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

There are two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft…

The processing system of the double-toothed roller crusher makes it possible to crush any type of raw material from hard (limestone and rock) to soft (clay, soil and mud) or even elastic-like wood or rubber tyres. The rotation speed, especially if compared to traditional crushers, is very low; so low, in fact, that tip speed is under 3 m/s.
