PROBLEM TO BE SOLVED: To provide an apparatus capable of efficiently crushing a foamed resin material. SOLUTION: A plurality of fixed blades are fixed in parallel at gaps from one another inside a housing 20. A rotation blade apparatus 50 is rotated on its own rotation axial line inside of the housing 20. In this case the crusher comprises transverse blades 70 which are installed almost in parallel to the rotation axial line and pass the peripheral parts of the tip ends of the fixed blades following the rotation of the rotation blade apparatus 50 and radial blades 62a, 62b which are extended approximately radially from the rotation axial line following the rotation of the rotation blade apparatus 50 and pass the gaps between neighboring fixed blades 30. |
