How Jaw Crushers Work. A jaw crusher uses compressive force for breaking ore pieces. Compressive force is applied by two jaws (dies), one of the crusher jaws is stationary (fixed jaw) whilst the other is moving (swing jaw). Material is fed into the top feed opening (gape) and gradually moves downwards towards the lower discharge outlet.

Jaw-crusher Construction. Jaw crushers are heavy-duty machines and hence must be robustly constructed. The main frame is often made from cast iron or steel, connected with tie-bolts. It is commonly made in sections so that it can be transported underground for installation. Modern jaw crushers may have a main frame of welded mild steel plate.

Jaw crushers are classified by the method of pivoting the swing jaw (see attached figure). In the Blake crusher the jaw is pivoted at the top and thus has a fixed receiving area and a variable discharge opening. In the Dodge crusher the jaw is pivoted at the bottom, giving it a variable feed area but fixed delivery area.
