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

1. Concrete foundation 2. Jaw crusher 3. Electro-vibrating feeder 4. Bucket elevator 5. Stock bin
6. Whirlwind powder collector 7. Pipeline 8. Bag-type dust collector 9. Classifier 10. Main unit 11. Fan

The system consists of limestone 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.
