Aluminium hydroxide, Al(OH)3, ATH, sometimes erroneously called hydrate of alumina, is found in nature as the mineral gibbsite and its three, much more rare polymorphs: bayerite, doyleite and nordstrandite.

Aluminium hydroxide/ Al(OH)3 powder grinding mill:
—— five models: BW-100, BW-200, BW-300
——finished production fineness: 300meshes~3000meshes, 5-47 micron
——the capacity (ton/hour) ranges from 0.2T/H to 5T/H

Main Components of Aluminium hydroxide/ Al(OH)3 powder grinding mill:
BW series Aluminium hydroxide/ Al(OH)3 powder grinding mill mainly consist of main unit, classifier, dust cleaner, powder collector, blower, muffler, hammer crusher (can be replaced by jaw crusher), bucket elevator, sound-proof room, storage hopper, vibrating feeder and so on.

Working Principle of Aluminium hydroxide/ Al(OH)3 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.
