Get PriceThe influence of mill speed and pulp density on the grinding - saimm. between the balls in the mill, is known and we are then able influence of mill speed and pulp density on the grinding efficiency for secondary stage grinding.
Get Pricethe milling efficiency is the quality of grinding media. The use of inferior grinding media does not only compromise the milling efficiency, but also comes with a cost penalty due to the premature breakage of balls in service. Steel grinding media fail if there is a significant variation in chemical composition, hardness and microstructure of

Get Price01.04.2017· 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 no loss in grinding capacity.
4Get PriceMills usually operate in the range 65 - 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge).
Get Pricecharge motion. It is well known that ball milling efficiency varies during the lifetime of the shell liner. For instance, the mill performance could become worse or better by putting in a new shell liner. Data from pilot plant test work illustrates the influence of the shell lifting effect on
Get PriceAlso the grinding efficiency of ball mill will reduce. If the steel balls are too small, even the collision probability is relatively high, but the energy of single steel ball is very small, which cannot efficiently grind the ore particles, also leading to the reduction of grinding efficiency.
