Sepiolite is a kind of clay mineral which consists of magnesium and silicate. It is a typical formula for which is Mg₄Si₆O₁₅(OH)₂·6H₂O. It can be present in fibrous, fine-particulate, and solid forms. Sepiolite was first described in 1847 for an occurrence in Bettolino, Italy. The name comes from a perceived resemblance of the material to the porous bones of the cuttlefish from the Greek, "sepion". Because of its low specific gravity and its high porosity it may float upon water, hence its German name meerschaum ("sea foam").
 Sepiolite micronizer is professionally processing 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 of materials.
Finished Sepiolite powder fineness: 47-5 micron (325mesh-2500mesh)
Capacity: 0.4-12T per hour
 
Models Sepiolite Micronizer: HGM80/HGM90/HGM100/HGM100A/HGM125
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.
