<p>Crushing apparatus in which a pivotally mounted first crushing member (24) is provided with a plurality of crushing regions (31, 32, 33, 34, 35) located at various distances from the pivot axis (25), which is offset, so that as the first crushing member is cyclically advanced towards and retracted from a second crushing member (14), successive crushing regions approach the second member closer than the preceding crushing region, to crush material (37) by a combination of compression and shear forces, and a transverse member (52) is provided in the crushing apparatus downstream of the throat (50), to divide the outflow of crushed fragments and hold up oversized material.</p> |
