calculate the filing degree in a cement ball mill

The measurement of the ball charge volume load (or filling degree) is essential to maintain the absorbed power of the mill and consequently the mill production. The most common way to evaluate the filling degree is the measurement of the free height inside the mill (vertical distance between the top of the charge and the lining in the mill axis).

Ball Mill Loading - Dry Milling - Paul O. Abbe

The starting point for ball mill media and solids charging generally starts as follows: Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) Add to this another 10%-15% above the ball charge for total of 23% to 25% product loading.

2006-3-1  The total load of balls was calculated by the formal fractional mill volume filled by balls (J), using a bed porosity of 0.4. The fractional filling of voids between the balls (U) can be calculated by U = fc / 0.4J; fc is the formal fractional mill volume filled by powder using a powder porosity of 0.4 . The ball load distribution composed of grinding balls of 30, 20 and 10 mm was varied (Eq.
