Oct 09 2015 Calculating a grinding circuits 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.Pulp samples collected around the ball mill or rod mill and hydrocyclones screen or .
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
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 PSD; then circulating load can also
Ball Mill Circulating Load Calculations. Vrm and ball mill circulating load - page 1 of 1.Sep 07 2011 re vrm and ball mill circulating load.Mainly in usa the term circulating load is more often used than the circulation factor.Circulating load is percentage of coarse return in relation to fines it can be calculated by coarse return tph x 100 mill output tph.Normal range of cirulating load .
The ball mill has higher circulation load it generates only 30 -35 of actual fines you require to be called as product. If your product size needed is 100 passing 45 micron then the ball mill total discharge material will contain normally 30 of 45 micron. The rest is oversize which has to be ground again.
