A coal crushing and separation device was designed. The synchronous rotation of the crushing roller and the rotating rod is achieved through a belt pulley transmission system and a cam mechanism, which drives the screening plate to slide in the feed box. Combined with the reset component and spring-assisted screen plate reset, the instantaneous crushing and screening of coal can be achieved.
This improves the working efficiency and screening stability of the coal crushing and separation device, ensuring the stability of product quality.
