Description
Fine milling machine, which is designed by our
engineers and technicians on the basis of multiple innovation, test
and experience over two decades, has absorbed many advantages of
home and abroad mill manufacturing technique. It has been proved by
thousands of customers that our machine has outstanding features
and stable quality. Our
Fine milling machine can
upgrade its production and the additional value which is suitable
for our customer to use. It is the ideal equipment for fine
milling.
Fine milling machine is the equipment specializing
in producing fine and superfine powder of non-inflammable,
non-explosive and brittle materials with Mohs's hardness under six,
such as calcite, chalk, limestone, dolomite, kaolin, bentonite,
talc, mica, magnesite, illite, pyrophyllite and vermiculite,
sepiolite, attapulgite, rectorite, diatomite, barite, gypsum,
alunite, graphite, fluorite, rock phosphate, Kalium ore, pumice,
etc., totally more than **0 kinds of materials.
Working Principle of Fine milling
machine:
Fine milling machine mainly consist of main unit,
classifier, powder collector, dust cleaner, blower, muffler,
sound-proof room, crusher, bucket elevator, storage hopper, and
vibrating feeder.
After crushed by hammer crusher, the large materials become small
ones and are sent to storage hopper by elevator, and then evenly
sent to the upper distribution plate of the turnplate by vibrating
feeder and sloping feeding pipe.
When the
Fine milling machine is at work, all the
grinding rollers are rolling in the ring, and the materials are
driven to the edge of the turnplate by the centrifugal force and
fall down into the grinding chambers where the materials are
repeatedly pressed, crushed and grinded by the rollers.
The high-pressure air blower constantly inhales air within the
Fine milling machineand, in turn, the
airflow with crushed materials are brought to the classifier whose
high-speed impeller will screen the airflow: the unqualified
particle size will fall and return to the mill for being reground
while the qualified particle size mixed with air will go into the
cyclone powder collector. Most of the qualified powders will fall
and exit from the discharging valve at the bottom; a small
proportion of the fine powders, with airflow, moves to the dust
cleaner, and clings to the surface of the filter bags. At the same
time, the fine powders clinging to the surface fall down by the
sudden vibration of the filter bags, which is caused by the
instantly ejected high-pressure gas controlled by the pulse valve.
The materials from the above two lots are sent by the conveyor at
the bottom to get finished powders packed. In addition, filtered
clean air will be emitted from the air outlet of muffler in the
end.
