sonable to replace, totally or partly, ball milling for HPGR wet grinding after filtering. This substitution makes it pos-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).
