A new procedure for Tower mill simulation and scale-up has emerged recently. Introduction The Tower mill is a vertical stirred grinding mill which can be used in both dry and wet grinding applications. It has provided a means of size reduction in an area where conventional tumbling mills become inefficient (Morrell et al, 1993). The major advantage of the Tower mills over the ball mills
