Roll Crushers. It is generally considered that Roll Crushers are specially adapted for intermediate crushing, taking a product from rock- breakers with a maximum diameter of from ¾ inch to 1½ inches, and reducing it to a size passing through a screen of 12 or 16 meshes to the square inch. Finer crushing, however, is often carried out.
