The magnets are located inside the liquid-filled drums, where magnetic particles are drifted with movements. The basic method is usually used in iron ore beneficiation. Grinding. Grinding is a standard beneficiation process that reduces the mineral size by mechanical forces breaking the structural bonds.
Mechanical grinding reduces particle size, which can impact packing density and nucleation, and has been reported to decrease crystallinity in some cases . Through this, grinding has been proven to improve mechanical strength and chemical/environmental resistance of cement [10], [12], and the resulting materials can even behave comparably to ...

Ore Crushing and Grinding. Ore crushing and screening, grinding and classification are essential preparatory work before separation to get proper ore size. There is a balance to keep proper ore size neither too rough (insufficient liberalization) and too fine (over-crushed) in order to achieve high recovery rate and high efficiency.
A typical grinder of 45 Mg/hr (50 ton/hr) capacity will discharge about 1.6 to 2.5 dry normal m3/sec (3,500 to 5,500 dscfm) of air containing 1.14 to 11.4 g/dry normal m3 (0.5 to 5.0 gr/dscf) of PM. The air discharged is "tramp air," which infiltrates the circulating streams.
