Ø We do process designing & sizing of the
equipment as per site conditions, Raw material specifications and
product specifications. All the machinery / systems are optimized
as per site conditions. Reliable machinery is used for processes to
ensure high plant availability.
Ø Our plant machinery has increased life of wear prone
parts and replacement is needed once in one year. All systems are
designed on continuous rating with *4 hours, a day and seven days
in a week. Our after sales service takes care of customer need for
trouble free operation of the plant.

Working Principle of Micro Powder Grinding
Mill system
Â
HGM series micro powder grinding
mill system mainly consist of main unit, classifier, powder
collector, dust cleaner, blower, muffler, sound-proof room,
crusher, bucket elevator, storage hopper, and vibrating
feeder.
Â
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 turn plate by vibrating feeder and
sloping feeding pipe.
Â
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 turn plate by
thecentrifugal force
and fall down into the grinding chambers
where the materials are repeatedly pressed, crushed and grinded by
the rollers.
Â
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.

Features of Micro Powder Grinding
Mill
â—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.
Â
â—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 **3 times longer than impact mill or turbo
mill. Furthermore, the lifetime can reach **5 years for grinding
calcite carbonate.
Â
â—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.
â—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≤5μm.
â—Environment-friendly
The application of pulse deduster
and muffler greatly alleviates the dust pollution and
noise.
