Medium Speed Coal Mill Hydraulic System

MP medium speed coal mill is a type of grinding equipment widely used in thermal power plants. It is used to grind and dry coal with various hardnesses. It is mainly composed of feeding device, main bearing, rotating part, transmission device, discharging device, high-pressure starting device and lubrication system. The MP medium speed coal mill adopts the grinding mechanism of roller and disc, which is characterized by high grinding efficiency, low power consumption, and low noise. It can grind coal with a moisture content of up to 15% and a hardness of up to 3.5. The coal is fed into the mill through the central feeding pipe and falls onto the grinding disc. Under the action of centrifugal force, the coal is crushed and ground by the grinding roller. The ground coal powder is blown by the airflow of the blower to the classifier, where the coarse particles are separated and returned to the grinding disc for re-grinding. The fine coal powder is collected by the dust collector and d…
