Hardwearing grinding balls – grinding balls with high surface hardness and normalized volumetric hardness. This is mainly grinding balls the fifth hardness group with lower specific consumption in comparison with balls the 2th – 4thhardness groups. Requirements to grinding balls regulated by DSTU 3499-97, DSTU 8538-2015 (GOST 7524-2015).
