Jan 01 1989 introduction the energy consumption for grinding according to bond 1961 is deter mined by the formula 10 10 i the work index is determined by grinding experiments carried out in a labo ratory bond ball mill based on the results of grinding experiments numerical values of the work index wi are calculated according to the formula 03017516890350 1989 elsevier science
In grinding selecting calculate the correct or optimum ball size that allows for the best and optimumideal 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 andor mill liner wear and
Mar 10 2015 this paper proposes the use of the energy required to produce new 75 m material hereafter referred to as size specific energy or sse after powell et al 20032010 as a simplified measure across a broader range of particle sizeshukki 1979 first introduced this method to characterise the efficiency of closed grinding circuits later levin 1992 argued that the energy
55 000 mtph mill line with 2 600 hp gearless sag mill and two 11 625 hp ball mills specifications manuals and design calculations for the mineral processing end mill
Specific energy consumption is the power draw of a mill the bond ball mill work index determination is a common example to calculate the operating work index of a circuit you must
Dec 12 2016 ball mill power calculation example a wet grinding ball mill in closed circuit is to be fed 100 tph of a material with a work index of 15 and a size
Bondbarratt specific energy consumption sabc model this is a sag or ag mill plus ball mill model that estimates the overall circuit specific energy consumption using the classical bond work index equation for multistage crushing and singlestage ball milling e ssbm including rowland efficiency factors the circuit e total is equal to the e ssbm plus an inefficiency factor cf related to the
Mar 08 2013 calculation of ball mill grinding efficiency dear experts please tell me how to calculate the grinding efficiency of a closed ckt open ckt ball mill in literatures it is written that the grinding efficiency of ball mill is very less less than 10 please expalin in a n excel sheet to calcualte the same thanks sidhant reply
