stone grinding mill, which is called stone mills; stone grinding machine; stone grinder; stone processing machine; stone milling machine; stone pulverizer; stone mill equipment; stone pulverizing machine; stone powder machine; stone grinding plant, is professionally producing fine powder or ultra fine powder. Clirik is specializing in research, manufacture and sales of all kinds of mining equipment. Stone grinding mill, which is designed by our engineer and technicians on the basis of multiple innovation, test and experience over two decades, has absorbed many advantages of home and abroad mill manufacturing technique. 
Finished Silica powder fineness: 47-5 micron (325mesh-2500mesh)
Capacity: 0.4-12Tper hour Models stone grinding mill : HGM80/HGM90/HGM100/HGM100A/HGM125
Input Silica size: ≤20mm
Working principle:
1) After crushed by hammer crusher, the large materials become smaller pieces and are sent to the micro powder grinding mill.
2) When the micro powder grinding mill is at work, the granulated materials are crushed and grinded by the rollers into particles below 47micron.
3) The high-pressure air blower constantly inhales air within the micro powder grinding mill.
4) Along with the high speed airflow, micronized materials are brought to the classifier.
5) The qualified particles are screened and driven into the cyclone powder collector, finally exit from the discharging valve at the bottom;
6) A small proportion of the fine powders, with airflow, moving to the dust cleaner. Filtered clean air will be emitted from the air outlet of muffler in the end
