When the ball mill load is low, the motor can be put into 3, 2, or 1 module for operation, and the torque distributed equally to each module is 4/3, 1.5, or 4 times that of the original. Obviously, the efficiency will be increased when the number of operating modules at low load (torques at the same speed) is reduced.
Design of the kubaka grindng circuit using spi and . the kinross kubaka project is a gold mine located in the russian far east. the grinding circuit comprised of a 6.1 m diameter x 2.74 m long sag mill and a 4.1 m diameter x 5.5 m long secondary ball mill in closed circuit with cyclones was built using sag power index and bond ball mill work index testing to determine the grinding energy.
