HGM Series Super Micron Mill And Micro Powder Production System Ore
Grinding Mill
1. Working principle
The motor of the micro grinding machine drives the spindle and the
turntable of each layer to rotate through the reducer, and the
turntable drives dozens of ring rollers to roll and rotate freely
in the raceway of the grinding ring through the pin.
Large pieces of material by the hammer crusher broken into small
particles into the storage bin by elevator, electromagnetic
vibrating feeder will material evenly to the centre of the wheel,
on the material under the action of centrifugal force to circle
around, and fall into the inside of the ring raceway is stamping
ring rolling, roll grinding, grinding and crushing, the material
after the first layer crushing and fall into the second and third
layer, Small particles of material after thousands of times of
impact, rolling and rubbing into ultrafine powder, in the high
pressure centrifugal fan suction action will be external air
inhalation machine, and the third layer of pulverized coarse powder
into the powder separator.
The eddy current generated by the rotating turbine in the powder
separator makes the coarse granular materials fall back and
reground. The fine powder enters the cyclone powder collector with
the airflow and is discharged from the discharge valve at the
bottom of the cyclone powder collector, which is the finished
product. The airflow with a small amount of fine dust is purified
by the pulse dust collector and discharged through the fan and
muffler.
2. Performance characteristics
(1) The micro grinding is efficient and low consumption. Under the
same material, power and fineness of finished product, the output
is 40% higher than that of air mill and agitation mill.
(2) The micro mill has a long service life. In the case of the same
fineness of materials and finished products, the service life of
wear parts is longer than that of impact crusher and turbine
crusher, generally up to more than 1 year.
(3) There is no rolling bearing or screw in the grinding cavity.
There is no bearing and its seals and fragile screws easily loose
and destroy the machine and other problems
(4) The fineness of the ultrafine grinding product can reach D97
≤5μm at one time
