Abstract
A ball or tube mill which includes at least one grinding compartment, support means for supporting the grinding compartment, drive means for eccentrically driving the grinding compartment and a plurality of inflatable bellows supporting the support means for oscillating movement. In a preferred form of the invention, the support means is supported on four spaced inflatable bellows inclined with respect to one another such that their central axes intersect at a cone apex above the center of the mill. Means may also be provided for adjusting the pressure within each of the bellows to thereby adjust the height of the bellows individually.
