Ferrosilicon screening device

A ferrosilicon screening device belongs to the technical field of screening devices and comprises a screening box, a material guiding plate, a screening plate and a screening plate driving assembly, the material guiding plate is obliquely arranged in the screening box relative to the horizontal plane, the screening plate is arranged below the material guiding plate, the inclination direction of the screening plate is opposite to that of the material guiding plate, and the screening plate driving assembly is connected with the screening plate and used for driving the screening plate to swing. Crushed ferrosilicon blocks slide onto the sieve plate through the material guiding plate, and the sieve plate is driven by the sieve plate driving assembly to do up-and-down reciprocating swing motion so as to screen the ferrosilicon blocks. The silicon iron block screening device is simple in structure, the material guiding plate and the screening plate are arranged in a relatively inclined mode and used in a combined m
