Abstract

This utility model relates to the field of limestone processing technology and provides a crushing and dust prevention device for limestone processing. The device includes a limestone crushing unit, with a suction pipe connected to the top of the crushing unit via a groove. One end of the suction pipe is connected to a dust collection box. In this utility model, by connecting a separation box at the bottom of the dust collection box to the discharge port, dust falling from the dust collection box enters the separation box. A motor drives the connecting shaft and the outer spiral blades to rotate, creating a conveying force above the filter screen. Due to the action of the spiral blades, larger limestone particles are intercepted by the filter screen during the dust's movement and conveyed along the screen to the inside of the limestone crushing unit for further crushing. Smaller particles slide onto the conveyor belt at the discharge port at the bottom of the separation box, achieving the recycling and reuse of limestone, reducing resource waste, lowering production costs, and improving the resource utilization rate of the entire processing process.
