Drum screening machine

The drum screening machine uses a deceleration system to reasonably rotate the center separation cylinder of the equipment. The center separation cylinder is a screen composed of several annular flat steel rings. The center separation cylinder is installed in an inclined state with the ground plane. During work, the material enters the cylinder net from the upper end of the center separation cylinder. During the rotation of the separation cylinder, the fine material is separated from the top to the bottom through the screen interval composed of annular flat steel, and the coarse material is discharged from the lower end of the separation cylinder into the crusher. The drum screening machine is equipped with a plate-type automatic screening mechanism. During the separation process, the screening mechanism and the screen body are relative to each other, and the screening mechanism continuously “combs” the screen body, so that the screen body is always kept clean during the entire working process, and the screening efficiency will not be affected by the blockage of the screen hole.
