Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand processing, and particularly relates to a crushing device for quartz sand. Background Art

[0002] The crushing of quartz sand is generally carried out by a material-hitting material quartz sand crusher, which is a machine that uses the self-collision and high-speed friction between raw materials to achieve crushing. It mainly breaks through the kinetic energy of the material itself. The material therein is accelerated by centrifugal force and then forms a lining inside the machine. Through high-speed rotation, the self-collision and friction between the materials are realized, thereby achieving crushing. At the top of the workbench of the existing crusher, there is a motor, and the output end of the motor drives the crushing unit to carry out the crushing operation of quartz sand through a transmission member. Generally, the output end of the motor and the transmission member are covered and protected by a welded channel steel. Due to the covering of the channel steel, it is inconvenient for the staff to carry out the maintenance and repair of the output end of the motor and the transmission member. In order to solve the problem that the protective channel steel is inconvenient to disassemble and maintain, a new type of crushing device for quartz sand is needed. Content of the Utility Model
