WhatsApp: +86 18203695377Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.
WhatsApp: +86 18203695377Bond work index: Wj= kWhlshort ton From Eq. (6), the specific grinding energy is: W = kWhlshort ton or W = kWhlt For throughput 400 tIh production, the total required ballmill power is: kWhlt x 400 tIh = 34092 kW. If six (6) ballmills are used, the power drawn from each mill is: (34092/6) = 5682 kW.
