FLS Double Roll Crushers are capable of impres-sively high throughput rates up to 14,000 tph thanks to the customised tooth and liner design and optimised 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.New insights into double roll crushing ScienceDirect
