feeder. Fines in the jaw crusher increase the percentage of contact area against the jaw dies. This increases scratching and grinding and reduces life time. 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.

Jaw crusher units with extra-long, articulated crusher jaws prevent coarse material from blocking while moving all mounting elements of the crusher jaw from the wear area. A more even material flow may be affected if the transfer from the prescreen or the feeder trough is designed so material simply tilts into the crushing jaw.
