Basic principle Ball mill is generally used to grind material 14 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system. There is a specific operating speed for most efficient grinding. At a certain point, controlled by the mill speed, the load
Planetary Ball Mill Working Principle. Planetary Ball Mills consist of several cylindrical grinding jars positioned on the sun wheel as shown on the figure which are filled with loose grinding balls. Two superimposed rotational movements move the grinding jars Like in a planetary system the grinding jar rotates on a orbit around the centre.
Working Principle amp Operation. The apparent difference in capacities between grinding mills listed as being the same size is due to the fact that there is no uniform method of designating the size of a mill, for example a 5 x 5 Ball Mill has a working diameter of 5 inside the liners and has 20 per cent more capacity than all other ball mills designated as 5 x 5 where the
