Abstract

The parameters of over 40 various types of milling bodies developed or manufactured by domestic and foreign manufacturers are analyzed. It is established that the wear resistance of ceramics depends on two groups of factors: external ones (process characteristics, design specifics of milling machines, shape and size of milling bodies) and internal ones (structure parameters, composition and properties of materials). The structure of ceramics has a deciding effect on the wear resistance of materials of the same type. Wear resistance can be increased by increasing the corundum content in the mixtures or by controlling the microstructure of ceramics by introducing modifying additives. Additives of eutectic compositions are the most promising.
