(1) Crushing method: Pressing the two crushing working faces to pressurize the material to break the material. The characteristic of this method is that the force is gradually increased, and the range of force is large. (2) Crushing method: The material is broken by the force of the sharp teeth wedged into the material, which is characterized by the concentrated action range of the force and local rupture. (3) Fracture method: When the material is broken, the material is broken and broken due to the bending force concentrated in the opposite direction. This method is characterized by the fact that it is subjected to bending force in addition to the force at the point of action of the external force. Therefore, it is easy to break the ore. (4) Grinding and stripping method: The crushing working surface moves relative to the material, thereby generating shearing force on the material. This force acts on the surface of the ore and is suitable for the grinding of fine materials. (5) Impact method: The crushing force is instantaneously applied to the material, so it is also called power breaking. Currently use mechanical crusher for crushing effect ore, while often the combined effects of several disruption methods.
