2012.3.6 The heat-treated balls were tested simultaneously at three factories in industrial grinding mills. The tests showed that the Russian-made grinding balls are the equal of their foreign (French) counterparts in terms of wear resistance. Their wearability over 50 h of service was 0.4%. Thus, after 1 h of service their wearability is 0.008%.
