Capacity Calculations of the Crasher with Stops on a Roll

The capture of a crushed piece occurs due to the stop located on the roll (see Fig. 1 ); in this case, the condition for formation of a complex stress state in the crushed piece is observed, and the energy consumption is reduced by 39–40% [ 9 ]. Fig. 1. Schematics of the crusher with stops on a roll. Full size image.
