摘要： PROBLEM TO BE SOLVED: To prevent the damage of rotary blades and a fixed blade due to overload when a load equal to or greater than a prescribed value acts on the fixed blade in shearing crushing by moving the fixed blade away in the direction of separation from the rotary blades by using a separation mechanism and to improve the shearing crushing efficiency of materials to be crushed. SOLUTION: A crushing chamber 2 is formed in a crusher body 1, a feeding port 3 is formed in the upper part of the crushing chamber, a rotary shaft 4 is installed horizontally in the crushing chamber, a rotor 5 is arranged on the rotary shaft, a plurality of rotary blades 8 are arranged in the outer circumferential portion of the rotor, and a fixed blade 9 which collaborates with the rotary blades to shear and crush the materials to be crushed is arranged in the crusher body. Furthermore, a separation mechanism 12 is arranged which moves the fixed blade away in the direction of separation from the rotary blades when a load equal to or greater than a prescribed value is applied to the fixed blade.

摘要： PROBLEM TO BE SOLVED: To improve the crushing efficiency of a material to be crushed by eliminating a cavity in the upper part of a crushing mechanism to realize the smooth drop of the material to be crushed and preventing the idle run phenomenon of the crushing mechanism from occurring. SOLUTION: A crushing chamber part 2 is formed in a crusher body 1, a loading aperture part 3 through which the material to be crushed W is loaded, is formed above a crushing chamber part 2 and the crushing mechanism 4 capable of crushing the material to be crushed W is internally installed at the crushing chamber part 2. In addition, a thrust feeding member 10 capable of thrust-feeding the material to be crushed W toward the crushing mechanism 4 is arranged on the side of crushing chamber part 2, a reciprocating mechanism 11 capable of reciprocating the thrust feeding member 10 is arranged, and an engagement part 13 capable of clearing the residence state of the material to be crushed W by engaging the part 13 with the material W, is mounted on the thrust feeding member 10.
