am working in a plant with single stage grinding using a ball mill we operate the mill power at around the feed size is we use mm steel balls. the ball mill is in closed circuit with classification cyclones. there are cyclones and we operate with a pressure of about pa.
ball mills give a controlled final grind and produce flotation feed of a uniform size. ball mills tumble iron or steel balls with the ore. the balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. the feed to ball mills is
jun 01, 2018 fig. shows the variation of size class with the milling time for the two feed size distributions. for this coarser feed the 2010 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.
