Application of
vertical powder
grinding mill:
Vertical powder
grinding mill is the equpment to produce fine and
superfine powder of non-inflammable, non-explosive and brittle
mineral, chemical and construction, such as calcite, carbon
black,chalk, limestone, dolomite, kaolin, gypsum, and talc etc,
totally more than 100 kinds of materials.
The
structure of vertical powder
grinding mill:
Vertical powder
grinding mill is mainly composed of bucket elavator,
hopper, main unit, cyclone powder collector, dust cleaner,
muffler, blower, soud-proofroom and so on.
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 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.
Advantages
