WJG Series Jaw Crusher

WJG Series jaw crushers are the right choice for primary crushing plants installations at quarries, mines, gravel pits and even recycling industries.There are also an ideal choice for the replacement of existing double and single toggle jaw crushers.

In order to get optimum capacity and maximum lifetime of wear parts, consider the following points:

1. Check the feed size

• Oversize feed material decreases capacity and can cause unnecessary stresses to the crusher components.

• Small feed size increases wear at the bottom of the cavity and may cause poor utilization of wear parts.

2. Check the feed arrangement

• In order to reach optimum capacity and maximize on the life of the wear parts, the crusher cavity should be full.

• The feed must be distributed evenly across the crushing chamber.

3. Apply proper scalping

• Fines (material smaller then CSS) should be removed from the feed material. This is done by the grizzly bar section of the feeder. Fines in the jaw crusher increase the percentage of contact area against the jaw dies. This increases scratching and grinding and reduces lifetime.

4. Choose the correct jaw dies for the application

5. Check the wear profile of the jaws

• An uneven wear profile will decrease capacity, increase wear, and increase crushing forces.
