The machine is designed to produce super-fine powder or micro
powder of different materials with hardness less than 6 in Moh's
scale and humidity less than 6 percent such as kaolin, limestone,
calcite, marble, talcum, barite, gypsum, dolomite, bentonite mud,
mica, pyrophyllite, sepiolite, diatomite, graphite, alunite,
fluorite, potassium feldspar, phosphorite, pigment and so on. The
granularity of the end products is 325-2500 meshes (0.044-0.005mm).
Three-ring Micro Powder Mill Structure:
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. After being crushed by hammer crusher, big
materials become small ones and they are sent to the hopper by
elevator. The electromagnetic vibrating feeder sends them to the
middle of first layer of dial evenly; the materials will be driven
to the edge of dial by centrifugal force and fall into the ring
channels and are pressed, crushed and ground by the grinding rings
and rollers. After ground in the first layer of the dial, the
materials fall into the second and third layer and are crushed and
ground. The high-pressure centrifugal blower inhales air from
outside and blow the materials from the third layer to powder
classifier. The rotating turbo in the powder classifier makes the
coarse materials return to the mill and reground, while the fine
powder mixed in the air goes into the cyclone collector and is
discharged from the bottom via discharge valve. The air with very
little fine powder is purified by pulse dust catcher and discharged
by blower and muffler.
