Section snippets Materials used. An antimonial refractory gold/silver ore sample obtained from Akoluk (Ordu-Turkey) was used in this work. The ore sample was crushed down to − 4 mm using jaw and rolls crushers, and riffled to obtain 1 kg representative sub-samples.These were then ground in laboratory rod mill at 50% pulp …
How Ball Mill Ore Feed Size Affects Tonnage & Capacity
Hard ore Work Index 16 = 100,000/65,000 = 1.54 kwh/t. For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons ...

Ball Mill (Ball Mills Explained)
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.
