Cataracting Regime | Scientific.Net

The aim of this paper was to study the transitional phenomena between cascading, cataracting and centrifuging motion. In order to observe these transitions, experiments were carried out in a tumbling mill of 300 mm diameter, and three sizes of chrome steel balls were used as grinding media. Each size of ball was employed in three different ...

The mill speed is one of the vital parameters in ball mills, which is normally specified as a fraction of critical speed. It determines whether the load behavior is predo-minantly the cascading regime, the cataracting regime or the centrifuging regime. In general, the industrial ball mills rotational speed operates at 70%~80% of critical

Ball Mill - an overview | ScienceDirect Topics

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

For Peer Review

Cataracting balls hit the mill shell, causing ball-to-wall collision. Finally, the surging impact is when balls collide in midair, which results in ball-to-ball collision (Mishra and Rajamani, 1992). Surging of the charge may take place at all speeds and it is particularly damaging at high speeds (Behera et al., 2007).
