AI Technical Summary
Existing crushing equipment generates significant amounts of dust during the waste crushing process, causing dust to spread and pollute the working environment, posing a health hazard.
A waste crushing device for recycled aggregate production was designed, comprising a crushing box, a dispersing roller, and a dust collection assembly. Dust is collected by the dust collection filter holes and dust collection chamber on the dispersing roller, and the filter holes are prevented from clogging by a reciprocating rotation mechanism. Combined with an air pump and a dust collection box, efficient collection of powder is achieved.
It effectively reduces dust diffusion, protects the working environment, and improves the efficiency of powder collection and the operational stability of the equipment.
