torque factor of ball 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.

Aug 10, · After reviewing the results, Valley Forge engineers determined the mill’s maintenance staff needed a method of monitoring bolt tension so they would have some warning of emerging issues. Engineers also wanted to extend the grip length of bolts used in the ball mills.

the mechanical factors affecting the ball mill output. factors and solutions affecting the output of ball mill seven factors affecting the output of ball mill Particle size of grinding materialsBecause the shaft kiln cement factory uses the ball mill specifications are generally small, so, into the size of the grinding material size of the mill production, quality impact is very big, small

The DEM results are shown to be highly consistent with the experimental results. The torque of liners and baffles are affected by lifter height, lifter number, and mill speed. Moreover, the changes in the torque and power consumption of a ball mill can be effectively explained using two important factors: lifter and particle area ratio.
