Micro Powder Mill, is also HGM micro powder grinding mill, micro powder grinder, fine powder grinder, or powder grinder mill. Output size of Micro Powder Mill is finer than ordinary grinding mill, first one is 30-3000mesh, and the second one is several hundred mesh.But how does Micro Powder Mill Work? Or we can see what the working principle of Micro Powder Mill is. Let us talk about it:
When Micro Powder Mill is at work, all grinding rollers are rolling, then the materials are driven to the edge of the turnplate by the centrifugal force, 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 powder grinder 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.
