What should be noticed when designing the wear-resistant materials used in ball mill, tube mill and other equipments? .these are summarized in the following reference:
1, the abrasive material
The abrasive material refers to a variety of equipment, delivery of granular or powdered materials. The abrasive material covered by the cement plant limestone, clay, sandstone, iron ore, iron, bauxite, cement clinker, all kinds of mixed wood, plaster and cement, and these abrasive material particles by the physical shape is divided into shaped and powdered abrasive material.
2, abrasive objects
The abrasive objects - that is contact with the abrasive material and with the occurrence of the relative motion of various equipment components. A wide range of cement plant equipment, both equipment manufacturer in accordance with the countries or companies to develop the appropriate equipment standard manufacturing of standard equipment, including a variety of pipes, silos, downpipe is individually designed according to the form of a process layout manufacturing, on-site production standard equipment.
Parts of the equipment according to their state of motion can be divided into parts sports equipment and parts movement of equipment, parts movement of equipment referred to as dynamic device, parts movement device is referred to as static equipment, parts movement in the form of linear motion and circular and other sports.
Parts of the equipment according to their metal wear-resistant material is divided into a wear-resistant parts and non-wear parts, so the choice of wear-resistant materials can be divided into the choice of wear-resistant parts metal wear-resistant materials and non-wear parts wear resistant protective layer grinding material selection two categories.
3, wear-resistant materials
The main points are metal wear-resistant materials, ceramic wear-resistant materials, wear-resistant polymer materials, wear-resistant composite materials, and wear-resistant material according to the nature of the material itself.
The wear-resistant metal material mostly used in the dynamic device's moving parts as well as serious internal wear parts are abrasive object itself, in order to reducing the wear of the abrasive objects. Such as: mill liners, ball, hammer crusher board hammer, jaw plate, roller, disc, roller and grate cooler grate and so on.
