In placer tin ore, the gravity separation process is: screening – jigging – dehydration；. For placer tin ore with a low monomer dissociation degree, it often needs to go through two gravity processes: screening – jig, rod mill – jig – dehydration；. Tin processing of gravity separation is based on the principle of gravity ...

Therefore, to evaluate the quality of the grinding machine, we must refer to these factors: productivity, energy consumption, over-crushing rate, etc. When the ore grinder does not have grinding action, r=r 1, r 3 =r 2, and E efficiency =0 from formula 1. When all the ore has been crushed, r=, r 3 =, and E efficiency =0.

A moderate removal rate of Q = 50 mm 3 /s over a 25-mm wide cut is quoted as Q′ = 2 mm 3 /s per mm width or 2 mm 2 /s equivalent to 0.186 in. 2 /min in British units. In HEDG, a possible removal rate as high as Q = 1200 mm 3 /s over a grinding width of 2 mm translates to Q′ = 600 mm 2 /s (or 55.8 in. 2 /min).

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
