Exploring the Link between HY Wet Ball Mill Work Index and Grinding Energy Consumption

Abstract

In evaluating ore grinding energy consumption using the Bond ball mill work index, discrepancies were identified. As a result, an investigation into the determination method of Hou Ying (HY) wet ball milling work index (W_HY) for Gongchangling magnetite ore was conducted to determine the correlation between W_HY and grinding energy consumption at varying particle sizes. The research results indicated that W_HY had an error less than 3.33%, which is closely aligned with on-site grinding energy consumption. This surpassed the numerical error of 15.9% in the Bond ball grinding power index and demonstrated superior accuracy in representing ore grinding energy consumption, particularly in wet scenarios. Given its precise reflection of real-world conditions, W_HY is a valuable tool for optimizing ball-milling processes by enabling more than 3% enhancements and making it a valuable tool for industry applications compared to traditional approaches.
