SBM Raymond mill is suitable for processing more than 280 kinds of materials such as barite, calcite, feldspar, talc,iron ore crushing plant marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass and insulation materials with less than 9.3Mohs hardness, high fine powder with 6% humidity, the non inflammable minerals of chemical industry, construction and other industries. When purchase the Raymond mill, manufacturers will always recommend that customers should buy some fittings of the mill, is it really necessary? During the following paragraphs, SBM Machinery will tell you the answer.
First of all, we need to know the fittings of Raymond mill include a speed reducer, wet grinding ball mill gear reducer, wind machine, grinder, plum frame, roller, analyzer, etc. In fact, 90% of these parts belong to the wearing components. Although they are only spare parts, once they are damaged, Raymond mill must be stopped to deal with the problem during the production process. It can be said that the effect of Raymond mill accessories is crucial to its duration and working efficiency. Therefore, it is right for Raymond mill manufacturers to advise users to buy the accessories.
Last but not least, knowing about the wear degrees of these parts is also important. That is to say, to what extent it will be scrapped, or the standards of the replacement are also needed to be learnt about.
1. When the wearing amount small gear surface is 30% less than its tooth thickness, diamond mining machines or the wear of big gear ring surface 25%greater than its tooth thickness, their reversible surfaces can be used. When the wear reaches 1/2, they will be scrapped.
2. The bases of the two bearings are on the same horizontal plane. If the external surface of the hollow shaft has trench scarred or the inner circle is worn, which may lead to the deformation and the crack of hollow shaft, it should be replaced immediately.
3. When the wear of the bearing tile is 1/3 greater than its thickness, it should be replaced in time.
4. When the distortion of the ring gear flange is greater than 7.5mm, it is scrapped
