powder
mill grinding mill 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.
Vertical
grinding millmainly
consists of main unit, classifier, powder collector, dust
cleaner, blower, muffler, sound-proof room, crusher, bucket
elevator, storage hopper, and vibrating
feeder.

Working principle
of  powder
mill
 After
crushed by hammer crusher, the large materials become small ones
and are sent to storage hopper by elevator, edge of then evenly
sent to the upper distribution plate of the turnplate by
vibrating feeder and sloping feeding pipe. When the grinding mill
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 grinding mill and, in turn, the air flow 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 an 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.

Features
of powder
mill
1.      High
efficiency
Under the
same finished final size and the same motor power, the capacity
of micro powder grinding mill is twice as much as jet mill,
mixing grinder and ball mill.
2.      Long
lifecycle of spare parts
The ring and
roller are forged by special material with high utilization.
Under the same grinding material and finish special size, the
lifecycle of spare parts is about one year, which is **3times
longer than impact mill or turbo mill. Furthermore, the lifetime
can reach **5 years for grinding calcite
carbonate.
3.      High
safety and reliability
As no
rolling bearings or screws in grinding cavity, there are no
problems caused by bolts shedding or rapid wear of bearings and
seal components.
4.      High
fineness and flexible adjustment
The final
fineness of the grinding materials can be adjusted between **5
meshes and ***0 meshes, and the product fineness can reach
D*7<5um.
5.      Environment-friendly
