Model-based procedure for scale-up of wet, overflow
网页2001年10月1日It is the most popular and successful of the power-based methods for bail mill scale-up. It calculates the mill power required to grind a specified throughput rate of ore from a given feed 80% passing size (p80) to a given product p80. This calculation needs the Bond Work Index. This Index represents the ore hardness.
