Crusher and liner of the crusher

摘要

PROBLEM TO BE SOLVED: To provide a crusher which can adjust the size of a crushed object that can pass through a movable lattice member and prevent flat large waste from passing through a gap between a lattice member tip and a liner surface.SOLUTION: A crusher 1 includes: a crushing chamber 6 provided with a rotor 2 having an impact member 3 at an outer periphery part; a discharge chamber 5 which is formed adjacent to the crushing chamber 6 and discharges a crushed object crushed by the impact member 3; a movable lattice chamber 11 which is provided at the discharge chamber 5, has a through hole 12 which allows the crushed object having a size smaller than or equal to a predetermined size to pass therethrough, and can pivot around a horizontal pivot shaft 14; and a liner 10 which is provided at an area facing a tip of the movable lattice member 11 on an inner surface of a wall forming the discharge chamber 5. Multiple projections 18 for blocking the crushed object from passing through a gap between a surface of the liner 10 and the tip of the movable lattice member 11 are formed on the surface of the liner 10.SELECTED DRAWING: Figure 1
