Brief introduction Micro powder grinding mill is designed by our R&D department on the basis of multiple innovation and testing. It has been proved by thousands of customers that our machine has outstanding features, stable quality, easy operation and maintenance. It is the ideal equipment for fine powder milling. Application: Hgm series micro powder grinding mill is the equipment specializing in producing fine and superfine powder of non-inflammable, non-explosive and brittle materials with mohs's hardness under six, 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. Working principle: Hgm series micro powder grinding mill mainly consist of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder. After crushed by hammer crusher, the large materials become small ones and are sent to storage hopper by elevator, and then evenly sent to the upper distribution plate of the turn plate by vibrating feeder and sloping feeding pipe.
