ABSTRACT:
This invention relates to improvements and modifications to a rock crusher. The rock crusher has at least two jaws the jaws being driven at different ends to each other. The non-driven end of at least one jaw is sufficiently free to allow vertical movement of that jaw with respect to the other jaw. This vertical movement imparts a grinding action in addition to the crushing action of the rock crusher. This removes the problems which can occur with wadding and can produce a very fine ground rock.
