Working principle of Ball Mill ball cement milling Mar 03 2015 Ball mill is an efficient tool for grinding many materials into fine powder The Ball Mill is used to grind many kinds of mine and other materials or to select the mine It is widely used in working operation of a ball mill argentina bvmbouwnl
The working principle of the ball mill includes the following steps: in the continuous operation of the ball mill the material is fed into the drum through the central hole (one of the covers) and moves with the exposure of the grinding medium Material grinding occurs when the particles between the grinding ball and the grinding ball are impacted and the ground material is discharged
The critical speed of ball mill is given by where R = radius of ball mill r = radius of ball For R = 1000 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 speed
