As a result, operating costs in a cement plant will be reduced. Ball mills used in the cement industry are inefficient grinding technologies. Any small improvement in the operation of ball mills can lead to significant annual energy savings (Tiggesbӓumker and Müller, 1983, Viswanathan and Reddy, 1992, Schnatz and Knobloch, 2000). Thus, new ...

Both power and ball cost per ton of —200 mesh produced decreases with a decrease of mill speed. A slow speed, high pulplevel mill with sufficient additional volume to equal the capacity of an equivalent higher speed mill will make up the difference in capital cost between the two mills in well under a year's operating time through the ...

Grinding Balls. Steel balls ranging from ¾ to 5 in. in diameter are used. Rods range from 1½ to 4 in. in diameter and should be 3 to 4 in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4 or 5in. balls are more commonly used for ballmill grinding.

Larger process plants have a lower operating cost per unit weight of material than a smaller plant using similar processes, but they also have a larger initial capital cost. For reference, a 1 Mt/a mill will have a capital cost within 25,000 /t/h and 50,000 /t/h. A 20Mt/a mill will have a capital cost within 10,000 /t/h and 20,000 /t/h ...

In mills operating at low cascading speeds, abrasive wear is considered to be the dominant wear mechanism (Hukki, 1954). In highly abrasive ores, approximately 12 kg of grinding media can be consumed per ton of ore milled (Moema et al., 2009). In wet milling, this assumes proper pulp coverage of the ball surfaces, not too thick to ...
