Product description

The double roller crusher is another breakthrough in the field of sand and gravel aggregate production equipment manufacturing. The double roller crusher is a two roller sand making machine that uses two motors to drive the shafts to squeeze and grind materials. The double roller crusher is mainly used for fine crushing operations with particle size requirements of less than 80mm and finished products of 50mesh-20mm.

Sand Production Application

In sand production lines, the double-roll crusher functions as a sand-making machine, offering advantages such as no wear parts, low maintenance costs, adjustable sand particle size, high yield rate, and excellent sand particle shape. It is widely used in the sand-making industry.

Mineral Processing Crushing Applications

In the mineral processing industry, double-roll crushers or high-pressure roller mills are employed for fine crushing operations. Positioned upstream of ball mills, they can reduce 2-3 cm ore particles to less than 1 mm, significantly enhancing the operational efficiency of mineral processing ball mills and boosting overall production productivity.    

 

The roller crusher performs crushing operations through rollers. The material enters between the rollers through the feeding port and crushes the river pebbles through compression. There is a gap between the two rollers, and the gap between the two rollers increases, resulting in a larger particle size of the material. Under the action of the compression spring, the gap between the two rollers decreases, resulting in a smaller particle size of the material. By adjusting the gap, the discharge particle size of the material can be controlled.
