Abstract Ball drum mills (BDM) are one of the main types of coalgrinding equipment in Russia. A significant drawback of BDM is high power consumption (a significant part of the TPP's own needs). With a huge scale of production, reducing these costs even by a few percent gives a significant economic effect. The problem of minimizing the specific energy consumption for grinding and ...

Influence of the milling ball filling degree. Figure 2 illustrates the change in the temperature progression, if the milling ball filling degree Φ MB is varied. An increase of Φ MB from to resulted in a higher end temperature and heating rate, whereas the differences in T milling bed for ≤ Φ MB ≤ are small compared to experiments at higher filling degrees (for ...

Figures 5 and 6 respectively. Accurate measurements of the ball filling can only be made after the mill is ground out. In this case the mill is operated with the feed turned off until all of the ore has exited the mill. Measurements of the ball level within the mill can then be made. Figure 7 shows an example of the balls in a mill after a ...
