Ball mill energy consumption can be improved by changing its rotational speed when grinding efficiency decreases or by modifying the mill liner shape in a way that ball trajectory can be maintained within an optimum range for the longest period of time possible. This dissertation is an original intellectual product of the author, O. Mejia Alarcon.

The document analyzes data from ball classification calculations for different ball mill lengths. It shows the number of pieces and total weight of balls categorized by diameter and how these values change as the ball mill length increases from 0.5 to 7.5 meters. As length increases, the percentage of larger diameter balls (70 and 60mm) decreases while the percentage of smaller …

Ball Mill Design A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1. For fine regrinding in open circuit, …

8.1.1 Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types - rod, ball, pebble autogenous and semi-autogenous. The grinding action is induced by relative motion between the particles of media - the rods, balls or pebbles. This motion can be characterized as collision …
