Thus, much of the coal introduced into the crusher C is not acted upon by the rotor R in the sense that the breaker rings 42 engage that coal and rake it along the screens 42. Instead, the coal passes through the holes 60 in the breaker plate 54. As a result, the crusher C has greater capacity than conventional crushers of the comparable size.
