The answer is calculated by multiplying the volume of the ball by the density of the material weight volume density for example calculate the weight of a two inch diameter lead ball volume 4 r 3 3 a universal constant 31416 4 12566 r radius
Mar 10 2011 re how can i calculate new ball size and weight desing for ball mill hi we have a similar mill pregrinding with hammer crusher and monochamber mill thisis what a proposed based on literture review i did and others agree its more and less correct but remember it all depends on your mill feed size after pregrinding
The model requires three inputs in its original form and a "density corrected" variation includes a fourth input mill effective inside diameter to calculate factor a mill fraction filling of the charge to calculate factor b mill fraction of critical speed to calculate factor c for density correction effective density of the mill charge output
Jan 01 2016 ball mill diameter 457 m inside liner diameter 439 m ball mill load 35 ball charge mass 113 t ball size 64 mm step 5 the diameter efficiency factor f 3 in step 2 can now be determined using equation figure 810 as the id of the mill has been provisionally established as 439 m then f 3 0914 as d 381 m
Pulp density can be measured using a marcy density of nuclear density gauge the solids concentration can be estimated using a common expression or directly measured pulp density density rho is the ratio of the mass weight m of a substance and the total volume v water has a density of 10gmml or 10gmcm 3 1000kgm 3 1tonnem
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
Note that the critical speed of the mill is calculated as follows critical speed in rpm 423sqrt d d with d the diameter of the mill in meters and d the diameter of the largest grinding
The distribution of residence time has been determined as a function of feed rate for both liquid and solids and as a function of initial size ball diameter holdup weight mill length feed
Jan 01 2012 graphical abstract the slurry density and ball load volume inside a laboratory ball mill have been estimated by two statistical multivariate methods i partial least squares pls and ii combination of pls and radial basis functions neural networks rbfpls based on characteristic features contained in the ball and slurry sensor data
Calculate the solids split in the cyclone and the water split 2 a mill processes 10000 tonnes of ore per day with an average moisture content of 4 h2o a total of 2000 tonnes per day of water are added to the head end of the primary grinding stage several ballmills
ball top size bond formula calculation of the top size grinding media balls or cylpebsmodification 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
Structure ball mill is a cylindrical or conical shell rotating about a horizontal axis partially filled with a grinding medium such as natural flint pebbles ceramic pellets or metallic balls grinding media high density alumina 9095 alumina or steel media is widely used in grinding operations
Ball mill is suitable for grinding various ores and other materials it is widely used in mineral processing building materials and chemical industry it can be divided into dry and wet grinding methods according to the different ways of discharging it can be divided into two types grid type and overflow type
Jun 26 2017 step one calculate your effective cutting diameter a ball nose end mills effective cutting diameter d eff differs from its actual cutting diameter when utilizing an axial depth of cut adoc that is less than the full radius of the ball calculating the effective cutting diameter can be done using the chart below that represents some common tool diameters and adoc combinations or by
Mar 02 2014 31 industrial ball mill the ball mill utilized in the sampling survey has an inside diameter of 73 m and length of 96 m and is run in open circuit under normal operating conditions the mill ball loading is 30 of total mill volume mill rotational speed is 75 of critical speed slurry solids concentration is 75 solids feed rate is 330 tph
Take g 10 ms 2 22 7 water 1000 kgm 3 and the air density inside the ball as air 13 kgm 3 do not consider the material the ball is made it is already included in the value of air density
The ball mill is the most common ore grinding technology today and probably more than 50 of the total world energy consumption for ore grinding is consumed in ball mills
