Q: Why does the Four Roller Crusher eliminate the need for a vibrating screen?
Because the machine features two levels of crushing chambers. The top pair handles the initial breakdown, and the bottom pair performs precision fine grinding. The discharge gap is physically set to your required size, ensuring the output is uniform without needing a secondary screen.
Q: Can this machine process wet or sticky coal gangue during rainy seasons?
Yes. APEX Four Roller Crushers utilize a screen-less design and low-speed extrusion. This prevents the “pasting” effect found in hammer crushers. It comfortably handles materials with up to 30% moisture content without clogging.
Q: How does the equipment protect itself from unbreakable objects like iron tramp?
The equipment is fitted with a spring or hydraulic automatic retreat device. When an unbreakable object enters, the rollers instantly retract to let it pass safely and then return to their original position, protecting the motor and rollers from damage.
