Raymond mill grinding roller and improve the life of the disc

By grinding disc roller mechanism Raymond mill known: between particles in the presence of the roller and the grinding disc sliding process is inevitable, sliding under high pressure will inevitably have a greater friction, so the disc and rapid wear of the roller. The following are several ways you can effectively extend the life of the disk and roll:
(1) Use good corrosion resistant materials, in order to solve the economic costs and processing problems, can be double-metal composite method;
(2) the bed liner on the roller shell and the disc should be used to facilitate the replacement of the structure, the timely replacement of worn parts can not only improve the life of the disk and roll, but also to ensure the quality and yield of grinding products, extend the machine's life;
(3) minimize the human feed size and choice of appropriate loading force. Such as the use of hammer crusher fine-grained granular material crushing first before adding the mill is an economical and a good way to improve the efficiency of the mill. The results showed that when the mill feed size is small, the mill smooth, high yield, small grinding roller and disc wear. Another load force to meet production requirements and grinding fineness can be, excessive loading force will accelerate the roller and disc wear;
(4) In the mill to meet the conditions of use, you should reduce the operating speed of the disc and the roller. While improving certain range can increase speed, but when the speed exceeds a certain value, not only reach the aforementioned object, the life of the yield and efficiency, but also adversely affect other parts of life.
