AMIT 135 Lesson 7 Ball Mills Circuits

Mill Type Overview Three types of mill design are common The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns The Center-Periphery Discharge mill has feed reporting from both ends and the product discharges

A Method of C alculating Autogenous/ Semi

stage ball mills rod mills or AG/SAG mills when calculating power according to the Bond Third Theory method Rod mill and AG/SAG mill products are similar and tend to be not as steep as a 0 5 slope when plotted on log-log paper This is because the particle size distribution (PSD) these mills produce have a coarse fraction but also a fi ne fraction which is not credited for in an 80 per
