A magnetite bearing ore is liberated in a milling circuit prior to concentration; the circuit consists. of a ball mill, a discharge sump and a slurry pump followed by a hydro - cyclone classifier. Fresh. ore that is fed to the mill has a moisture content of 5 % and consists of 8 5 % of class 1 ( dry basis)
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 tonnage on tons/day or tons/hour.
