More DetailThe spring coefficient Kn in the normal direction is given by the following equation using the Young’s modulus E of the ball and the mill wall and Poisson’s ratio and using the Hertz theory of elastic contact The subscripts i j and w indicate the balls i and j and the mill wall Eq 3 Eq 4 Eq 5 Eq 6 Eq
More DetailThe following equation is used to determine the power that wet grinding overflow ball mills should draw For mills larger than 33 meters 10 feet diameter inside liners the top size of the balls used affects the power drawn by the mill This is called the ball size factor S Rod and Ball Mills by CA Rowland and DM Kjos AllisChalmers
More Detail1 Calculation of ball mill capacity The production capacity of the ball mill is determined by the amount of material required to be ground and it must have a certain margin when designing and selecting There are many factors affecting the production capacity of the ball mill in addition to the nature of the material grain size hardness density temperature and humidity the degree of
More DetailThe ball sizing formulas from the literature on ball diameter selection do not take into consideration such as the target P90 Based on his work this formula can be derived for ball diameter sizing and selection Dm 6 log dk d05 where D m the diameter of the singlesized balls in mmd the diameter of the largest chunks of ore in the mill feed in mm
More DetailThis equation produces a maximum in S and the particle size of the maximum is related to ball diameter by xm k1d2 The variation of a with ball diameter was found to be of the form a k2d15
