(SiO 2) obtained from the survey of an industrial ball mill magnetite grinding circuit. The size separation for silica is much coarser, with a d 50c for Fe 3 O 4 of 29 μm, while that for SiO 2 is 68 μm. Due to this ... In the same period, closed-circuit has larger production rate. However the disadvantage is that the production flow of closed-circuit is more complex, and costs more than open-circuit grinding. Nonconforming materials are repeatedly ground in the closed-circuit grinding phase until a qualified particle size is reached.
