Effect Of Ball And Feed Particle Size Distribution On The

Effect Of Ball And Feed Particle Size Distribution On The

Jun 01, for this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. the availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. the 10 mm ball size is unable to nip the large particle size hence the breakage rate is.Jun 01, this approach has the added advantage in that different particle sizes can be effectively milled in a ball mill because each media size can effectively break a particular particle size during the size reduction process ensuring that the product fineness is.
