Physical synthesis methods include sedimentation processes, rotor speed mills, high energy ball mills and mixer mills. - in general, phosphorus (p) nanoparticles are prepared by purifying rock phosphate and grinding them with a high energy ball mill or mixer mill smaller than 500 nm and altered properties.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.

Ball Mill Operating Speed

Ball Mill Operating Speed

The critical speed of ball mill is given by, where r = radius of ball mill; r = radius of ball. for r = mm and r = 50 mm, n c = 30.7 rpm. but the mill is operated at a speed of 15 rpm. therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical.The critical speed of the ball mill is the speed at which the centrifugal force is equal to the gravity on the inner surface of the mill so that no ball falls from its position onto the mill shell. ball mill machines usually operates at 65-75% of critical.
