Ying 8 studied the influence of the mills rotation rate the ball filling ratio The grinding balls bulk weight in fully unloaded mill Apr 11 2017 Thus during calculating the grinding balls mass in ball mill after measuring the mill filling degree with grinding media needs to use the grinding balls bulk weight whose diameter was determined earlier
Calculating ball mill filling calculation of filling volume in ball mill Calculate Ball Mill Grinding Capacity A) Total Apparent Volumetric Charge Filling including balls and excess slurry on top of the ball charge plus the interstitial voids in between the balls expressed as a percentage of the net internal mill volume (inside liners)
The degree of filling the mill with balls also influences productivity of the mill and milling efficiency With excessive filling the rising balls collide with falling ones Generally filling the mill by balls must not exceed 30–35 of its volume Productivity of ball mills depends on drum diameter and the relation of drum diameter and length
Ball Mill Filling Degree At constant ball filling degree this mill's performance increases as the pool angle and dry ball angle go toward zero To recap the dry head angle is the difference between the ball head and pulp head angles and the pool angle is the difference between the ball foot and pulp foot angles
