Get PriceA 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 be calculated
