Quality Products Calcium Carbonate Grinding Mill / Mills Machine
Higher Yielding, Lower Energy Consumption
Newly designed grinding curves of grinding roller and grinding ring
further enhance the grinding efficiency of Ultrafine Grinding Mill.
With the same fineness and power, the production capacity is 40%
higher than that of jet grinding mill and stirred grinding mill,
and the yield is twice as large as that of ball grinding mill.
However, the system energy consumption is only 30% of the jet
grinding mill.
Adjustable Fineness Between 325-2500meshes
Ultrafine Grinding Mill’s cage-type powder selector adopts German
technologies, which effectively increases the precision of powder
separation. In addition, multi-head cage-type powder selector can
be configured according to the users' requirements on yield,
fineness and sieving rate. The product fineness can be adjusted
between 325-2500 meshes, and the screening rate can achieve d97≤5μm
once.
No Rolling Bearing & Screw In Grinding Chamber
There is no rolling bearing and screw inside the chamber of
Ultrafine Grinding Mill, so users are free from worries about
damages on bearing or its sealing parts, and there is no machine
damage problem caused by loose screws. The lubricating device is
installed outside of the main shaft, so that lubrication without
shutdown can be realized externally, and the production can be
continued for 24h.
Dust Removal By Pulse Collector Makes Operation More Eco-Friendly
Ultrafine Grinding Mill is equipped with efficient pulse dust
collector, so no dust pollution generates during operation of the
entire milling system. Silencer and noise elimination room are
configured to reduce noises. The production is organized fully
according to the national environmental protection standards.
Working Principle
After hammer crushers break large bulky materials to smaller ones,
elevator works to send materials to material bin. Next, materials
are sent to the grinding mill evenly and they would fall onto the
dispersing plate firstly. When the grinding mill runs, dozens of
grinding rollers start to rotate and roll. Under the action of
centrifugal force, materials on the dispersing plate are then
thrown to the rim and drop to the grinding chamber. In the circuit,
materials would be squeezed and ground. After being ground several
times, materials are blown into the powder selector by airflow.
Under the action of the impeller of powder selector, materials
which fail to meet fineness would be sent back to grinding chamber
to get another grinding while qualified powders would be collected
by cyclone powder collector and discharged from the bottom as
finished products. Some remaining powders would be collected by
impulse dust remover and they may stick to the surface of
filler-bag. So, next, high-pressure airflow controlled by the
impulse valve blows the filler-bag to make it swell and shake
violently. This sudden shake can help kick off materials on the
filler-bag and collect them as finished products. After filtering,
the airflow would be discharged to the air. This system adopts an
open circuit and runs under negative pressure.

Note
1 The bulk specific weight is calculated by 1.6t/m³. When the width
of the feeding port is above 600mm, it is a large-scale machine
while when the width ranges from 300 to 600mm, it is a medium-sized
machine.
