Consider, for example, a single gyratory crusher of any type, arranged to operate in closed circuit with a vibrating screen, and set so that 70 percent of the original feed will be crushed to a size that will pass through the screen openings. Also, for the sake of simplicity, let us assume that the screen will take out all of this 70 percent ...
Crushers • Squeeze or press the material until it breaks • Mostly used to break large pieces of solid materials into small lumps • Use of crushers in agricultural operations is limited . Types – Jaw crushers – Gyratory crushers . Jaw crusher • Feed is admitted between two jaws, which are open at the top like V
Jaw crushers can be divided into two basic types, single and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation, along with the toggle plate, causes a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...
