How to process stones and rocks by ultra mill

Ultra mill is a miling machine specializing in producing fine and superfine powder of non-inflammable, non-explosive and brittle materials with Moh's hardness under six, the moisture under 5% such as  calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite and vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alunite, graphite, fluorite, rock phosphate, Kalium ore, pumice, etc., totally more than 100 kinds fomaterials.




The granularity of the finished powder size can be adjusted between 50 and 325 mesh(315-45micron). The ultra mill has five types: HGM80, HGM90, HGM100, HGM100A, HGM125.  Ultra mill is mainly consist of main unit, classifier, powder collector, dust cleaner, induced draft fan, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.

How does HGMseries Ultra mill work?
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.
