Pumice Powder Grinding Mill, Brand Name : SBM

Pumice powder grinding millstone powder grinding mill
it can grind not only dolomite stone but also other 100 kinds of materials, such as gypsum, calcite, coal, chalk, limestone, dolomite and so on. It is mainly applied to non-inflammable, non-explosive and brittle materials with mohs hardness scale under six.
The product fineness of barite milling machine can be controlled between 325~2500 mesh (47~5 micron).
Production line configuration of pumice powder grinding millstone powder grinding mill
the whole set barite mill grinder consists of hammer crusher, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, powder collector, dust collector, air blower, air compressors and electrical control systems.
Working principle of pumice powder grinding millstone powder grinding mill
the crusher will crush the big materials into small ones, and then the elevator will send them to the hopper.
The vibrating feeder will send the materials to the middle of first dial evenly.
The motor of main equipment drives the main shaft and dial through reducer, and the dial drives numbers of rollers moving in the ring channels via pins.
The materials will be driven to the edge of dial by centrifugal force and fall down into the ring, crushed and grinded by roller, and become powder after production of three rings.
The high pressure centrifugal blower will inhale air from outside and bring the crushed materials to classifier.
The rotating turbo in the powder collector will make the coarse materials return to the mill and regrounded, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is at the bottom of it.
The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler.
