The document describes the HGM Micro Powder mill, which can mill materials into powder between 5-74 microns. It comes in 5 models with capacities between 0.4-30 tons per hour. The mill uses rollers and rings to grind materials into a fine powder, which is then classified and collected. Key features include high efficiency, long-lasting parts, safety, adjustable fineness between 5-74 microns, and environmental friendliness. It is produced by Shanghai Clirik Machinery Co. LTD.

Information
Types of Micro Powder mill:
—— five models: HGM80, HGM90, HGM100, HGM125and HGM1680L
——finished production fineness: 250meshes-2500meshes, 5-74 micron
——the capacity (ton/hour) ranges from 0.4T/H to 30T/H
Work Principle of Micro Powder mill:
HGM series Micro Powder mill 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 turn plate by
vibrating feeder and sloping feeding pipe. When the grinding mill is at work, the main bearing and
each dial are driven by electromotor through reducer, and all the grinding rollers are rolling in the
ring channels driving by dial through plunger. The materials are driven to the edge of the turn
plate by the centrifugal force and fall down into the grinding chambers. The high-pressure air
blower constantly inhales air, airflow with crushed materials are brought to 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

2. bottom; A small proportion of the fine powders, with airflow, moves to the dust cleaner. The
materials from the above two lots are sent by the conveyor to get finished powders packed. In
addition, filtered clean air will be emitted from muffler in the end.
Features of Micro Powder mill:
High Efficiency
Under the same finished final size and the same motor power, the capacity of Micro Powder mill
is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.
Long lifecycle of spare parts
The ring and roller are forged by special material with high utilization,the lifetime can reach 2-5
years for grinding calcite carbonate.
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.
High fineness, flexible adjustment
The final fineness of the grinding materials can be adjusted between 250 meshes and 2500 mesh
(74-5 micron), and the product fineness can reach D97≤5μm.
Environment-friendly
The application of pulse bag filter and muffler greatly alleviates dust pollution and noise.
Advanced intelligent speed control device
Convenient adjusting, more uniform particle size.
