Design considerations for large diameter ball mills . Large mill (D> m ( ft)) performance has been successfully predicted from small scale batch experiment for grinding kinetics and an RTD correlation for transport using population balance effect of ball size must be properly taken into account in the scaleup.
Large mill (D> m ( ft)) performance has been successfully predicted from small scale batch experiment for grinding kinetics and an RTD correlation for transport using population balance effect of ball size must be properly taken into account in the scaleup. A design method that combined the kinetic scaleup findings and the transport of material through the mill has been ...
