CRUSHER

摘要

The invention relates to a crusher for crushing solid material the crusher comprising a frame; at least one crusher rotor arranged rotatably to the frame and having crusher blades secured to the circumference thereof a yielding counterblade structure arranged for cooperation with the crusher blades of the rotor for concurrently crushing and cutting said material and for yielding when encountering non-crushable material and when overloaded and a yielding and downwardly openable set of screens below the crusher rotor, whereby the counterblade structure is linked to the frame of the set of screens and made turnable towards it with respect for the pivoting shaft in a yield situation; and the set of screens is linked to the crusher frame on the opposite side of the crusher rotor with respect to the counterblade structure and its pivoting shaft and made downwardly collapsible about the pivoting shaft of the set of screens.

主权项

1. A crusher for crushing solid material, the crusher comprising
a frame (1); at least one crusher rotor (2) arranged rotatably to the frame (1) in-eluding crusher blades (3) secured to the circumference thereof and crushing the material; a yielding counterblade structure (4) arrange for co-operation with the crusher blades (3) of the crusher rotor (2) to concurrently crush and cut said material, the counterblade structure (4) being arranged to yield when en-countering non-crushable material (12) and when overloaded; and a yielding downwardly openable set of screens (5) that is arranged below the crusher rotor (2) at a selected axial distance from the crusher blades (3) of the crusher rotor (2);characterized in that
the counterblade structure (4) is linked to the frame (7) of the set of screens (5) and made turnable towards it in a yield situation with respect to the pivoting shaft (6); and that the set of screens (5) is linked to the crusher frame (1) on the opposite side of the crusher rotor (2) with respect to the counterblade structure (4) and its pivoting shaft (6) and to be downwardly collapsible about the pivoting shaft (8) of the set of screens (5).
