  • Difference Between Sag Mill vs Ball Mill -

    The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially. Interior of the drum uses the lifting plates. These plates inside the drum are responsible for picking the grinding material up to fall down again throughout the rotations. Repeated collisions between the steel balls and raw materials (ore

  • Electromechanical Dynamic Behaviour and Start

    Power factor 0.857: Stator and rotor connection At =6 s, =7 s, and =8 s, the electromagnetic torque is less than the load torque of the ball mill during the friction process. This variation is shown in Figure 7. This condition corresponds to the decrease in the rotational speed in Figure 4. Similarly, the electromagnetic torque is two times less than the load at =9 s and =10 s. Therefore

  • TECHNICAL AND COMMERCIAL BENEFITS OF GEARLESS MILL

    general, the bigger the mill diameter, the lower are the mill operating and critical speeds. Thus, for larger mills the number of poles will increase. As a result, the number of poles can vary from 48 to 72 poles (Fig. 3.) with typical mill speed requirements of about 10 rpm for larger SAG mills and about 15 rpm for smaller ball mills. Figure 3.
