The roll surfaces of the Double-Roll Crusher are smooth. The materials to be crushed are fed from the top. As the rolls rotate they are nipped between them and get crushed by compression, and are discharged from the bottom. Compression crushing is extremely efficient, as energy is only used to crush those particles larger than the gap between the rolls. Fines are minimised because already ...

Dynamics in double roll crushers - ScienceDirect

The forming of the cake even at low reduction ratios explains why the cumulative PSD curve of a DRC is more similar to the one of a piston-die press than to the one of a jaw crusher even in single particle comminution. An agglomerated material bed may resist much higher forces as a single particle of comparable size and of the same material. As a result, the forces acting in a double roll ...
