Based on the dense medium coal preparation process of separating particle size limit, causing flotation separation size limit decrease, which led to some changes of the grain size composition of flotation plant, the increase of the content of fine grained caused a certain difficulty to dehydration link. Pressure filtration machine main function was to reduce product moisture, as far as possible recovery of flotation plant, the article introduced its principle, structure and technical parameters, combined with relevant industry standards to make the necessary process calculation and analysis, which provided reference for choosing flotation plant dewatering equipment.
