Choice of ball mill liner material

　　If the work efficiency of the ball mill is high, one of its key issues is: How to select a good ball mill liner material. The ball mill is different from the mineral mode, can be laminated and overflow type. The ball mill can be divided into a short cylinder mill, a long cylinder mill, a tube mill, and a conical mill. The ball mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metallogenicity and glass ceramics and other production industries, dry or wet grinding of various ore and other wear materials. .

　　Because the ball mill liner is not only to withstand the impact and wear of the grinding body, but also the role of enhancing the grinding body. Therefore, the mass of the ball mill liner material has a pivotal role in the work efficiency of the ball mill. Used in cement (material: powdered hydraulic inorganic gelling material), the ball mill is mostly long diameter than L / D> 2.5, which is not stranger for this point. The mill has a coarse mill and a fine grinding (some of the three warehouse), and their role is different. The coarse grunge is mainly broken, and the fine grinding warehouse mainly plays grinding. The base plate of the coarse grinding cartridge is mainly based on the stepper liner and the wavelength liner, and the liner of some new high-efficiency energy-saving mills is not departed from their basic form.

　　The fine mill is mainly in the form of a pattern liner, a small corrugated liner, a flat liner. Due to the different effects of the coarse grunge and fine grinding bins, the push of the carrier is different, and the impact force of the liner formed is also very different. The abrasive body diameter of the same mill diameter is large, the material block is also large, the impact of the liner is large, and the velocity of wear is high. The case of fine grinding bin is much better! When selecting a liner material, different materials must be determined according to different conditions! The liner materials currently applied in extensive are mainly three types: Manganese Steel: Applications Quite extensive, but most of the case is limited to impact, it is easy to deform, and the medium alloy wear-resistant steel: has better wear resistance, based on silicon, add chromium, etc.

　　Other trace elements, its wear resistance is better than high manganese steel, but there is also a certain drawback, such as hardenenability, insufficient high-chromium cast iron (CAST IRON): there is a lot ofThe 20% high-hardness eutectic carbon (C) is high in wear resistance, but there is a high production cost, therefore, the choice of ball mill liner material is to be considered in combination with the Composite factor (Factor). The purpose of simplicity of simple process, low cost, high hardenability, and environmentally friendly (high) energy-saving ball mills.

　　The ball mill is suitable for dust grinding various ore and other materials, which are widely used in different industries such as moisture, building materials and chemicals, can be divided into dry and wet two kinds of grinding methods. The ball mill is different from the mineral mode, can be laminated and overflow type. Engaged in energy-saving ball mills, ceramics (raw materials: non-metallic minerals) ball mills, cone ball mills, etc. Quality quality, perfect after-sales, escort your equipment and production!
