The service life of grinding balls is affected by many factors, and there is no fixed duration. Today, let's learn about the service life of grinding balls of different materials.
① Ceramic grinding ball
Performance characteristics and service life range: ceramic grinding ball has the characteristics of high hardness and good wear resistance. For example, the hardness of alumina ceramic grinding ball can reach HRA85- 90. Under general laboratory grinding conditions, if it is used to grind materials with low hardness, such as some common ores and powders, its service life can reach hundreds or even thousands of hours. However, if it is used to grind materials with high hardness, such as silicon carbide, its wear speed will be accelerated, and it may need to be replaced within tens of hours to hundreds of hours.
Influencing factors: the quality of ceramic grinding ball has a great influence on its service life. The high-quality ceramic grinding ball has a compact internal structure, without obvious pores and impurities, and can effectively resist wear. In addition, the pH in the grinding environment will also affect its life. If the ceramic grinding ball is grinded in an acidic or alkaline environment, chemical corrosion may occur, resulting in a decline in surface quality and a shortened service life.
② Stainless steel grinding ball
Performance characteristics and service life range: stainless steel grinding ball has good toughness and can withstand impact to a certain extent. For the grinding of some less hard materials, such as food and plastic, the service life of stainless steel grinding ball may be about several thousand hours. However, the hardness of stainless steel is lower than that of ceramics. When grinding materials with higher hardness, the wear will be obvious, and the service life may be only a few hundred hours.
Influencing factors: the material composition of stainless steel grinding ball (such as chromium and nickel content) will affect its corrosion resistance and hardness, and then affect its service life. At the same time, in the grinding process, if it rubs with other metals to produce electrochemical corrosion, or contacts with highly corrosive substances such as chloride ions, its service life will be greatly reduced.
③ Agate grinding ball
Performance characteristics and service life range: Agate grinding balls are hard and smooth. They are suitable for grinding samples with high purity requirements, such as some high-precision drugs and optical materials. When grinding soft materials, agate grinding balls have a long service life, which may reach thousands of hours. However, due to its high brittleness, agate is easy to crack when grinding materials with high hardness or under large impact, and its service life will be significantly shortene.
Influencing factors: the quality and purity of agate grinding ball are very important to its service life. Agate grinding balls with high purity and no obvious cracks have a longer service life. In addition, the grinding method will also affect its service life. If there are frequent collisions and drops during the grinding process, the agate grinding ball is easy to be damaged.
