INTRODUCTION Vertical stirred milling is a wellrecognized technology for the secondary, regrind and fine grinding applications and are increasingly replacing coarser ball mill applications in secondary and tertiary field. The driving force behind this trend is the higher energy efficiency obtainable for the vertical stirred mill.

1. Fine grinding in the mining industry. It has been estimated that approximately 2% of the world's energy usage is applied to mineral comminution, and around a quarter of this is used specifically in metalliferous ore grinding [1] where it is typically the most energy intensive set of operations [2].The purpose of comminution in ore processing is to reduce particle size in ...
