Rotary type coal gangue separation device

A rotary type coal gangue separation device comprises a cylinder body. A rotary main shaft is arranged inside the cylinder body. The cylinder body is a fixed part. A centrifugal swing wheel is arranged on the rotary main shaft. A linear cylinder is fixed on the inner wall, corresponding to the centrifugal swing wheel, inside the cylinder body, wherein the centrifugal swing wheel comprises an upper swing wheel and a lower swing wheel. A material collecting hopper is arranged between the upper swing wheel and the lower swing wheel. According to the rotary type coal gangue separation device, a fixed rotary cylinder is adopted. Due to a manner that the centrifugal swing wheel is arranged on the rotary shaft, strong centrifugal force is applied on a coal gangue mixture, and the separation aim is achieved by high-speed collision between the coal gangue mixture and the cylinder body. The rotary type coal gangue separation device is simple in structure, low in power consumption and good in separation effect. After ve
