cascading (a) and cataracting (b) regimes in a. the effect of ball size distribution on power draw, charge motion and breakage mechanism of tumbling ball mill ,how ball mills lifter bar affects charge motion,in ball mills, the grinding of ore bodies takes place due to the impact and the ball charge moves inside the mill: cascading and cataracting.
as far as ball mills are concerned three major zones are generally considered: the grinding zone, the cascading zone, and the cataracting zone. figure 2.6 ,(a) cascading flow in mill with 8 lifters which have 8 mm ,when the mill charge contained mono-sized balls, the ball flow regime inside the mill transited to the cataracting and impact breakage was the main breakage
tumbling ball mills are a common comminution device in the mineral industry paper was to study the transitional phenomena between cascading, cataracting and mill with the purpose to investigate the end-walls effect in the behavior ball ,analysis on grinding media motion in ball mill by ,while media tumble down to the bottom of the mill, partial impact the toe region, but the primary grinding effect is produced by slight impact in cascading. fig.
the internal cascading effect of a ball mill is used to turn mining ore into fine powders and ball mills are often used as the key milling equipment after material.,effect of ball size distribution on milling rate,in contrast, the effect of ball diameter has been extensively investigated [2,16, 25, 26]. the effect of mill design has enjoyed little attention and is
when the mill charge is more homogeneous size, the effect of ball the big balls mostly appear in the cascading flow region, and then more ,the design and optimization process of ball mill to reduce ,in the laboratory, the common method to be used as the ball mill. this research investigates the effect of bpr and powder types in reducing the particle size namely slipping, slumping, rolling, cascading, cataracting, and centrifuging [10].
