  • Determining Particle Size Distribution From A Ball Mill

    A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis. 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.Rate at each screen size is calculated from a torque mill test as in the example that follows. Torque mill solids load during test 11.25 kg (24.8 lb) of ball mill feed sample from plant survey. Sample is reconstituted with water to be the same percent solids as the plant ball mill discharge. Mill speed 35.2 rpm (65 percent of critical speed).

    In this paper, the milling parameters of high energy ball mill (Fritsch Pulverisette 7) like vial geometry, number and size of balls and speed of the mill were modelled and discussed. Simulations through discrete element method (DEM) provide correlation between the milling parameters. A mathematical model is used to improve and develop this process.The changing particle size distribution of the milled good as a function of time is most easy to characterize qualitatively if the material has initially only one particle size. At the start of milling the first size class is continually diminished, (Curve A Fig. 3) first faster and then slower. An average particle size class is initially.
