Impurity screening equipment for superfine slag powder

The utility model provides impurity screening equipment for superfine slag powder, which relates to the technical field of cement production equipment and comprises a feeding device and a screening device, the bottom of the feeding device is fixedly connected with the top of the screening device, the feeding device comprises a feeding bin and a driving motor, and the top of the feeding bin is fixedly connected with the bottom of the driving motor. By arranging the two feeding hoppers, it is avoided that slag powder is poured into the feeding bin at a time, and blocking is easily caused by too much slag powder in the feeding bin, the driving motor drives the stirring piece to rotate, and screening of the slag powder is more uniform; the rotating motor drives the sieve plate to rotate left and right to accelerate separation of impurities and mineral powder, the screening effect is better, after the impurities are treated, the switch piece is pressed to enable the rotating motor to drive the sieve plate to turn
