The crushing ratio of a jaw crusher results from the maximum achievable final fineness in relation to the maximum feed size. For Retsch jaw crushers, this lies between 26 and 220. A high value reflects the capacity of a jaw crusher to accept large sample pieces and provide powerful crushing performance, resulting in high final fineness.

Feed opening (depth of the cavity) defines the maximum feed size of the crusher. In the C jaw crusher, the feed opening is measured from the top of the tooth of the fixed jaw to the bottom of the tooth of the movable jaw in a straight line perpendicular to the center line of the crushing cavity. The maximum feed size is approximately 8 0% of ...
