how to improve grinding efficiency of a mill

Addition of pebbles to a ball-mill to improve grinding efficiency .Ball-mills are used widely for secondary grinding. Loveday (2010) reported on laboratory tests in which small pebbles (7–25 mm) were used in various proportions with balls. The optimum proportion of pebbles, by volume, was found to be about 25%. Substantial savings in power and ball consumption were achieved, with.how to improve grinding efficiency of a mill,Maximize your grinding efficiency Steel grinding rods and balls - To ensure that your equipment plus wear and spare parts are of high quality and are designed to keep your mill rolling. • To see to it that installations are being carried out correctly and quickly, while making sure that safety is never compromised. • To find a partner who can help you improve your total grinding efficiency,.
