The scale-up of grate-discharge continuous ball mills
The grate-discharge of the mill comprised 151 holes of 0.635 cm diameter spaced uniformly in a 12.7-cm diameter plate. All the con- tinuous grinding experiments were carried out at 60% of mill critical speed using 2.54-cm (1-inch) balls at 25% filling and a 14 X 20 mesh sample of dolomite as the feed. The kinetic parameters for the breakage …

Optimising Ball Mill Liners to Maximise Tonnage
In testing four mill liner profiles for 13′ x 12′ overflow ball mills. Climax found that an improved design increased mill tonnage by 3 tons per hour while reducing finish grind by 1.7% + 100 mesh, reduced liner wear rate, and almost doubled liner life. During a 5-year test series, four liner contours were tested in Climax's 13′ x 12 ...
