Ball mill rotating speed when grinding ball adding rate remains constant the useful power of ball mill varies with the rotating speed therefore production efficiency will also be influenced. Ball mill rotating speed need to be adjusted according to different types of ores. grinding media consumption accounts for 6590 of the total
Scaleup of power consumption in agitated ball mills Consequently a method had to be found of introducing power into the mill so as to obtain a given specific energy input. For this purpose stirring tests with purely Newtonian liquids were carried out in absence of solids and hence without comminution.
