Introduction of roller sand making machine:

Working principle

After the material enters the crushing chamber of the roller sand making machine, it is subjected to the meshing force of the rotating roller shaft and is forced to pass between the two rollers. At the same time, it is squeezed and sheared by the roller shaft and begins to break. The broken small particles are thrown to the bottom of the machine through the gap between the two roller shafts along the tangent of the roller rotation. The large particles exceeding the gap continue to be broken into small particles and discharged.

Structural composition

Roller: It is the main component for crushing. It is cast from 45# cast steel and embedded in the main and auxiliary shafts. The surface can be designed with teeth or smooth.

Adjustment device: A wedge or gasket adjustment device is installed between the two rollers. The gap between the two rollers is adjusted by adjusting the bolt to pull up or lower the wedge, or increase or decrease the number and thickness of the gaskets, so as to control the particle size of the discharge.

Drive device: It is driven by two motors to the groove wheel or shaft through a V-belt or a reducer to drag the rollers and rotate in relative directions.

Frame and body: The frame is welded from steel sections and plays a supporting role; the body is cast from high-quality cast iron, with an upper and lower split structure, cast into a closed box form, the roller is installed in the box, and wear-resistant liners are often installed on both sides of the cover.

Performance characteristics

Good crushing effect: The rotation speed and gap of the rollers can be adjusted, which can achieve the crushing and refinement of different materials and improve production efficiency.

Uniform crushing: The gap between the rollers is uniform, the material is subjected to uniform force, and the crushing effect is uniform.

Low energy consumption: Advanced transmission devices and energy-saving motors are used to reduce energy consumption.

Adjustable particle size: The material particle size can be controlled by adjusting the gap between the rollers to meet different needs.

Multi-function: It can not only crush ores and building materials, but also be used to make artificial sand, cement mortar, etc.

Application fields

It is widely used in industrial sectors such as sand making, mineral processing, cement, metallurgy, chemical industry, building materials, etc. It can be used for medium and fine crushing of ores and rocks with medium hardness or below, such as limestone, slag, coke, coal, etc. It has obvious effect in the crushing and sand making of cobblestone materials.
