Jaw Crushers

Jaw Crushers are used extensively throughout the world by the aggregate, mining and recycle industries. Their large physical size and rectangular feed opening enable them to receive a larger feed size than most other types of crushers. Rugged construction, simplicity of design and the ability to crush most types of material, including hard abrasive stone, make them ideally suited for use as the primary crusher within a crushing circuit.

This style of crusher uses compression to crush rock by squeezing it between two jaws: one stationary and one movable. The movable jaw (Pitman) is attached to an eccentric shaft that causes it to move in a reciprocating motion. Rock enters the crushing chamber from the top and moves through the chamber, which gets narrower as it gets deeper, until it is caught between the two jaws, where it is squeezed until it fractures.

Typical applications:

Stone Crushing
Concrete Crushing
Asphalt Crushing
Ore Crushing

ELRUS Jaw Features

Welded Steel Frame
construction 2-2.” steel plate welded con struction which has been stress relieved to ensure a long trouble free life.

Cast Steel Pitman
1 3/4"-2.” cast steel construction which has been machined to give a closely toleranced fit with other components. The pitman also features a replaceable plate to help protect the barrel from damage due to oversize or slab type material.

Bolt-on Pitman Lip
All ELRUS jaw crushers feature Bolt-On Manganese Support Lips. The bolt-on lips gives the owner/operator the option to bolt-on the lip rather than having to weld it in place. Therefore they are easy to maintain and replace during liner changes.

Spherical Roller Bearings
All jaw crushers come with off the shelf spherical roller bearings for both the pitman and the frame. The pitman bearings are oil lubricated and the frame bearings are grease lubricated from a central location to eliminate the need to shut down for lubrication.

Flywheels
One piece cast flywheels in 48” or 60” diameter sizes. Hydraulic Jaw Adjust with Shims Jaw crusher settings can be easily changed with our standard hydraulic pump used to take the pressure off. This allows you to add or remove shims as needed for the correct setting.

Optional: Hydraulic toggle with tramp iron relief system Replaces the toggle plate. Pressure relieves to allow passage of material that is not crushable

Replaceable Parts

ELRUS has designed our jaw crushers to include replaceable parts that make maintenance simpler. These parts include a bolt on toggle slide with wear plates, and replaceable lower toggle seats for both the stationary and the movable jaw manganese.
