The diameter of ball used will vary between 12 mm and 125 mm W o r k i n g The ball mill is used for the grinding of a wide range of materials and it copes with feed up to about 50 mm in size. The material to be ground may be fed in through a 60 degree cone at one end and the product leaves through a 30 degree cone at the other end.
Planetary ball mills are well known and used for particle size reduction on laboratory and pilot scales for decades while during the last few years the application of planetary ball mills has .
Nov 13 2013 There are considerable problems in making an ideal comparison between the results of ball milling. These problems mainly from the experimental difficulties in being able to utilise the techniques of ball milling size regimes. The reduction of size of particles in
Next the speed of ball milling also influences the size reduction process. The faster the speed of ball mill the faster and more efficient is the particles size reduction process. However a velocity which is too high and too low may cause the particles to stay at the bottom of the mill and thus decrease the efficiency of size reduction process.
The specific rates of breakage of particles in a tumbling ball mill are described by the equation Si axαiQz where Qz is the probability function which ranges from 1 to 0 as particle size .
