Solid waste recovery livestock and poultry feed granulation coarse and fine material centrifugal separation device

The invention relates to the technical field of feed granulation coarse and fine material centrifugal separation devices, in particular to a solid waste recovery livestock and poultry feed granulation coarse and fine material centrifugal separation device. According to the technical scheme, the centrifugal screening machine comprises a machine body, a screen drum installed in the machine body in a sliding mode, a stroke feeding mechanism installed in the machine body, a centrifugal screening mechanism installed in the machine body and located in the screen drum, and a discharging mechanism installed in the machine body and located in the screen drum, and the centrifugal screening mechanism drives the feed in the screen drum to be in uniform contact with the screen drum. When the screen drum rapidly moves to the left side and slowly moves to the right side, feed in the screen drum can move to the right side relative to the screen drum, the speed of the feed passing through the whole screen drum can be delayed,
