AMIT 145: Lesson 2 Classifying Cyclones – Mining Mill
Classifying cyclones are the most commonly used technology for achieving particle size separations below 300 microns Classifying cyclones are comprised of a cylindrical section and a conical section The length of themill circuit (Figure 1), this is achieved by taking a sample of cyclone underflow and a sample of ball mill discharge, and then running a screen analysis in the lab For forward fed circuits (eg primary ball milling), a size distribution of the combined mill feed (circuit new feed and c yclone underflow) is required While not asA guide to maximising ball mill circuit classification system
