PROBLEM TO BE SOLVED: To provide an impact type crusher reducing the production ratio of coarse particles and capable of extending the durable life of a hammer head. SOLUTION: The impact type crusher has a reversibly rotatable rotor 5 variable in the number of rotations horizontally provided in a casing 1, a large number of hammer arms 6 of which the base end parts are attached with hinges to the outer periphery of the rotor and a rectangular plate-shaped hammer head 10 mounted on the leading end part of each of the hammer arms 6 to extend in the radial direction of the rotor. The rotor can be rotated at a high or low speed in either forward or reverse rotation. The hammer head is formed of an almost rectangular plate-shaped hammer head main body 15 made of steel and triangular plate-shaped chips 16 and 17 made of a sintered hard alloy. A triangular cut-off place 13 covering a main abrasion region due to high speed rotation is provided to the hammer head main body on the front side in the high speed rotary direction of the rotor is provided to the hammer head main body and a triangular cut-off place 14 covering a main abrasion region due to low speed rotation is provided on the front side in the low speed rotary direction of the rotor. The chips 16 and 17 are attached to both cut-off places of the hammer head main body. COPYRIGHT: (C)2004,JPO
