摘要
Materials on and the results of testing new types of equipment for producing grinding balls of high surface hardness and normalized volume hardness are presented. The EVRAZ NTMK company has implemented a technology of producing grinding balls of high strength, including of hardness group 5 (high surface hardness and normalized volume hardness), according to GOST 7524–2015. For this purpose, a set of equipment for producing grinding balls and testing them for impact resistance was put into operation. Meeting the requirements allows achieving high service characteristics of grinding balls.
