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.

W niniejszych badaniach sprawdzono wpływ różnych mediumów mielących na parametry pękania. Jako mediumy mielące użyto kule ceramiczne i stalowe. Zaobserwowano, że w przypadku kul ceramicznych i stalowych mielenie ignimbrytu było zgodne z kinetycznym prawem pękania pierwszego rzędu. Wskaźniki pękania w przypadku kul stalowych były wyższe w porównaniu do kul ceramicznych. Ponadto odkryto, że podstawowa funkcja rozkładu pęknięć zależy od rozmiaru zasilenia (tzn. nieznormalizowanego) i od różnego medium rozdrabniającego. Sprawdzono również wpływ czasu rozdrabniania na rozkład rozmiaru cząsteczek.
