Alum earth stone powder grinding machine is designed to produce micro powder alum earth. Alum earth stone powder grinidng machine has five types:HGM80, HGM90, HGM100, HGM100A, HGM125. HGMseries ultra fine grinding machine mainly consist of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.
Working Principle of Alum earth stone powder grinding machine
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.
