Ball Mill Operating Principles Components Uses

Ball Mill Operating Principles Components Uses

several types of ball mills exist. they differ to an extent in their operating principle. they also differ in their maximum capacity of the milling vessel, ranging from 0.010 liters for planetary ball mills, mixer mills, or vibration ball mills to several 100 liters for horizontal rolling ball mills.jul 01, 2011 the experimental setup is shown in fig. 3.the length of the tube equals 0.5 .12 and its inside diameter is 0.044 is filled with water of assumed viscosity sm. six balls with different ball-tube diameter ratio which is defined as the ball diameter divided by the inside diameter of the horizontal tube, are used.the free vibration response of the system is measured.
