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 convex in relation to ...
A mixture of CaO and silica-gel (SiO2) was subjected to grinding using a planetary ball mill, followed by heating to investigate the temperature for synthesizing para-wollastonite (CaO·SiO2). The MC treatment of the mixture brings about amorphous aggregates with almost homogeneous chemical composition. 2-hours MC treatment enables us to ...
