Abstract

In the study, the effect of different grinding media on breakage parameters was investigated. Ceramic and steel balls were used as the grinding media. It was observed that the grinding of ignimbrite obeyed first-order breakage kinetics law in the case of ceramic and steel balls. Breakage rates were higher for steel ones comparing to ceramic balls. Furthermore, it was found that the primary breakage distribution function depends on the feed size (i.e., non-normalized), and depends on the different grinding media. The effect of grinding time on the product particle size distribution has also been investigated.
