    Jul 31, 2003 The motor drives a cement ball mill, and the operator is blaming the starter but I think that if it is not accelerating as it used to then the load has increased. Any thoughts? Also the starter used soda ash (sodium carbonate) to modify the conductivity fo the water, does any one know what the chemistry of the liquid should be?

    Sep 15, 2013 For example, If the stator full load current was 250A (not sure what it is in this case) and the Stator start current was 400A (1.6x) then I would expect Rotor start current to be 1.6 x Rotor full load current = 775 x 1.6 = 1240A. Torque delivered would be around 1.6 x Full load torque, very typical for a ball mill or sag mill as Chris mentioned
