Wet grinding experiments conclude that 30 min of grinding time, 350 rpm speed, water addition of 50% (w/w), and 2 mm grinding media results in achieving the fine-sized coal slurry with an average particle size of 45 μ and total undersize less than 75 μ. It was observed that direct centrifugal separation at 50% pulp density can result in ...

In the Ultra Centrifugal Mill, grind-ing takes place by impact and shearing action between the rotor and the fixed ring sieve. The feed material passes through the funnel with splash-back protection onto the rotor. The centrifugal accele-ration throws it outward with great energy and it is pre-crushed on impact with the wedge-shaped
