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：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
