Get Price### ball mill critical speed processing & metallurgy

a ball mill critical speed (actually ball, rod, ag or sag) is the speed at which the centrifugal forces equal gravitational forces at the mill shell's inside surface and no balls will fall from its position onto the shell. the imagery below helps explain what goes on inside a mill as speed varies. use our online formula the mill speed is typically defined as the percent of the theoretical

to make the mill more efficient, some roll mills are equipped with a system allowing to guarantee a high pressure (10 50 bar) in between the rolls. it is also mandatory for these mills to have a spring system allowing to release the pressure if the constraint is too important ( foreign body for example) and avoid mechanical damages.
