In coarse comminution, double roll crushers (DRC) are used for the size reduction of blasted materials and in secondary comminution. In the primary crushing stage, DRC with toothed rolls are of particular importance. In contrast to smooth rolls, these offer improved nip conditions so that larger particles can be nipped, and crushed.
In addition, for safe and reliable operation of the smooth double-roll crusher, the influence of nip conditions, rotation speed and feed material characteristics on the crushing and bearing force dynamics were investigated [32]. To overcome the disadvantage of low reduction ratios of conventional roll crushers (typically limited to …
