Study on Liner wear in Single Toggle Jaw Crushers: A …

2017-7-9 · A jaw crusher consists of a fixed jaw and a swing jaw. The swing jaw, which is inclined at an acute angle to the vertically fixed jaw, swings with the help of a pitman mechanism that is mounted on an eccentricshaft. The inertia force for crushing the material is provided by two heavy flywheels mounted at both sides of the eccentric shaft.
