Raymond mill for lime powder2021-01-11 14:51:40
As a professional stone mill, the grinding objects of Raymond Mill are naturally all kinds of ores, including more than 280 materials such as phosphate rock, lime, calcite, barite, limestone, gypsum, bentonite, construction waste, and thermal insulation materials.
Material case analysis
Limestone pulverization is mainly used in various industrial raw materials such as power plant desulfurization, concrete mixing stations and chemical industries. Raymond mill can grind limestone into different powder specifications of 30-425 mesh according to actual applications. The common fineness of lime powder is 200 mesh and 325 Mesh, 800 mesh and other fineness, of which 325 mesh has a wide application range and a very large amount.
Construction waste is recycled and reused. Construction waste is different from ore. It is a mixed material, and its convenient properties are difficult to control, such as hardness, humidity, and presence or absence of impurities.
Under the premise that the recycling and reuse of construction waste and industrial waste solves the problem of environmental pollution, the effective use of resources can be described as killing two birds with one stone.
Construction waste can be reused in concrete materials after being processed by jaw crushers, industrial mills, sand making machines and other crushers. At present, construction waste recycling and reprocessing technologies are constantly being explored and innovated, and grinding equipment is required in the production process. And the quality of the finished products has been improved. The high-pressure suspension roller mills and European version mills developed and produced by Clirik Industries are all upgraded products of Raymond Machine. The finished products have uniform fineness, large output and high efficiency, and are just right for construction waste treatment.
Material performance requirement analysis
Although Raymond mill is a stone powder grinding device, it also has clear requirements for raw materials, such as raw material particle size, material hardness, humidity, etc.
1. The particle size of the material, the size of the feed inlet of the model mill varies, and the particle size of the Raymond mill feed is between 15mm-35mm. If the feed requirement is exceeded, it needs to be processed by the jaw crusher and other crushing devices.
2. Material hardness. Except for ultra-fine grinding, most ore mills can grind various non-flammable and explosive ore with Mohs hardness of 9.3 and below.
3. Material humidity. The material screening and conveying of the milling equipment is done by wind power. If the humidity is too high, it is difficult to grind the ingredients and powder to be sieved and conveyed. The grinder has strict requirements on humidity, and the general material moisture should be kept below 6%.
