Motion of Balls through the Porous Bed. The transport of slurry through the ball-bed in tumbling mills depends on the distribution of voids inside the charge and the speed of the mill. When balls of different sizes are present in the mill, then there is a tendency for the balls …
The type of mill also can affect the selection of grinding media. Ball Mills use very large media while Attritors employ media ranging in size from 1/8" to 1". Horizontal mills require much smaller media, as small as 0.05 mm to 2 mm. To read detailed specs and submit a quote, click here for our metallic media or here for our non-metallic media.

SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

Stadler number = 6.64(log d + 8.07) + 1 where d is in centimeters. Thus the top ball size is 114 mm. Divide the % largest size ball in the optimum charge (column (4)) by the percent of this charge found in the equilibrium charge, which is obtained by the constant feed of the largest ball, given in Table 7.3. In this case, 15/23 = 0.652.

A database of slurry residence time collected from industrial ball mills was established and used to investigate the typical range of the volume-based slurry residence time in a normal industrial ball mill operation, and to set up an onset point for ball mill overfilling warning in the specific energy-based ball mill model (Shi and Xie, 2016).
Dec 01, 2013· The particle size reduction results from the complicated dynamic interaction of the balls with turbulent slurry during the ball mill process, imposing a difficulty in quantitative interpretation of the observed phenomena of: (1) the existence of the optimized ball size at a given rotation speed; and (2) the decreased optimum ball size with increased rotation speed (rpm).
