Jaw crushers are one of the two classes of primary crushers and consist of a heavy main frame carrying a stationary fixed jaw and a pivoted, swing jaw. The swing jaw can be pivoted at the top (Blake crusher) or at the bottom (Dodge crusher), and is given an oscillating motion by means of toggles and a pitman riding on an eccentric shaft.Web
