Stainless steel ball hardness is too high for grinding

When choosing a stainless steel ball, two problems are often overlooked: the stainless steel ball is not as hard as possible, but has its proper hardness value; stainless steel ball density is also a problem that cannot be ignored. Regarding the influence of hardness, generally speaking, as the hardness increases, as long as no breakage occurs, the single-piece consumption of the stainless steel ball is lowered; and the deformation of the spherical body is small, and the deformation of the spherical body is small during the crushing, and the energy can be more used for crushing the ore particles. The productivity of the mill can be increased. However, the increase in the hardness of the stainless steel ball can only be moderate, and there is an appropriate range, not the harder the better.

If only the ball consumption is considered, the higher the hardness, the lower the consumption. However, for the mill productivity, the productivity increases with the increase of the hardness of the stainless steel ball within a certain range, but when the hardness exceeds a certain range, the mill productivity is adversely affected, and the mill productivity is lowered.
