How does medium speed mill process and grind materials?

The fineness of the grinding depends on the wear degree of the roller. Only when the roller is in good condition, can a higher production capacity and qualified product size be obtained. Therefore, it is necessary to pay attention to the problems in the middle speed grinding and the operation. It is necessary to inspect the wear of the rod skin regularly and repair and replace it in time. The roller shell of medium speed mill is gradually worn out. The main factors affecting the wear of the roller skin are the hardness of the material to be treated, the strength of the roller shell material, the surface shape and size of the roller, the operating conditions, the feeding mode and the feeding ratio, etc. The service life of the roll cover and the technical index of the roll work depend on the uniformity of the material distribution along the whole length of the roll. If the material distribution is not uniform, the roller not only wears quickly, but also the surface of the roller will appear ring groove planting, so that the grinding product calibration is not uniform. In addition to crushing mill, all cement medium-speed mills are equipped with a feeder, the length of the feeder should be equal to the length of the roller, to maintain uniform feeding along the length of the stick.
