screen circulating load calculation

A simple one - ball mill w/ hydrocyclone. I observed that the most common methods applied are (1) use of water balance - taking samples of cyclone feed, cyclone underflow and cyclone overflow. They will get the %solids, then compute for dilution ratio - then finally, %circulating load. and (2) use of particle size distribution - the samples taken for %solids will be screened for …

ball mill circulating load - mineral processing & metallurgy

Oct 09, 2015 · Calculating a grinding circuit’s circulating loads based on Screen Analysis of its slurries. Compared to %Solids or Density based Circulating load equations , a more precise method of determining grinding circuit tonnages uses the screen size distributions of the pulps instead of the dilution ratios

circulating load calculation formula

Feb 21, 2015 · Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating load ratios and circulating load …
