The fineness grinding dependence on the grinding media size

Aug 16, 2018 · The fineness grinding (the grinding quality) depends on the ratio the grinding media surface area (S) to grinding media volume (V). The greater this ratio value means the greater fineness grinding, i.e. more qualitatively grinding. The following table summarizes all physical and geometrical data of the most commonly used grinding media.
