In view of the problems of the traditional interference bed separator, such as hole plugging, wall material accumulation and discontinuity of tailings discharge, the mechanical structure of the separator is improved and optimized, and a forced discharge jammer is added, rotating at a constant speed in a flow field at a low speed. According to the laboratory model, the flow field distribution in the main tank of the separator is numerically analyzed to determine the rotational speed and range of the forced discharge jammer, the experiments of slime screening, disturbing bed separation and coal slime floating and sinking are carried out on the 1 / 3 coking coarse coal slime. The analysis and experimental results show that the possible deviation of Pulse Continuous Discharge-type Interference Bed Separator on 1 ∼ 0.25mm narrow-grained coarse slime is 0.146, indicating that the separation effect is better.
