Rotary type coal-gangue separation device

A rotary type coal-gangue separation device comprises a cylinder body. A rotary spindle is arranged in the cylinder body, the cylinder body is a fixed part, and a centrifugal swing wheel is arranged on the rotary spindle. A lining cylinder is fixed on an inner wall of the cylinder body, wherein the inner wall of the cylinder body corresponds to the centrifugal swing wheel. The centrifugal swing wheel comprises an upper swing wheel and a lower swing wheel, and a material collecting holler is arranged between the upper swing wheel and the lower swing wheel. In the rotary type coal-gangue separation device, a fixed roller is utilized and the centrifugal swing wheel is arranged on a rotary shaft, so that strong centrifugal force is applied to a coal-gangue mixture and the coal-gangue mixture collides with the cylinder body at a high speed. Therefore, the purpose of separation is achieved. The rotary type coal-gangue separation device is simple in structure, low in power consumption and good in separation effect,
