Oct 19, 2017 There is a mathematical solution to this problem the Bond formula. It uses to help determine the grinding media optimal size must be loaded into the ball mill for proper operation ensure. The calculation formula is below B the grinding balls diameter, mm A the correction factor (for grinding balls A 20,17 for cilpence A 18,15)
micrometers in size. According to the Bond standard procedure, the work index is determined by simulating a dry grinding in a closed circuit in the Bond ball mill to achieve 250% circulating load (Bond, 1949, 1952, 1961). The test is performed on a raw material approximately weighing 10 kg, which coarseness is 100% -3.327 mm.
The geometry of a mill with conical ends is shown in Figure 8.6. The total volume inside the mill is given by Vm 4 D2 mL 1 2(Lc L) L 1 (Dt/Dm) 3 1 Dt/Dm (8.16) The density of the charge must account for all of the material in the mill including the media which may be steel balls in a ball mill, or large lumps of ore in an
Ball Mill Charge Sensor Logan Sainlez. Mill Steel Charge Volume Calculation We can calculate the steel charge volume of a ball or rod mill and express it as the of the volume within the liners that is filled with grinding media while the mill is stopped the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge

Aug 30, 2019 1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and
- Ball top size (bond formula) calculation of the top size grinding media (balls or cylpebs)-Modification of the Ball Charge This calculator analyses the granulometry of the material inside the mill and proposes a modification of the ball charge in order to improve the mill efficiency
The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the
Dec 10, 2016 Differences up to 6,2% in the Bond ball mil work index can be observed due to different siz distribution in P 80 calculation.. 13 ores were tested using the Bond ball mill grindability test, obtaining P 80 using different interpolation functions. Rosin Rammlers model showed the best behavior, so its use must be not only suggested, but recommended.
