Special Issue Information

Dear Colleagues,

Comminution is the biggest energy-consuming operation in mineral processing. The aim is to liberate locked minerals in order to provide the best conditions for further separation units. If liberation is not enough, the separation processes will be inefficient.

Experimental studies on mineral comminution are essential to understand how a mineral breaks and what the particle size distribution of the products will be after this breakage process. In this regard, experimental studies and numerical development take a leading role in defining comminution processes. With this information, industrial comminution may be optimized using particle size distribution sensors and advanced control systems with artificial intelligence. If we wish to apply all of these technologies, we must know the breakage process linked with the parameter process, and experimental and numerical studies allow us to collect these data.

This Special Issue aims to collect new work in this field and to disseminate knowledge around the world so as to advance this area of mineral processing.

Ceramic ball milling has demonstrated remarkable energy-saving efficiency in industrial applications. However, there is a pressing need to enhance the grinding efficiency for coarse particles. This paper introduces a novel method of combining media primarily using ceramic balls supplemented with an appropriate proportion of steel balls. Three grinding media approaches, including the utilization of steel balls, ceramic balls, and a hybrid combination, were investigated. Through an analysis of the grinding kinetics and the R–R particle size characteristic formulas, the study compares the breakage rate and particle size distribution changes for the three setups. The results indicate that employing binary media effectively improves the grinding efficiency for +0.3 mm coarse particles while maintaining the energy-saving advantages of ceramic ball milling. Simultaneously, the uniformity of the ground product is ensured. This proposed approach has been successfully validated in industrial applications, providing robust theoretical support for the expansion of ceramic ball milling applications. Full article
