Abstract. The grinding process in ball mills is notoriously known to be highly inefficient: only 1 to 2% of the inputted electrical energy serves for creating new surfaces. There is therefore obvious room for improvement, even considering that the dominant impact mechanism in tumbling mills is a fundamental liability limiting the efficiency.
