ABSTRACT:
A rock crusher comprises a pair of rotors spaced apart to define a throat therebetween and driven in opposite directions. Impactor bars on the rotors crush rock that is delivered to the rotors and passes the broken rock fragments through the throat. The rock crusher may be conveniently provided in a harvesting vehicle such as a potato harvester to crush rock that has been picked up with and separated from the crop. The rocks can be crushed to a sufficiently small size that they may be conveniently returned to the field surface, and thus the arrangement avoids the trouble and expense that would otherwise be entailed in collecting and disposing of the separated rock.
