Whether in Mineral Beneficiation ball mill or milling process applications more widely. Production in the manufacturing beneficiation mill mainly in the following seven major plates that, like the cylinder, liner, into the unloading device, gear, main bearings, diaphragms, balls, etc., which ball is the ball in the whole system Powder Production significant role. Let us work together to learn our manager beneficiation beneficiation ball mill material selection techniques. Dressing ball mill is generally based on the material can be divided into two types: one is the main alloying elements chromium white cast iron called iron-chromium alloy, chromium alloy cast iron casting material called chromium alloy cast iron ball ball; wear-resistant steel ball specifications are: low chromium ball mill specification (20-130mm), the chrome ball mill specification (20-130mm), high chrome ball mill three. Diameter ball mill generally 120,110,100,80,60,40,30 like. The other is to ductile iron casting material is called ductile iron grinding balls, which by the matrix structure obtained by heat treatment is mainly referred to the bainite bainite ductile iron grinding ball iron ball; obtained by heat treatment The matrix structure is mainly martensitic ductile iron ball ball ball called martensite. Different materials beneficiation ball mill having a high hardness, good toughness, broken small, high hardness, low wear, China's cement industry is currently the most commonly used grinding media. It can also be widely used in magnetic materials, chemicals, coal slurry, pellets, mining, cement, power generation, slag, superfine powder, fly ash, calcium carbonate, quartz sand, flue gas desulphurization and other industries mill It is a relatively good ball mill. Improve the mill output and quality of a few key issues, problems 1.1 mill production problems Generally speaking, direct way to improve the mill output has three kinds: 1. Plus home before the mill crushing machine; 2. Improved grinding system, improve grinding efficiency; 3. Plus home high efficiency separator. The above-mentioned three methods, any one kind of mill can greatly improve the yield. Of course, if factory conditions permitting, supporting the use of the above three methods, the effect is most ideal, this is the trend in recent years, domestic and grinding system design. Three relationships: Before the crushing mill is a prerequisite, Dalian mill, separator after grinding is to ensure that the mill is a fundamental transformation. Before crushing mill into the ground so that particle size is greatly reduced, thereby reducing the load on the grinding system; separator efficiency, ball mill parts, the most direct benefit is the maximum fine be finished in time chosen, mill equipment, reduce cement finished products back to the extraction rate, reduce the mill load; the mill renovation, which is to improve the grinding system is the most fundamental solution. 1.2 Quality of cement quality cement, just from the grinding process, the grinding broken and the front separator efficiency is not directly related. China's cement quality inspection indicators are generally two: the residual value of cement sieve and specific surface area. But in recent years the international cement quality test indicators on the cement particle size distribution, and, this indicator than the residual value of cement sieve and specific surface area to better reflect the real situation of the quality of cement. Second, the meaning of our mission is to implement the new standards must significantly improve the quality of cement products, further meaning is to accelerate the elimination of backward, to promote market competition, with the international cement standards for the cement industry after China's accession to WTO to prepare for integration into the international market . As a result, mill power, China's cement plant, especially small and medium cement how to improve the yield and quality of cement, has become an urgent problem.
