PROBLEM TO BE SOLVED: To provide a twin shaft type crushing machine capable of preventing the wear and deformation at the bottom of a casing and greatly improving crushing performance. SOLUTION: This crushing machine has a box-shaped casing 1 which is provided with many slits 2 in parallel at its bottom 1a, two pieces of shafts 4 which are disposed in parallel with each other perpendicularly to slits and are rotated to directions different from each other on the bottom of this casing, rotary blades 7 which have a semicircular shape having U-shaped plural edges 7a, 7b, 7c opened in the rotating direction of these shafts, are mounted at both shafts, having spacings at their peripheral edges from each other of both shafts and are made insertable into the respective slits and stationary blades 10 which are positioned between both shafts, are mounted at the bottom and shear waste cooperatively with the respective rotary blades. The stationary blades 10 are so formed as to have an inverted U shape across the bottom between the adjacent slits and to bring both flanks into sliding contact with the flanks of the adjacent rotary blades 7. |
