What are the types of grindable grinding materials? What are the specific requirements? With these questions will be a general small series will give you a detailed analysis, in-depth understanding of Raymond machine on the applicability of materials introduced.
Analysis of the type of milled material
As a professional stone mill, the grinding object is naturally all kinds of ore, such as phosphate rock, lime, calcite, barite, limestone, gypsum, bentonite, talc, potassium feldspar, dolomite, activated carbon, marble, quartz , Glass, kaolin, cement, construction waste, insulation materials, such as more than 280 kinds of materials, high-fine powder grinding.
Material case analysis
Case 1: limestone milling is mainly used in power plant desulfurization, concrete mixing plant and chemical and other industrial raw materials, raymond mill can be used in accordance with the actual application of limestone grinding into 30-425 target different powder specifications, lime powder has a fine fineness of 200 Head, 325 mesh, 800 mesh and other different fineness, of which 325 mesh the most widely used, the largest amount.
Case 2: construction waste recycling, construction waste and ore are different, it is a mixture of materials, the convenience of the nature of difficult to control, such as hardness, humidity, with or without impurities, etc., in the current environmental shouting, the global call Under the premise of solving the problem of environmental pollution, let the resources be effectively used, can be described as double benefit, construction junk jaw crusher, industrial mill, sand machine, etc. crushing the ecological environment construction, construction waste, industrial waste recycling Machine processing can be re-user concrete materials, the current construction waste recycling and re-processing technology is constantly exploring and innovation, while the requirements of milling equipment in the production process and finished product quality has improved, SBM new development and production of high-pressure hanging roller mill, European version of the mill are part of the mine to upgrade products, finished fineness uniform and meticulous, and large output, high efficiency, for construction waste treatment just right.
Material performance requirements analysis
Raymond Mill is a stone powder grinding device, but there are clear requirements for raw materials, such as raw material particle size, material hardness, humidity and so on.
1, the size of the material particles, the type of mill size of the inlet size, 3R to 6R Raymond mill maximum feed size range between 15mm-35mm, if beyond the maximum feed requirements required by the jaw crusher Pretreatment of crushing unit.
2, the material hardness, in addition to ultrafine mill outside the majority of ore mill grinding Mohs hardness of 9.3 and below the following non-flammable and explosive ore.
3, the material humidity, grinding equipment, material screening, transmission by the wind to complete, the humidity is too easy to grinding components and powder sieving transport, grinding machine strict requirements, the general material moisture to be kept below 6%.
