Methodology And Design Of Ball Milline

In a discrete element method simulation of theinside of a ball mill, the coefficient of friction of theballs is the most important factor, and it has beenreported that the spring coefficient and damping coef-ficient calculated from Young’s modulus and Pois-son’s ratio do not have a large effect on the ballmotion.9)There is correlation between the coefficientof friction and grinding, and with gibbsite

    Applications of a new model-based method of ball mill

    Abstract The multi-segment ball mill model developed by Whiten and Kavetsky has been used together with an extensive range of data from operating mills to establish the parameters of a new ball mill model suitable for simulation and design of coarse grinding ball mills (i.e. mills containing some plus 2mm particles in the mill discharge). The model incorporates an ore-specific breakage
