High-Quality Double roller crusher for coarse and fine crushing Manufacturer, Pricelist

The double roller crusher squeezes and grinds materials with two rollers rotating in opposite directions. The structure includes rollers, drive and adjustment devices, and is suitable for coarse or medium crushing of low-hardness materials such as coal and ore. When the machine is working, the material enters the gap between the two rollers and is crushed before being discharged. The particle size of the material can be controlled by adjusting the roller spacing. It has the characteristics of simple structure, low energy consumption, and uniform product particle size, and is widely used in mining, building materials and other industries.

Product Description

Working principle

When the double roller crusher is working, the motor drives two parallel rollers to rotate towards each other, and the material enters the gap between the two rollers from the top. Under the friction and extrusion force generated by the rotation of the rollers, the material is drawn in and crushed under pressure.

When the crushed material is smaller than the distance between the rollers, it is discharged from the discharge port below. By adjusting the distance between the two rollers, the particle size of the discharged material can be controlled.

Frequently Asked Questions

How does a double roller crusher break materials?

It uses two parallel rollers rotating in opposite directions. Materials fed from the top are drawn into the gap and crushed by the combined action of friction and extrusion forces.

Can you adjust the output particle size?

Yes, the final particle size of the discharged material can be easily controlled by adjusting the spacing distance between the two parallel rollers.

What drives the movement of the rollers?

The rotation of the two parallel rollers is powered by a high-efficiency electric motor, ensuring steady and consistent crushing force.

Where does the crushed material discharge?

Once the materials are crushed to a size smaller than the gap between the rollers, they are automatically discharged through the bottom outlet.

What are the key crushing forces utilized?

The double roller crusher mainly relies on friction to pull the materials into the crushing chamber and intense extrusion pressure to crush them.
