Dr. R. Peter King covers the field of quantitative modeling of mineral processing equipment and the use of these models to simulate the actual behavior of ore dressing and coal washing as they are configured to work in industrial practice. The material is presented in a pedagogical style that is particularly suitable for readers who wish to learn the wide variety of modeling methods that have ...
Matrix models were used to represent the grinding units: rod mill and pebble mills. Parameters for these models were computed using a method developed by Mular. Classifier parameters were computed by the Powell search method for the Plitt model. System Assumptions and Model Development The grinding circuit for which this mathematical simulation ...

Jan 30, 2019· 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.
1. Introduction. Semi-autogenous grinding (SAG) mills are presently one of the most widely used alternatives in the field of mineral size reduction as a result of their comparative advantages, such as higher processing capacity, lower physical space requirements, and lower investment and maintenance costs, as compared to conventional circuits.
