The differences between micro powder mill and other machine:
1. HGM series micro powder mill is highly efficient (twice as much as jet mill, mixing grinder and ball mill)
2. The spare parts of micro powder mill can serve much longer time (2-3 times longer than that of impact mill or turbo mill.
3. High safety and reliability of the micro powder mill (no rolling bearings and screws in the grinding cavity, so no problems caused by the wear of bearings or screws)
4. The micro powder mills are characterized by high fineness (final size: 325-3000 mesh, D97<5 micron), but other machine can’t reach those fineness.
5. Environment-friendly
Working principle of
micro powder mill:
The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of rollers, which are rolling in the ring, are driven by dial through plunger. After crushed by hammer crusher, the big materials become small ones and are sent to storage hopper by elevator and further sent to the middle of first dial evenly by the electromagnetic vibrating feeder and feeding pipe. The materials will be driven to the edge of dial by centrifugal force and fall down into the ring, crushed and grinded by roller, and become powder after production of three rings. The high pressure centrifugal blower will inhale air from outside and blow the crushed materials to classifier. The rotating turbo in the powder concentrator will make the coarse materials return to the mill and reground, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is at the bottom of it. The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler.
