If the ball mill is high, one of its key issues is: How to choose a good ball mill liner material. The ball mill differs depending on the mine 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, etc., 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 pivotable role in the work efficiency of the ball mill. For cement (material: powder hydraulic inorganic gelation), the ball mill is mostly long diameter than L / D\u003e 2.5, which believes that everyone is not unfamiliar. The mill has a coarse grinding bin and a fine grinding bin (some 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 wavefront, and some of the new high-efficiency energy-saving mills are 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 grunge, the pilot of the carrier is different, and the impact force of the liner formed is also very different. The abrasive body diameter of the coarse grindstone mulga of the same mill is large, the material block is also large, the impact of the liner is large, and the 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 material currently applied in extensive is mainly three types:
high manganese ( Manganese: Extensive, but most of the case is limited to impact, easy deformation
low, medium alloy wear-resistant steel: has better wear resistance, silicon ( Silicon is based, add other trace elements such as chromium, which wear resistance is better than high manganese steel, but there is also a certain drawback, such as hardenenability, lack of quenching
high chromium cast iron (CAST IRON): which contains no less than 20% of high-hardness eutectic carbon (C), high wear resistance, but there is a high production cost
Therefore, the choice of ball mill liner material, Considering the Composition Factor (Factor) to achieve simple process, low cost, high hardenability, and environmentally friendly high-efficiency (high degree high) energy-saving ball mills. The ball mill is suitable for polishing various ore and other materials, which are widely used in different industries such as mineralization, building materials and chemicals, can be divided into dry and wet-forming milling methods. ballThe mill is different from the mineral mode, and can be laminated and overflow.
