Slag crushing

When a jaw crusher is equipped with the ASC system, the crushing forces are carried by massive hydraulic cylinders mounted into the rear header casting. If an uncrushable object enters the crusher cavity and crushing forces reach the preset maximum level, oil starts to escape out of the cylinders and the setting releases.
