Abstract
Grinding media influence the energy consumption and efficiency of the grinding process during the calculation of the Bond Work index (BWi), a well-known method for selecting comminution equipment, evaluating milling efficiency, and calculating required milling power. Traditional grinding tests often choose steel balls as the grinding media, but ceramic balls are used widely currently with their high efficiency in grinding. This study aims to calculate the Bond Work index with steel and ceramic balls and explore the equation for the BWi of mixed grinding media (steel and ceramic balls). This paper also proposes a conversion equation of BWi between the mixed grinding media (steel and ceramic balls) and conventional media (steel balls). The results combined the advantages of ceramic and steel balls to improve the grinding capacity and reduce energy consumption.
期刊介绍:
The aim of this international peer-reviewed journal of the Society for Mining, Metallurgy & Exploration (SME) is to provide a broad-based forum for the exchange of real-world and theoretical knowledge from academia, government and industry that is pertinent to mining, mineral/metallurgical processing, exploration and other fields served by the Society.
The journal publishes high-quality original research publications, in-depth special review articles, reviews of state-of-the-art and innovative technologies and industry methodologies, communications of work of topical and emerging interest, and other works that enhance understanding on both the fundamental and practical levels.
