Customer ServiceOct 20, 2016 · Some indication as to media consumption can be obtained from power consumed in grinding. For example, balls or rods will generally wear at a rate of about 1# for each 6 or 7 kilowatt hours consumed per ton of ore. Liner consumption is generally about one-fifth of the media consumption. GRINDING RODS Steel Grinding Rods
Get Price ListAs for the influence of hardness, generally speaking, as the hardness increases, as long as it does not break, the single consumption of the grinding media ball decreases, and the deformation of the ball body is reduced, the absorption deformation energy of the ball body is small in the process of crushing, and the energy can be used more for crushing mineral grains The productivity of the mill can be increased
Get Price ListAug 26, 2017 · Large surface area (thousands of square meters) of grinding media and mill liner. ... For example, in a sulfide concentrator, addition of lime to the pyrrhotite regrind mill reduced ball consumption by 40%. The lime was added at 0.6 kg/t of ore which changed the …
Get Price ListThe volume of grinding media in a mill is directly related to grinding efficiency. The higher the volume of grinding media the more effective the grind. Balls must be added to maintain the media load and mill power draw. The power draw increases as balls are added and decreases as media …
Get Price ListAug 01, 2013 · Consumption of grinding media in mills is an economically important problem. Current understanding of factors influencing wear loss of steel balls in mills is reviewed. Modelling of grinding media wear is considered and alternative approaches discussed
Get Price ListBall Mill Media (kg/kWh) = 0.0944*Ai^0.299. Aidan Giblet and J. Seidel published a paper on the 2011 SAG conference (MEASURING, PREDICTING AND MANAGING GRINDING MEDIA WEAR) and they obtained. Ball Mill Media (kg/kWh) = 0.0817x(Ai)0.498. the two equations are very similar
Get Price ListSep 17, 2018 · Based on the model originally developed by Benavente, a projection of grinding media consumption typically results in an error of approximately ± 12%, which until recently, was considered a satisfactory result given the lack of alternate methods to better predict consumption. Grinding Media consumption is a significant expenditure item for any mineral processing operation, therefore the …
Get Price ListJul 30, 2012 · Ball mills are a similar shape to that of the rod mills except that they are shorter with length to diameter ratios of 1 to 1.5. As the name implies, the grinding media in these mills are steel balls. The particles size of the feed usually does not exceed 2.5 cm
