Hence, typical gold or copper ore requires between and kWh per ton of energy to reduce the particle size. ... A research team from the University of Utah is working to make inroads into saving energy in these SAG mills. In 2003, .
WhatsApp: +86 18203695377WEBPrinciple 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.
