Claims

[Claims for Utility Model Registration] (1) Two horizontal crushing shafts are provided in a box-shaped frame, and a plurality of crushing blades are arranged on both of the crushing shafts so that each crushing blade is inserted between the crushing blades of the other crushing shaft. In a coarse crushing device that is provided in multiple rows, one crushing shaft rotates at a higher speed than the other, and the material gripped by the crushing blades of both crushing shafts is crushed by the difference in rotational speed.
A coarse crushing device characterized in that the back surface of the crushing blade on the low-speed rotating side extends over a wide range and is swollen into an approximately arcuate shape so that it can engage with the cutting edge on the high-speed rotating side. (2) Two horizontal crushing shafts are installed in the box-shaped frame, and a plurality of crushing blades are installed on both of these shafts in multiple rows so that each crushing blade is inserted between the crushing blades of the other crushing shaft, and one In a coarse crushing device in which a crushing shaft rotates at a higher speed than the other crushing shaft, and the material gripped by the crushing blades during both crushing operations is crushed by the difference in rotational speed,
A coarse crushing device characterized in that the cutting edge of the crushing blade on the high speed rotating side is provided at two or more locations in the radial direction from the axis.
