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.Filling Degree Of Ball Mill Ppt - FSHolland,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. Get PriceThe operating principle of the ball mill,Therefore, the work of the mill with partial load conditions is unprofitable. Energy consumption for ball mills is a function of many factors: the physical properties of the ground material — its specific gravity and hardness; the degree of drum filling by grinding balls; the number of drum rotations, etc. Ball mills have low efficiency,

to ball filling variation in the mill. The results obtained from this work show, the ball filling percentage variation is between 1.2– 3.7% which is lower than mill ball filling percentage, according to the designed conditions (15%). In addition, acquired load samplings result for mill ball filling was 1.3%.Ball Mill - SlideShare,Nov 18, 2008· 4.2 The speed of the shell: The maximum speed avoiding centrifugal force , Where 4.3 Mass of balls The bulk volume of the balls is {30-45%} of the volume of the shell of the ball mill and the feed is filling the empty space between the balls where the static porosity is about 40% ,and the balls charge is vary from 30-45% 5.Ball mill- what is the % of filling by balls and % of,,Ball mill- what is the % of filling by balls and % of filling by materials ? ball mill size dia=2 meter, length 8 m, inner dia= 1.888 m , material to be grinded= illuminate, ball size= 20,30,40 mm,
