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 ...
