Flexible drive solutions for use in ball mills A ball mill is a horizontal cylinder filled with steel balls or the like. This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls.
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.
of the inching reducer drive can be added to reflect efficiency losses. P inch = P inch ·(1 + (stage · 0.01)) where stage is the number of reductions between the inching drive motor and the main drive input shaft (or mill pinion if direct driven) Round up P inch to the next standard motor power. This standard motor power becomes the incher ...
