Description

Technical Field

[0001] The utility model belongs to the technical field of roller skin structures for double-roll crushers, in particular to a high-efficiency roller skin structure for double-roll crushers. Background Art

[0002] The double-roll crusher is a crushing equipment, named because its main crushing components are composed of two rollers. It has a simple structure and can perform medium and fine crushing of medium-hard and soft ores. It has the advantages of fine crushing particle size, strong processing capacity, simple operation, long service life, adjustable discharging particle size and wide application range.

[0003] The roller crusher mainly uses a V-belt or universal joint coupling to drive and adjust the gap between the two rollers, uses a spring or hydraulic cylinder to control the pressure of the rollers, and uses two rollers to squeeze and crush the materials. The material falls between the two rollers through the feeding port, and falls after being squeezed and crushed by the rollers. When encountering materials that are too hard or unbreakable, the rollers can automatically give way through the action of hydraulic cylinders or springs, so that the gap between the two rollers is expanded, and the hard or unbreakable materials fall, thereby preventing damage to the machine.

[0004] The outer surface of the existing roller (roller skin) is provided with outwardly protruding bumps to increase the crushing force on the material. However, during the crushing process, the material is often stuck in the gap between adjacent bumps, or the material cannot be separated from the roller skin surface due to its certain viscosity. When the roller skin rotates one circle, the crushing efficiency of the material is affected. Summary of the invention
