Choose the Right Grinding Mill 2015-01-04

In most industries, the size reduction can be divided into two general categories: crushing and milling. Crushing typically means reducing large chunks to small particle sizes about 0 to 20mm, in diameter or smaller. Milling usually means reducing material to sizes in the low micron or even nano-size range. Crushing mostly is done dry by crushers while attrition milling may be done wet or dry.

In mining industry, construction industry and many chemical operations frequently require finer materials; media milling is one common way to achieve the desired results. Grinding milling technology plays a significant role in mining, construction and chemical processing. Proper selection of grinding mill is vital for success.

There are many different types of grinding mills. Some devices, such as ball mills, are more suitable for coarse materials, and the output size is from 30 to 300 mesh. Another factor, we should consider is the power consumption. Ball mill is quite high consumption. Ball mills use "large" media, ranging in size from 20 mm in diameter and up, to produce material to mesh sizes.

HGM ultra fine grinding mill, is a kind of dry mill, and is more appropriate for super fine size particles. This mill utilizes rollers and ring to produce material ranging in size from approximately 5 to 74 micron.

HGM ultra fine grinding mill is quite simple and effective. Feed material is placed and feeding by vibrating feeder. Then enter into the grinding chamber. Both impact and shearing action result in size reduction as well as homogeneous particle dispersion with very little wear on the edges. These efficient forces must be present for the most effective grinding action. The whole HGM ultra fine grinding mill has power collector, dust cleaner and electricity control system to ensure the efficiency automatic operation.

For the grinding chamber of HGM ultra fine grinding mill, the roller and turn plate do not contact with the ring, thus can guarantee the impact and the output size. In addition, it can also enhance the roller, ring, turn plate serve life.
