Sep 01, 2013 This equation allows the calculation of the product size distribution from a mill once d ij is determined. The calculation of d ij includes the aforementioned S and B functions, which can be determined in a laboratory batch mill. However, these parameters are sensitive to milling conditions such as the mill rotational speed, ball filling.Figure 5. High–low wave ball mill liner Materials The selection of the material of construction is a function of the application, abrasivity of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.

Enter the width of a mill shell liner. Note this is not the width of a lifter! You may use the Mill Liner Effective Width calculation to determine this value. The mill critical speed will be calculated based on the diameter (above) less twice this shell liner width. Mill Actual RPM Enter the measured mill rotation in revolutions per minute.The balls which could be of different diameter occupy 30 – 50 of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
Ball Size as Initial Charge. Commercial ball sizes 10 – 150 mm Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., d †“V = 0.40.Oct 19, 2017 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) F — the feedstock grain size in 80 of the material, μm.
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.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 the grind for a primary grinding duty. Figure 5 shows the evolution of the mill discharge product size in relation to the lifting effect of the liners.
