The hardness of grinding media ball how to choose balls

But for the productivity of the ball mill, the productivity increases with the increase of the hardness of the ball in a certain range, but when the hardness exceeds a certain range, the productivity of the mill decreases. When the hardness of grinding media ball is too high, there are two unfavorable reasons for grinding

Volumetric hardness of grinding balls energosteel

Volumetric hardness of grinding balls — a calculated index of hardness. It summarizes hardness value for the grinding ball volume. The calculation formula: VH= 0,289 Тsurf+ 0,436 Т0,25 + 0,203Т0,5 + 0,063Т0,75 + 0,009 Тc

Cast Grinding Steel Balls 911Metallurgist

Secondary Grinding Ball Mills In secondary ball milling, abrasive and corrosive conditions predominate. The smaller balls [< 2½”, (65 mm)] typically used in secondary milling environments effectively reduce the impact component of wear to the point where grinding media must be primarily designed to reduce abrasive and corrosive wear.
