Jaw crushers are heavy duty machines. They are robustly manufactured. Jaw Crusher consists of a main frame and two plates which move like jaws. Both jaws are adjusted to an intense angle to each other. First jaw is pivoted in such a manner that it moves relatively towards another fixed jaw. The movable jaw plate pivoted at the top on the swing-jaw shaft. In the jaw type of crusher oscillation of pivoted jaw is caused to motion by the action of toggles and pitman, that moves upside and down actuated by the eccentric through the medium of pulleys mounted on the drive shaft |
