Predicting charge motion, power draw, segregation and wear in ball mills using discrete element methods ... This corresponds to a periodic remixing and resegregating of the flow and demonstrates that the internal motions of the ball mill charge are not steady with time but possess intriguing structure. The average underlying segregation level ...

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell Cmodel or Nordberg equation to get the RPM that corresponds to 75% for that mill diameter.

An internal lining for cylindrical ball mills has riffles approximately extending in circumferential direction and webs located between the riffles and further has elevations and/or depressions arranged transversely to the circumferential direction. This allows fine grinding between the balls and the riffles. The balls are lifted to a higher level by the elevations and/or the depressions and ...
