ABSTRACT:
A jaw crusher for bulky waste and like matter, comprising two groups of jaws or shanks movable towards and away from each other, the jaws or shanks within each group being spaced at an interval corresponding to the width of the jaws or shanks of the opposite group. The jaws or shanks of one group are adapted, as they move towards the other group, to travel at least partly into the interspaces between the jaws or shanks of the opposite group, and include driving units actuating at least one group of jaws or shanks in order to move them towards the opposite group. At least one of the jaws included in at least one group of jaws is movable relative to the remaining jaws of the same group, the jaws are individually movable by individually actuable driving units, and the driving units are provided with sensors for sensing exerted power and actuating a programmable central unit which controls the relative position of the jaws so that it will vary during the cutting-up operation.
