High Pressure Grinding Mill, also called High Pressure Mill. It is suitable for producing powder in mineral, chemical, building and other industries. High Pressure Grinding Mill is suitable for grinding of all kinds of materials whose Moh’s hardness is below 9.3, such as calcium carbonate, barite, dolomite, calcite, limestone, kaolin, bentonite, marble, gypsum, quartz, feldspar, clay, talc, fluorite, clay, white mud, mica, refractory material, glass, total about 1000 kinds of materials. Internal structure and Working Principle of High Pressure Grinding Mill: The standard configuration of High Pressure Grinding Mill consists of main unit, reducer, powder classifier, cyclone powder collector, dust cleaner, blower, control cabinet motor and pipes. The optional accessories include crusher, bucket elevator, feeder. Big materials are crushed by jaw crusher to the required particle sizes, and carried by bucket elevator to the storage hopper, and are fed evenly and continuously by vibrating feeder into the main unit for grinding. The grinded powder are carried by the airflow from the blower to the classifier to be classified, the particles which meet the fineness enter cyclone collector through pipe, and are separated and collected there. They are discharged at the discharging valve to become finished products; The airflow is sucked to the blower by return pipe on the top of cyclone collector. The whole airflow system is a sealed circulation, and is circulated under positive and negative air pressure. 1.Ertical structure, so it has small footprint, strong system. 2.Compared with other mills, Raymond Mill has high passing rate - 99%.
