Solid Mineral Mining Equipment

Why is the Solid Mineral Mining Equipment grinding roller seriously worn?

In the process of processing stone, Solid Mineral Mining Equipment grinding roller and grinding ring are the most vulnerable parts. Although the material of these wearing parts has been continuously updated, it still cannot meet the processing of some high hardness materials, although The wear of the grinding roller is normal, but some customers’ wear rollers will wear out prematurely. Therefore, it is necessary to find out the cause and prescribe the right medicine. Below we analyze the common situation.

Quality of casting

At present, most of the grinding rolls are integrally cast, and the inner hole structure is not very reasonable. The integral grinding roller is too thick at the time of casting, and it is easy to cause cracking and looseness due to uneven cooling. At the same time, the grinding roller is formed by integral casting, and its wall thickness is thick. When pouring, the interior is slower than external cooling, which is also likely to cause uneven cooling and cracking, shrinkage, and porosity.

Roller material

The more commonly used grinding rolls on the market are made of high manganese steel and high chromium cast iron. Because the as-cast microstructure of high manganese steel is very brittle, the mechanical properties are not high after solution treatment, and the hardness is also low, so its service life is relatively low. High-chromium cast iron is an excellent anti-wear material with strong wear resistance and toughness. It also has good resistance to high temperature and corrosion, making it a common choice for grinding rolls.

Through the above analysis, it is not difficult to see that the biggest cause of excessive wear of the Solid Mineral Mining Equipment roller is the quality of forging, so it is necessary to buy good equipment or accessories. SBM mainly produces mills and accessories. Our company can stand the test of both the accessories and the quality of the equipment. You are welcome to inquire.
