Are the grinding rolls and rings at Raymond mill durable

Raymond mill processing material crushing effect mainly by roller compaction and winnowing, at the time of processing ore or other materials for grinding roller and grinding ring will wear is better, some friends in the purchase of Raymond mill will ask you when the grinding roller and grinding ring can use how long, this time is the length of the properties of material and processing, and production time, some friends processing bluestone, work eight hours a day for three years all don't need to replace grinding roller and grinding ring. Some friends processing of bauxite, is also a work 8 hours a day, a month or two just need to replace grinding roller and grinding ring, even adopt wear-resisting material grinding roller and grinding ring also use not too long, this kind of material tenacity big not easy into powder, processing production is low, the material of sand with lron stronger is the fee of grinding roller and grinding ring. So, different material processing, operation of different time mill roller service life is not certain. At present, there are three kinds of alloys commonly used for grinding roller and grinding ring, such as manganese 13 and 65. These three kinds of alloys are commonly used, and their comprehensive performance is relatively good. While manganese 13 is wear-resistant, it is not suitable for processing some materials, and the quality of 65 manganese is low. When buying grinding rolls and rings of different materials, users should choose suitable ones according to the use situation and the characteristics of their own materials. The better the material is, the higher the price will be.
