16/02/2009 Batch wet grinding of zeolite was studied with emphasis on a kinetic study in a laboratory size steel ball mill of 200 mm diameter The breakage parameters were determined by using the single sized feed fractions of − 850 + 600 µm, − 600 + 425 µm and − 425 + 300 µm for the zeolite samplesThe S i (specific rate of breakage) and B i,j (primary breakage distribution) values were

02/08/2013 In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do Often, the ball used in ball mills is oversize “just in case” Well, this safety factor can cost you much in recovery and/or mill liner wear and tear

28/04/2017 This is true on a bucking board, in tubemills, ballmills, and grinding pans Given the possibility of returning a fullfeed load to any mill, it has been my experience that the effective work in the grinder is almost proportional to the quality of the return feed (2) Again speaking generally, the shorter the tubemill the greater is the quantity of return feed necessary to keep it loaded
