Grinder Mill Description

High pressure suspension grinder mill is widely used in making fine powder or micro powder, a new kind of machine for producing fine powder. It is mainly used for grinding the material with middle and low hardness, moisture below 6%, and the material should be non-explosive and non-flammable, such as: calcite, chalk, limestone, dolomite, kaolin, bentonite, steatite, mica, magnetite, iolite, pyrophillite, vermiculite, meerschaum, attapulgite, diatomite, barite, gypsum, alunite, graphite, fluorite, phosphate ore, potassium ore pumice, etc. The size of the finished product can be adjusted between 325-2500 mesh.

Grinder Mill Working PrincipleThe whole machine is collocated with jaw crusher, elevator, hopper, electromagnetic vibrating feeder, main unit, classifier, collector, cloth deduster and high-pressure blower.

In the main frame,a 1000-1500kg high pressure spring is fixed to the roller suspender.After the grinder is put into effect,the roller will circumgyrate around the main shaft,and rolls chosely against the grinding ring effected by the high pressure is 1.2 degree than Raymond mill.When the stuff is loaded into the grinding cavity,it is shoveled into the space between the roller and the ring for grinding.The grinded powder goes into classifier along with the circulation wind of the blower and the standard finenesspowder is guided to the cyclone collector as finished and lager size stuff falls back to the grinder for regrinding.The circulation wind returns to the blower to repeat the above process and the after wind enters into bag dust cleaner for purification.When there is abrasion between roller and ring,it is recommended to adjust the length of the spring to maintain the constant pressure between the roller and the ring hence to be ensured,the stable output and fineness.
