High pressure Grinding Mill for sale
High pressure suspension grinding mill which is suitable for grinding various ores, chemical raw materials, non-metallic materials etc. High pressure Grinding Mill for sale, Grinding Mill Main Structure: The high pressure grinding mill consists of main unit, powder fineness classifier, blower, and finished product cyclone collector, High pressure Grinding Mill for sale, cloth bag dust cleaner and connecting pipes.
Working Principle:
The lump material after being crushed by stone crushers or rock crushers is transferred to a hopper by the elevator, and fed uniformly, quantitatively and continuously by the vibration feeder into the grinding chamber of the main unit for grinding. The materials in the chamber are brought up by the spade and fed into the room between the grinding roller and ring for crushing.
The blower of high pressure grinding mill brings the air around the unit base into the grinding chamber, and the crushed materials are brought into the classifier. The coarse particles drop for regrinding, and the qualified fine particles are inhaled through the air current into the cyclone collector.
Then the particles are separated from the air current and discharged at the collecting end as finished powder. However, the air current returns back to the blower, and repeat the above-mentioned circulation.
In order to guarantee that the grinding machine performs under negative pressure, the increased air volume is discharged into the cloth bag dust cleaner through the redundant air pipe between the blower and main unit, and finally discharged into the air after purification.

Application:
high pressure suspension grinding mill is applied widely in mineral milling process such as iron ore grinding plants, coal mining industry, blast furnace slag process, powder grinding plants for lime, coal, feldspar, quartz, barite, gypsum, limestone, ceramic, slag etc whose hardness are less than level 9.3 and humidity below 6%.
According to the grinding experience, we know that the grinding materials are non-flammable and explosive coming from metallurgy, chemical industry, building materials production lines etc. The final size of products from grinding mill processing is between 80mm – 425mm.
High pressure grinding mill used in South Africa gold mining industry. Gold mining in South Africa typically involves methods such as panning, sluicing, dredging, hard rock mining, and by-product mining. For most effective gold mining in South Africa, the method used is hard rock mining, since reserves are typically fully encased in rock deep underground.
The invention of industrial air cooling and air quality control systems saw gold mines reach unprecedented depths – the deepest being 3900 meters. In the South African gold grinding process, high pressure suspension grinding mill is applied widely for grinding raw materials into industrial size usage.
