ABSTRACT:
A tumbling mill such as a tube or ball mill, wherein an outer shell is provided with an interior liner made up of a series of rings surrounding and distributed along the axis of the shell and each defining and surrounding an interior hollow milling space which has the cross section of a star with rounded points, in a plane normal to the shell axis, with this space having sharp corners extending inwardly toward the shell axis and alternating with the rounded points. The series of rings which form the liner in the shell are angularly offset one with respect to the next in a haphazard, non-uniform manner, and the configuration of the star-shaped space which is surrounded by each ring is that of a pair of superposed squares which have rounded corners and which are angularly offset one with respect to the other so that the rounded corners of one square alternate with the rounded corners of the other square to provide the space which is surrounded by each ring with the configuration of an eight-pointed star having rounded points.
