PROBLEM TO BE SOLVED: To solve a problem that, although crushing treatment is an essential process in industrial wastes in our country, the lifetime of a crusher is remarkably inhibited by the damage of blades and the shear loading working on a driving shaft due to contamination of uncertain heterogeneous articles. SOLUTION: An obtuse cone key 7 is incorporated into a contact point between the driving shaft 1 of the crusher and a cutter-fixing device (a cutter-lock flange) so as to withstand huge impact loading acting on the driving shaft 1. The taper angle of the cone key 7 resists the huge impact loading and facilitates the detaching of a cutter 2.
