    Fine grinding of brittle minerals and materials by jet mill

    The Mount Isa Lead-Zinc Concentrator Tower mill is used for fine grinding of fine grain particles near the tail of the circuit. It had a similar performance in both the LGM circuit (Table 3) and the current zinc retreatment circuit (Table 4). The circuit operating (mill+cyclones) index was low in both applications suggesting efficient size reduction.Mar 01, 2018 Due to imperfect classification, particles accumulate inside the mill which is further enhanced by a high holdup of fine particles. Our results clearly show that the classification and transport processes must be studied in detail for any in-depth understanding of dry fine grinding in fluidized bed opposed jet mills.
