Use this Equation & Method to properly grind your ore.Experimental Study on the Grinding Rate Constant of a Ball ...We investigated tlte effects of ball diameter and feed size on the rate constant when the ball mass, feed mass, and the mill's rotational speed were constant. The results indicated that the grinding rate constant can be expressed by modifying the equation that was proposed by Snow as the function of ball diameter and feed size. 1.Ball Mills - an overview | ScienceDirect Topicswhere d b.max is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m).. Generally, a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.
