The document describes the HGM grinding machine, which is used to produce micro powders for industries such as mining, construction materials, ceramics, and fertilizer. It consists of various components that feed materials into a grinding chamber with rollers, where the materials are repeatedly crushed and ground into fine powders. The powders are then classified and collected in a cyclone collector before being packed. The grinding machine offers benefits such as high efficiency, long-lasting parts, safety, flexibility in fineness adjustment, and an environmentally friendly design. Specifications of different HGM models are also provided.

HGM Mill, micro powder production line
consists of hammer crusher, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, cyclone collector, pulse
deduster system, high pressure positive blower, air compressors and electrical control systems.
Working Principle of HGM grinding machine,micro powder grinding mill:
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.
Benefit of HGM grinding machine
1.High Efficiency.
Under the same finished final size and the same motor power, the capacity of the machine is twice as much as jet mill, mixing
grinder and ball mill, and energy consumption decreased 30%.
2.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.
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, flexible adjustment.
The final fineness of the grinding materials can be adjusted between 325 meshes and 2500 mesh (47-5 micron), and the product
fineness can reach D97≤5μm.
5.Environment-friendly.
