The mill used for this comparison is a 4.4-meter diameter by 13.6 meter long ball mill with a 5000 HP drive motor. It is designed for approximately 90 s.ton per hour. This type two-compartment mill is a state- of-the-art shell supported cement finish mill. The torque and time requirements of the mill with the ball

The other fascinating issue is that this ball mill is apparently not a truly constant torque application, as the torque increases with the speed from about 70% of rated torque at 10% rated speed to rated torque at

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed ...

Meanwhile, the torque is roughly inversely proportional to the lifter height when ψ = 100 % (except for the curves of the torque corresponding to H l = 0 mm and H l = 3 mm in Fig. 19d) because the particle area ratio becomes the decisive factor when a ball mill rotates at a high speed. The particle area ratio is high when the lifter height is ...

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.
