DISCHARGE PART STRUCTURE AT SINGLE-SHAFT CRUSHER

摘要

PROBLEM TO BE SOLVED: To constitute a discharge part structure for releasing a biting of foreign matters when the foreign matters are bitten to a rotation blade of a single-shaft crusher to a compact size. SOLUTION: In the single-shaft crusher provided with a rotation rotor 5 having a rotation blade 5a and a fixed blade 6, a sidewall near a discharge part is formed by an upper sidewall 10 for fixing a screen and a lower sidewall 11 for a discharge and an ascending/descending sidewall 10a of the upper sidewall 10 is upwardly liftably formed. An inspection window is attachably/ detachably attached on the lower sidewall and a hydraulic cylinder 14 is equipped as a lifting means to be capable of lifting the ascending/descending sidewall 10. The sidewall is disposed at a position projecting by the minimum limit by a distance required for providing the lifting means to constitute the discharge part structure to a compact size.
