Advances in screening technology in the mining sector
If the hydrocyclone or screening machine has a low selectivity, so that the unit or machine is said to have an efficiency of only e.g. 70 – 80 %, this means that 20 – 30 % of the coarse material gets into the fines, or 20 – 30 % of the fine material is returned to the previous process step (grinding or crushing process).
