<p>A crusher (100) comprises a stand; a cylinder-shaped crushing chamber (1) having a cylinder wall and arranged above the stand transversally; a feed hole and a discharge hole arranged under the crushing chamber; and a rotary blade device (2) supported to rotate freely in the crushing chamber. At least a part of the upper wall portion of the cylinder wall (15) forms a guiding wall portion (13), and the guiding wall portion is configured to a shape which is gradually away from the rotation trace of the end of the rotary blade device in the radial direction along the rotation direction of the rotary blade device so as to throw the materials along the guiding wall portion. A blocking wall (14) is formed between the end of the guiding wall portion and the cylinder wall in the downstream side of the rotation direction of the rotary blade device, and the blocking wall is configured that the materials can knock against the blocking wall after the materials are thrown along the guiding wall. The crusher changes the motion trace of the materials to improve the crushing effect and can remove the dust doping in the materials to improve the service life by improving the structure of the crushing chamber.</p> |
