Alumina powder grinder

Alumina is a chemical compound of aluminium and oxygen with the chemical formula Al2O3. It is the commonly occurring of several aluminium oxides, and specifically identified as aluminium(III) oxide. It is commonly called aluminium oxides, and may also be called aloxide, aloxite, or alundum depending on particular forms or applications. To processing alumina, we have alumina mill, alumina powder grinder,which is mainly used in mining, building materials, chemical, metallurgical and other industries. It can process stone materials that moisture content less than 5%, Mohs hardness under 6 levels, such as kaolin, limestone, talc, barite, dolomite, calcite, marble, gypsum, bentonite, mica, graphite, and so on. The finished powder size can be 3000 meshs. Alumina powder grinder, the granularity (or final size) of the finished products can be freely adjusted between 325-3000meshes (0.045-0.0057mm), and the capacity (ton/hour) ranges from 0.4T/H to 12T/H. Working Principle of alumina powder grinder: ●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.
