This paper presents the breakage properties of five different porous materials based on a kinetic model, which was commonly used in the cement industry. For this purpose, firstly, standard Bond's grindability tests were made for five porous samples. Secondly, eight different mono-size fractions were ground between 1.7 mm and 0.106 mm formed by a V2 sieve series.

Abstract The present study deals with an analysis of the selection function for mills using balls as grinding media. The grinding mechanism assumes that a particle caught by two colliding balls will be ground only if the ball impact generates or activates at least one single crack within the particle causing the fragmentation. The derived selection function becomes …
