Double Roll & Teethed Roll Crusher
Double Roll Crusher. Mechanically, the teethed roll crusher is a very simple machine. The two rolls are carried in bearings, supported on two very heavy and rigid bed castings which are secured on the concrete foundation by a number of large anchor bolts. The bearings, in addition to being bolted to these bed castings, are prevented from
