Selection Principle and Method of Raymond Mill Lining Plate Material

Raymond mill lining plate of the main role is the lining plate surface and the convex peak with grinding ball, repeatedly crushing and grinding of materials. Liner material selection has a great influence on the working performance of appropriate Raymond pulverizer . In this paper, the selection principle and selection method of liner material are introduced.

Material selection must be based on different conditions to determine the different material, which is used in the fine grinding chamber or rough grinding. The fine grinding chamber is the main form of the pattern lining board, the small corrugated liner board and the flat lining board. The difference of the effect of the coarse grinding and fine grinding is different, and the impact of the grinding body is different. The same mill diameter, the grinding body diameter of the coarse grinding chamber is big, the material block is also big, the impact on the lining plate is big, the wear rate is high, the situation is good.

Selection principle: the material is relatively resistant to abrasion or service life; it is appropriate to ensure the safety and reliability of the lining plate in the work process is very important. In addition to considering the cost of the lining plate, the installation fee, the replacement of the lining board, the labor service charge, the consumption of auxiliary materials and the production rate, etc..

Domestic and foreign research on liner material has been carried out, at present our country has already made the industry of wear-resistant steel material has 40~50, production process, mechanical properties and industrial application effect is different, now has formed a variety of small batch process characteristics. After practice, the fine grinding barn, with good effect of medium carbon alloy chromium manganese steel. In diameter in the range 3 to 5 meters of Raymond Mill coarse grinding bin should choose medium carbon low alloy Cr Mn, which has good wear-resistant effect and...
