COAL GRINDING MILL_GRINDER MILL MACHINE_Henan Yuhong Heavy Machinery Company( Yuhong Group

MTW Coal Grinding Mill--- the latest type of Raymond Mill, has become one of the most advanced coal grinding mills in the world with its so many intellectual properties like bear-gear drive, inner oil lubricating system, arc air channel, etc.

The MTW coal grinding mill is mainly applicable to grinding process of mineral materials in metallurgy, building material, chemical and mine industries, etc. It can process the non-flammable and non-explosive mineral materials of hardness less than 9 on Moh’s scale, and the humidity less than 6%, including quartz, feldspar, calcite, talcum, barites, fluorite, tombarthite, marble, ceramic, bauxite, manganese ore, iron ore, copper ore, phosphate ore, iron oxide red, zircon sand, mineral waste residue, water granulated slag, cement clinker, active carbon, dolomite, granite, granat, iron oxide yellow, chemical fertilizer, compound fertilizer, flyash, soft coal, coking coal, lignitous coal, magnesite, chromium oxide green, gold ore, red mud, clay, kaolin, coke, coal gangue, porcelain clay, kyanite, fluorspar, bentonite, medical stone, rhyolite, diabase, pyrophyllite, shale, red sandstone, stromatolite, basalt, gypsum, graphite, carborundum, thermal insulation material, etc..

The system consists of coal grinding mill, separator, air blower, jaw crusher, vibrating feeder, hopper, dust collector, pipe, powder collector, electric cabinet, motors, etc.

Big lump materials are crushed to required size by jaw crusher, then elevated to buffering hopper through elevator, after that fed into the mill to be ground. Materials are to be ground between ring and rollers, and move up with the air flow, those particles which cannot pass the separator will fall down and be ground again, while others will be collected as finished product. Air flow passing through separator will go to the air blower for recycling, it's a closed system.

1. Efficient
Bevel gear overall drive reduces noise and increases drive efficiency and capacity.Inner automatic thin-oil lubricating system makes better lubrication for bearings.
2. Economical
Edge-replaceable shovel saves you money and frequency-control separator and cyclone powder collector ensure high capacity.
3. Advanced
Arc air channel reduces energy consumption and intelligent control ensures better operation.
4. Environmentally friendly
Unique air recycling system and dust collector make clean environment.
