Collision between each other, the material continues to produce cracks, until loose and crushed. When the particle size of the material is smaller than the discharge gap between the impact plate and the blow hammer, it will be discharged from the crushing chamber. However, when the existing impact crusher crushes materials, a large amount of materials that are smaller than the discharge gap between the impact plate and the blow hammer are usually mixed with the materials, and these materials will occupy a part of the crushing cavity after entering the crushing cavity. until the blow hammer hits these materials to the left end of the accommodating cavity, these materials can fall out from the discharge port under the action of gravity, these smaller materials will not only occupy the volume of the accommodating cavity but also greatly Affect the crushing speed of other materials.
