In actual operation these new rolls run almost as smoothly as a lathe. The 24-in. rolls are run at 100 rev. per min.; the 18-in. at 150, and the 12-in. at 250. This system of crushing has been developed gradually. There are eight of these rolls now in actual operation, all exhibiting the same uniform control over the wear of the roll-shells.
Integration with Existing Equipment: The crusher's integration with the feeders, screens, and the conveyors, within the plant layout considered, is also another factor which need to be considered to ensure a smooth operation.
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.
