However, Single Roll Crushers provide limited product sizing and are limited in throughput capacity. Double Roll Crushers feature two rotating roll shafts that crush material between the teeth and roll bodies. These types of Roll Crushers produce a cubical product with minimal fines generation, and can handle higher capacities.
