sible to shorten the time of iron ore inside a ball mill, the ball mill output grows as a result, and a larger size product is obtained. The grain size required for pelletizing is reached in further HPGR grinding (Fig. 5). In so doing, en-ergy consumed by milling, ball mill wear and power taken by filters are reduced.
A comparison of the grinding media is given together with the knowledge gaps that still need to be bridged to improve the quality and performance of grinding media used in ball mills.
In the previous discussion the fact was established that the work done by a ball when it strikes at the end of its parabolic path is proportional to its weight and velocity; then, since the velocity may be considered as constant for all the balls in the mill, the work done by a ball is proportional to its weight. Since the amount of ore crushed varies as …
