Raymond and the advantage over a centrifugal mill, Raymond mill lithopones not only, you can also wear other material; 2, Raymond internal separators, you can adjust the fineness, so good milling fineness, uniform particle size, less coarse particles; 3, because Raymond is centrifugal force to squeeze through the balance wheel and abrasive material crushing to achieve, so the crush of lithopones relatively smooth particle shape, particle relatively strong, finished decrease oil absorption, whiteness and achromatic power increased; 4, large output, electricity province. A Raymond machine output per hour than the centrifugal one five rolls 600 will wear large 3-5 times. 5, due to the centrifugal mill body mostly made of cast iron, when crushed lithopone, body wear more serious, iron contamination can sometimes lithopones in iron content increased, affecting lithopones color and luster. Some manufacturers use the inner wall of stacked tungsten carbide electrode method of reducing wear and tear, and achieved certain results, mills, but pollution is still large, and Raymond of material worn much less pollution. Raymond mill in consumable wear inevitably Raymond mill at work, when you want to achieve the purpose of grinding, the material is extruded through mutual grinding roller and grinding ring so as to achieve the purpose flour, so Raymond mill in the case of wearing scuffed is inevitable. Therefore, the user when using the Raymond mill usually pay attention to maintenance of equipment maintenance, the timely replacement of damaged parts accessories. Raymond wearing parts are grinding rolls, grinding rings, roller assembly, shale mill, Raymond mill use is necessary to change after hundreds of hours of grinding rolls. Many users are aware of this, but many mills appeared in the course of a problem can not be solved correctly. Raymond roller and disc lining material is generally high chrome cast iron or nickel-chromium alloy, and such material has frequent breakage, loss is very serious, especially in cut-off loss, it is impossible to estimate. To analyze this, Raymond affect the hardness and fracture of materials, heat treatment and fracture affect parts of post-processing of raw materials, Raymond mill, parts rub against each other and the fracture. According to the company annual production experience Raymond, for the above, make the following solutions. Raymond parts wear is our goal, we all know that the harder the more wear-resistant products, so to make a more wear-resistant grinding roller and grinding ring seems very simple, because you just try to improve its hardness that is can, so many foundry casting flaunt their chromium content reaches 30%, HRC hardness of 63-65, but in fact not the case. The higher the hardness, castings contained carbide (Cr7C3) requires more quantity, the more diffuse distribution form the micro voids and micro-cracks in the matrix and carbide greater the chance of an interface, but also the probability of fracture greater. And the harder the harder cutting items. So casting out both wearable and not easily broken product is not so easy. Raymond casting extrusion load stress and grinding martensite easy to crack, eutectic carbides along the grain boundary precipitation into a network, because it will promote the brittle crack propagation, residual austenite exists when When a good stop extending cracks.
