Working Principle of HGM90 micro powder grinding mill equipment
The main bearing and each dial are driven by electromotor of main
machine through reducer, and numbers of rollers, which are rolling
in the ring, are driven by dial through plunger. After crushed by
hammer crusher, the big materials become small ones and are sent to
storage hopper by elevator and further sent to the middle of first
dial evenly by the electromagnetic vibrating feeder and feeding
pipe. 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
blow the crushed materials to classifier. The rotating turbo in the
powder concentrator will make the coarse material return to the
mill and reground, 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.
Performance and features of HGM90 micro powder grinding mill equipment
1. High efficiency
Under the same final size and power, the product capacity of
ultrafine mill is twice than jet mill and agitation mill.
2. Longer lifetime of spare parts
The roller and ring are made of special material, which improve the
grinding efficiency a lot. For same material and final size, the
lifetime of its wearing parts can reach to more than one year,
about 2-5 times as long as that of vertical shaft impact crusher
and turbo-mill. Especially when handling calcium carbonate and
calcite, the lifetime can reach 2-5 years.
3. High safety and reliability:
There are no rolling bearings and bolts in grinding cavity, so
problems caused by bolts shedding or wear of bearings and seal
components will never happen.
4. High fineness of products
The product fineness can reach D97<=5um.
5. Environment friendly
The application of pulse dust collector and muffler reduce the
pollution and noise of the dust, which has reached national
environment protection standard.
