对辊式破碎机

Toothed roll crusher, also known as double toothed roll crusher, is mechanical equipment designed for crushing medium and low hardness brittle materials. It is widely used in coal mining, ore processing, metallurgy, aggregate plants and coal preparation plants. It crushes materials such as coal, coke and coal gangue by shear force generated through reverse rotation of double or four toothed rolls. This machine features large crushing ratio, uniform finished particle size and low over-crushing rate.

Feed size: 150-1000mm
Capacity: 100-4000t/h
Suitable For: Coal, Coke, Coal Gangue, Limestone, Shale, Clay, Slag And Other Medium And Low Hardness Brittle Materials
Wide Material Adaptability
Hydraulic Automatic Avoidance Design
Automatic Cleaning Function
Multi-level Safety Protection

We Always Focus On Optimizing The User Experience Of Our Products

1. Wide Material Adaptability

No strict requirement on material moisture content, low energy consumption, and high working efficiency.

2. Hydraulic Automatic Avoidance Design

Effectively avoid damage caused by iron blocks and flexible sundries, ensuring stable operation.

3. Automatic Cleaning Function

Remove adhered materials inside the crushing cavity automatically during idle time.

4. Multi-level Safety Protection

Complete mechanical, electrical, and hydraulic interlock protection safeguards the whole equipment system.

Working Principle

A toothed roll crusher consists of rollers, roller bearings, a pressing device, an adjusting device, and a drive device.

The material is drawn into the gap between the rollers by the rotating motion of the rollers and the friction angle (called the meshing angle) formed between the rollers and the material. As the two rollers rotate, they compress the material into an increasingly smaller gap area, where it is crushed under the compressive force generated by the rotating rollers.

Product Structure

The toothed roll crusher consists of crushing rolls, an adjusting device, a spring safety device, a transmission device, and a frame.
