PROBLEM TO BE SOLVED: To efficiently crush even waste having large void rate by making the edge angle of rotary blades an acute angle, using the rotary blades having >=2 kinds of the diameter and specifying adjacent 2 rotary blades in a horizontal crusher useful for crushing the waste by the cooperation of the rotary blades and a fixed blade. SOLUTION: In crushing a material to be crushed by a crushing part having a driving part, a hopper 2 and a roller and composed of the rotary blades 5 attached to a rotary shaft 4 and the fixed blade 6 provided under the roller, >=2 kinds of the rotary blades 5 having different diameter from each other are used and attached at a position adjacent to and in contact with each other. And the rotary blades 5 are formed so as to satisfy a relational expressions of (DL-DS)/2=(0.3 to 3)HL=(0.3 to 3)HS=(0.3 to 5)tL=(0.3 to 5)tS when the diameter of the large sized rotary blade in 2 adjacent rotary blades is represented by DL, the thickness thereof is represented by tL, the height of the tooth of the tooth form thereof is represented by HL, the diameter of the small sized rotary blade is represented by DS, the thickness is represented by tS and the height of the tooth is represented by HS. |
