MW series micro powder mill is a new kind of mill which is developed with more than 20 years’ experience of manufacturing grinding mills and absorbed and adopted foreign advanced technology. It is mainly used to grind low or medium hard raw materials.
1.Low investment cost.
2.High output rate of finished powders.
3.Long life of tear and wear parts.
4.Operation in grinding cavity, safe and reliable.
5.Super fine finished powders.
6.Environmental friendly, no pollution.
- Working Principle:
The main motor drives main axle and every layer rotating by reducer. Dail drives numbers of rollers rolling and rotating in the ring by pintles.
Big materials are crushed into smaller particles by hammer crusher. Then they are sent to store house by elevator. The electro-magnetic vibrating feeder sends the materials evenly to the middle of the upper dial. Under the function of the eccentricity, the materials scatter to the side of the circle and fall into the ring to be pressed, crushed and milled into pieces by rollers. After the first crush, materials fall into the second and the third layer. The pumping of the high-pressure centrifugal blower put the outside air into the machine. The coarse powder will be brought into the classifier.
The rotating turbine in the collector makes the coarse particles fall back for regrinding. The fine particles will come into the cyclone collector with the airflow and discharged by the discharging valve on the bottom of the collector. They are the final products. The airflow with little dust will be discharged through blower and muffler after being purified by the cyclone collector.
