Claims

[Scope of Claim for Utility Model Registration] (1) A large number of disc-shaped blades are fixed at a predetermined pitch along the axial direction to a pair of substantially horizontal and parallel rotating shafts, which are provided in a casing having an input port at the top. While rotating the pair of rotary cutters in a symmetrical direction with the blade of one rotary cutter inserted between the adjacent blades of the other rotary cutter, the material to be crushed is passed through the input port between the pair of rotary cutters. In the crusher, the pair of rotary cutters are installed such that the lower surface of one rotary cutter is located diagonally below the lower surface of the other rotary cutter, and the casing has a An enclosing wall made of an inclined wall and an arcuate wall is formed to surround at least the upper part of the pair of rotary cutters with a predetermined space in between when viewed from the axial end direction of the cutters, and this enclosing wall includes at least one of the above-mentioned A crusher characterized by having an opening/closing lid provided below a rotating cutter. (2) The crusher according to claim 1, wherein all or part of the portion of the opening/closing lid that faces the one rotary cutter is constructed of a mesh or a perforated plate.
