Secondary crushers, including cone crushers and hammer mills, further reduce material size before passing it on to tertiary units for the final sizing. The difference, for instance, between a cone crusher's mantle and a gyratory crusher's gyrating head, dictates the nature of the crush and ultimately the output. ...
