The jaw crusher works by using a moving jaw and a fixed jaw to crush and grind the rocks. The material is fed into the jaw crusher by a vibrating feeder, and then it is crushed between the two jaws. The jaw crusher is made up of several parts, including a fixed jaw, a moving jaw, and a toggle plate. The fixed jaw is mounted to the frame of the ...

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 ...

A jaw crusher is a machine that breaks down big rocks into smaller ones. It has two jaws, one fixed and the other moving, that work together to crush the material. The fixed jaw is mounted on a frame and cannot move, while the moving jaw is connected to an eccentric shaft. Jaw crushers are used extensively in the mining, quarrying, and ...
