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 ...

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.

The wet ball mill has two types as follow: grid type and overflow type.The grain size limit of the grinding mill is usually 0.2 ~ 0.3mm, so it is commonly used in the first segment. The particle size of the grinding mill is generally less than 0.2mm, so it is suitable for the second grinding of the middle product in the two-stage grinding process.
