Application and prospect of double roll crusher, advantages of double roll crusher in ore crushing

Short Description:

The working principle of the double-roll crusher is to use the relative rotation between the two rollers to clamp the material entering the crusher between the two rollers, and crush the material through the squeezing and shearing action of the rollers. The particle size of the material can be controlled by adjusting the gap between the two rollers. When the material enters the crushing chamber, the large pieces of material are clamped and crushed by the rollers, and the small pieces of material are discharged through the lower part of the crushing chamber.

Working principle

Double-roll crusher uses extrusion force and shear force to crush materials through the relative rotation of two parallel crushing rollers. The material enters the crushing chamber from the feed port, is squeezed and ground between the two rollers, and is crushed into the required particle size and discharged from the discharge port.

Structural features

Crushing roller: The core component of the double-roll crusher, usually made of wear-resistant materials to increase service life. The roller surface can be smooth, grooved or with teeth to adapt to different materials and crushing requirements.

Adjustment device: By adjusting the gap between the crushing rollers, the size of the discharge particle size can be controlled. Common adjustment methods include wedge devices and hydraulic devices.

Driving device: Usually composed of a motor, a reducer and a coupling, the rollers are driven to rotate through a transmission device.

Protection device: Including overload protection device and safety protection device. When hard objects enter the crushing chamber or the equipment is overloaded, the protective device can effectively prevent equipment damage.

Main application

In the coal industry： the double-roll crusher is used for the crushing of raw coal. It can not only crush coal but also crush impurities in it, thereby improving the purity and utilization rate of coal.
In the building materials industry： the double-roll crusher is used for the crushing of materials such as limestone and slag to provide suitable raw materials for cement production.

Use and maintenance

Regular inspection: Regularly check the wear of the crushing rollers, bearings, transmission devices and other components, and replace the worn parts in time.
Lubrication and maintenance: Add lubricating oil to each lubrication point on time to keep the lubrication system clean and unobstructed.
Cleaning and maintenance: Regularly clean the dust and debris inside and around the crusher to keep the equipment clean.
Operating specifications: Operate the crusher in accordance with the requirements of the equipment manual to avoid overload operation and hard objects entering the crushing chamber.
