The ball mill is key equipment for re-crushing materials after being primarily crushed. It has been widely used in a wide range of manufacturing industries such as cement, silicate, new type building materials, fireproofing, chemical fertilizer, black and non-ferrous metal and glass ceramics.
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 per day.
