ABSTRACT:
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 the balls are better agitated within the heap of balls effecting coarse grinding.
