equation uses mill dimensions (inside the liners) the density of the mill charge and an empirical "power number" that encapsulates the mill speed and volumetric filling 0 %(1 234 (2) Where: • D is the mill diameter inside the liners m • L is the mill effective grinding length m • P is the power evolved at the mill

Mill power models have been used in a variety of ways in industrial practice since power directly equates to throughput and fineness of ground product We first start with Hogg-Fuerstenau Power Model and show how this model successfully predicted the power draw of many grinding mills in several mining operations Then we show how this model was on the verge of being able to predict the
