Read MoreMay 08, 2017 If now the material undergoing grinding occupies the spaces between the balls of the ball charge, it follows that the centre of gravity of the powder mass will coincide with that of the ball mass. Thus, if the mill charge retains the same configuration as it has when balls only are present, that is, the configuration is unaltered by the inclusion of the powdered material, then it follows that the torque to drive the mill will be proportional to the total weight of the charge in the mill.
Read MoreLet radius of the mill = R radius of the ball = r The distance from the centre of the mill O and the centre of the ball (R r) while is the angle between the vertical and the radius AO. At A two forces are acting on the ball (1) Force of gravity (2) Centrifugal force (1) Force of gravity As we know that F = mg for horizontal plane but here it is.
Read MoreThis ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types grid type ball mill and overflow type ball mill.
