Through the production of roller press studs (HPGR) by precision casting, which is less costly than the manufacturing process currently used, we work on reducing the wear of the studs and the operating and maintenance costs of the HPGR roller press. In another initiative, we have developed steels with higher impact and wear resistance than conventional materials currently used for the segments of the MSR roll crusher designed to the fragmentation of jaspelite ore with increasing the useful life of the segments. Another project offers support and improvements in the process of changing belt conveyor idlers and other maintenance demands.
