Pulverizer machine is for super-fine grinding materials with hardness less than 6 in Moh‘s scale and humidity less than 6 percent such as kaolin, limestone, basalt, calcite, marble, talcum, barite, gypsum, dolomite, bentonite mud, mica, pyrophyllite, sepiolite, carbon black, diatomite, graphite, alunite, fluorite, potassium feldspar, phosphorite, pigment, up to 200 kinds.
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 depending on the final size and the grinding materials.
The whole set pulverizer machine consists of:
1). Hammer crusher, bucket elevator, storage hopper, vibrating feeder,
2). Main unit, inverter classifier, cyclone collector, pulse deduster system,
3). High pressure positive blower, air compressors and electrical control systems.
Working Principle of pulverizer machine:
●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.
