The materials used for grinding balls


cast grinding ball

The ball mill uses a large amount of Grinding Balls. China's annual consumption of grinding balls is more than 1 million tons. Therefore, the materials used for grinding balls have always been concerned.

High-chromium cast iron is the best cost-effective wear-resistant material at present. It is mainly used for dry grinding in the use of grinding balls. As long as its corrosion resistance and toughness are further improved, it is possible to make grinding balls suitable for dry and wet grinding conditions. How to improve corrosion resistance and toughness, chromium manganese tungsten anti-wear cast iron technically solve this problem.

Chromium-manganese-tungsten anti-wear cast iron on the basis of high-chromium cast iron, increase the manganese content, replace the chromium in the carbide with manganese, transfer part of the chromium in the carbide to the matrix, thereby improving the corrosion resistance of the matrix, adding tungsten to the crystal Grain refinement, increase the hardness point to improve the toughness, and the simultaneous addition of manganese and tungsten improves the hardenability of the material, and the toughness and corrosion resistance are ensured by proper heat treatment to ensure the material has excellent wear resistance.

Compared with the traditional detailed ingredients, the high-chromium white-mouth cast has a certain improvement. By adjusting the chemical composition of Cr--Mn-W anti-wear cast iron, the heat treatment process is further optimized, and a material that can adapt to the grinding of the dry and wet mill is sought.
