Introduction of High Pressure Grinding Mill:

High Pressure Grinding Mill also is called High Pressure Roller Mill. It is suitable for producing fine powder in mineral, chemical, building and other industries. 

High Pressure Grinding Mill is suitable for grinding variety 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, refractory material, glass, etc.

Working Principle of High Pressure Grinding Mill:

High Pressure Grinding Mill consists of main unit, reducer, powder classifier, cyclone powder collector, bag filter, blower, electric control cabinet, motor and pipes. The optional accessories include jaw crusher, bucket elevator, feeder, hopper, powder packing machine, etc.

► Big materials are crushed by jaw crusher to the required particle sizes less than 30mm.

► Crushed material is carried by bucket elevator or belt conveyor to the hopper, and under the bottom of hopper there is vibrating feeder.

► Crushed material is fed evenly and continuously by vibrating feeder into the main unit for grinding mill. The grinded powder are carried by the airflow from the blower to the powder classifier to be classified, the particles which meet the fineness enter cyclone collector through pipe, and are separated and collected in the cyclone powder collector. They are discharged through discharging valve as finished powder 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.

► Electric control cabinet is used to control the whole QBM Series Grinding Mill System. On the electric control cabinet there is special meter for powder classifier. By this special meter can easily to adjust the rotation speed of powder classifier, then to control the needed powder output fineness of finished powder product in the range of 80- 425 mesh.
