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, Raymond would use hundreds of hours after changing roller. 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, the impact of post-processing of raw materials accessories heat treatment and fracture of 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, mills, because you just try to improve Its hardness can be, Raymond mill, so many foundry casting flaunt its 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, when eutectic carbides along the grain boundary precipitation into a network, high pressure mill, will promote its brittle crack propagation, superfine Mill, the presence of residual austenite at this time to prevent the extension of a good crack. Ring medium speed mill main features. Ring medium speed micro powder mill efficiency and low consumption. In the materials, power, the same situation fineness, 40% higher than airflow mill and mixing mill production. 2. Ring medium speed micro powder mill long service life. Under the same materials and fineness of the case, longer than the impact crusher and turbine crusher wear parts life, usually up to 1 year. 3. Cavity without rolling mill, no screws. There is no bearing its seals and wearing loose screw easily and destruction machine and other issues. 4. Product fineness can reach a d97≤5μm.
