4.1k. Posted July 17, 2015. First, there are a few ball mill incidents each year but very few compared to the number of ball mills producing powder at any time. Second the damage is smaller for a small mill or the other way round it's a disproportionately excessive crater for a bigger mill -use a small mill.
عرض المزيدThe ball mill is the key equipment for crushing materials after they have been crushed.

عرض المزيدCrushed 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.
