Stone Grinding Mill Advantages
1. High Efficiency: Under the same finished final size and the same motor power, the capacity of stone grinding mill is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.
2. Energy Saving: compare with the comon stone powder grinding machine, the HGM minerals grinding machine can decrease about 20%~30% electrinic consums.
3. Long Service Life: because the grinding 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 2-3 times longer than impact mill or turbo mill.
4. Environment Friendly: the application of pulse bag filter and muffler greatly alleviates dust pollution and noise.
5. Cheaper Price& High Quality: because our Shanghai Clirik is the HGM series grinding machine manufacturer, so you can get machine from us in the cheapest price, and at the same time we also can supply the warmly after sale service.
Stone Grinding Mill Working Principle
When the stone grinding mill is at work, the main bearing and each dial are driven by electromotor of main equipment 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 where the materials are repeatedly pressed, crushed and grinded by the rollers. Then the materials fall into multiple layers and to be crushed and ground continuously to micro powder.
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.
