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 HoggFuerstenau 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 ...

Energy consumption represents a significant operating expense in the mining and minerals industry. Grinding accounts for more than half of the mining sector's total energy usage, where the semiautogenous grinding (SAG) circuits are one of the main components. The implementation of control and automation strategies that can achieve production objectives along with energy efficiency is a ...

Quantifying and improving the power efficiency of SAG milling circuits. Comminution circuits based on SAG (semiautogenous grinding) mills are not necessarily power efficient. So called critical sized particles can build up in the SAG mill charge, limiting mill throughput, and increasing unit power consumption.
