Fine Dry Grinding of Iron Ore for Pelletizing

Jun 20, 2019  In open circuit grinding, the size distribution and the specific surface of the product is controlled primarily by varying the feed rate, depending on the nature of the ore, and thus control is somewhat limited. The installation of a classifier in a closed circuit with a grinding mill offers additional control by the adjustment of the classifier.
