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.

The overarching principle guiding jaw crushers is a compression action. A V-shaped alignment houses the fixed jaw, serving as the immovable surface that facilitates the initial breakage. Simultaneously, the movable jaw, in a swinging motion, exerts force on the incoming material, compelling it against the unyielding surface of the fixed jaw.

Jaw crushers are used as primary crushers, or the first step in the process of reducing rock. They crush primarily by using compression. The rock is dropped between two rigid pieces of metal, one of which then moves inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece.

Reversible jaw plates extend service life and the stationary jaw lifts easily from the frame for cleaning the inner parts. Sealed heavy bronze bearings are protected from dust and dirt, and lubricated by grease cups. Jaw size is 4x9in (102x229mm) with a 4x2.375in (102x60mm) opening. Reduction adjusts for 1/16–5/8in (1.6–15.9mm) particle size.
