Roller Crusher

Roller Crusher

Capacity: 1-190TPH
Feeding Size: ≤800mm
Discharging Size: 2-150mm
Handling Materials: Limestone, slag, coke, coal, etc.

A roll crusher crushes materials (coal, limestone, clay) between two rotating rollers. It produces uniform particle sizes with minimal fines, ideal for primary or secondary crushing. Features include adjustable gap control, low energy consumption, and compact design. Suitable for medium-hard to hard materials, but not for sticky or wet feed.

Advantages

01.

Uniform Sizing

Produces even particle distribution with minimal fines, ideal for precise material specifications.

02.

Low Fines

Minimizes over-crushing, reducing unwanted dust and fine particles in final product.

03.

Energy Efficient

Consumes less power compared to other crushers for similar reduction ratios.

04.

Compact Design

Space-saving structure with simple operation, easy to install and maintain.

How Does A Roller Crusher Work

1. Material Feeding: Raw materials enter the crushing chamber through the feed hopper, guided between two parallel rotating rollers.

2. Compression Crushing: s the rollers rotate inward (counter-current), materials are compressed and fractured by high-pressure forces in the nip zone.

3. Size Control: Adjustable roller gap determines output size; particles smaller than the gap fall through, while larger pieces undergo repeated crushing.

4.Discharge: Crushed material exits downward, with optional screens for further grading. Smooth/toothed rollers cater to different material types (coal/rock/ore).
