The advent of sand making machine helps the processing technology of gravel industry make a big step further. The sand maker not only can satisfy the construction requirements of each project in quality and quantity, but also can adapt to the requirements of mechanized construction. However, because of its special working conditions-being exposed to the sunshine and wind for long time, and the machines’ own problems, the problem of low efficiency appears, which affect the normal production, causing huge losses to investors. Therefore, how to resolve the excessive abrasion of sand making plant is particularly important. The quick-wear parts of sand maker usually include board hammer, impact liner, enclosure liner and the liner of rotor body and so on. Among these parts, the board hammer is easily worn and the cost is higher. Thus, lessening the wear of the board hammer is the key to solve the problem of sand wear.
The first factor is the nature of material, whose influence on the board hammer includes the nature of the material, the particle size of the feedstock and its water content and other factors. The nature of the material is the factor that has largest impact on the board hammer. There is a big difference of unit pure wear of board hammer among different materials.
The second factor is the influence of processing capacity and the discharging gap. When the processing capacity is increased, product size will be thicker, broken ratio decreases and the unit pure abrasion of the board hammer becomes lower at the same time. The size of discharging gap, to some extent, can also change the thickness of the product particle size, having a certain influence on the wear of board hammer.
The quick-wear parts of the sand maker produced by Hongxing Heavy Industries adopt the most advanced double metal composite with good wear-resistance. Because of its good performance, the device has been widely used in the production of glass, quartz sand and other high purity materials in order to meet the requirements of industrial production.
