Airflow crushing and screening equipment capable of improving powder throughput

The airflow crushing and screening equipment comprises a filter box, a material receiving box is arranged at the bottom of the front surface of the filter box in a penetrating mode, and an electric telescopic rod is movably connected to the top of an inner cavity of the filter box. The ends, away from the inner cavity of the filter box, of the electric telescopic rods are movably connected with filter plates through rotating shafts. Through cooperative use of the electric telescopic rod, the filter plate, the waste box, the connecting shell, the feeding pipe, the charging opening, the air outlet pipe, the filter barrel, the filter cylinder and the fan, the circular crushing device has the advantage of circular crushing, and solves the problems that existing screening equipment can only perform simple screening, and cannot automatically return unqualified waste to be crushed again, so that the screening efficiency is greatly improved. The problems that waste materials need to be manually collected and then cru
