: Hammer wear too large; sieve fracture. Remedy: Replace the hammer; replace sieve. Elastic coupling produces percussion. Cause: The pin loosening; elastic ring wear; Remedy:

stop pin and tighten the nut; replace elastic ring. Reduced yields. Reason: sieve gap is

Blockage; feeding uneven. Remedy: parking, cleaning sieve gap obstruction; adjust feeding mechanism. Percussion sound generated inside the machine. Reason: non-broken material

into the inside of the machine; liner loose Circular vibrating screen fasteners, hammer hit the liner; hammer or other parts breakage. Exclude
