High-chromium steel balls are made by adding trace elements such as gold, chromium, manganese to the original chemical composition, using advanced technology such as anhydrous resin sand molding and oil quenching heat treatment to produce good toughness High performance wear resistant steel ball with high wear resistance.

At present, most of the grinding media used in cement industry are high-chromium balls. With the continuous development of cement grinding technology, the specific surface area and fineness of cement are required to be even higher. As a cement company, the correct selection of grinding materials is particularly important.

hardness of grinding balls was done with a hardness testing machine. A mathematical model was also developed using MATLAB 2010 to determine ball wear rate for the grinding balls. To determine the optimum Cr/C ratio that brings the best hardness for the balls The chromium/ carbon variations were done by

Cast grinding balls are solidified in high chromium cast iron to form (CR, Fe)7C3 type carbides, which are discontinuous in the structure, so they have much better toughness than ordinary white iron. In addition, the microhardness of (CR, Fe)7C3 is much higher than that of (Fe, CR)3C carbides in common white iron, and it exceeds the hardest abrasive material commonly …

Recently, chromium grinding balls manufacturers generally use metal, graphite, lost foam dry sand vacuum modeling more. 1) Metal type.
