Although there are many types of crushing machines, according to the different methods of applying force, there are methods such as extrusion, bending, impact, shearing and grinding on the material crushing. In the crushing machine, the force application is very complicated, and sometimes several kinds of force are present at the same time. Of course, there is only one or two main forces in a certain crushing machine. Since the shape of the material particles is irregular and the physical properties of the materials are different, the pulverization method used is also different. The mechanical force is used to pulverize the materials according to different application forces: 1 crushing puts the material between two working faces. After applying pressure, the material is broken due to compressive stress reaching its compressive strength. This method is generally used to crush large pieces of material. 2 Crushing Place the material between a flat surface and a sharp working plane. When the sharp working plane presses the material, the material will be crushed in the direction of the pressure line of action. The reason for the splitting is that the tensile stress on the split plane meets or exceeds the tensile strength limit of the material. The tensile strength limit of the material is much smaller than the compressive strength limit. 3 The broken material is broken by bending stress. A two-point simply supported beam or a multi-supported beam that is subjected to concentrated load by the crushed material. When the bending stress of the material reaches the bending strength of the material, it is broken and broken. 4 Impact crushing material is broken by impact force. Because its crushing force is instantaneous, its crushing efficiency is high, the crushing ratio is large, energy consumption is small, and the impact crushing has the following conditions: (1) Impact of moving objects on materials (2) High-speed moving materials impact on fixed working surface (3) High-speed moving materials impact each other (4) High-speed moving work body impacts on suspended materials 5 grinding (grinding) After a certain pressure and shear force are applied between the material and the moving working surface, when the shear stress reaches the shear strength limit of the material, the material is pulverized, or the shearing and grinding action when the materials are rubbed against each other And the material is broken. The main type of crushing machinery 1 According to the different construction and working principle, the commonly used crushing machinery has the following types: (1) The jaw crusher relies on the movable jaw for periodic reciprocating motion to crush the material entering the two jaws. (2) Hammer Crusher The material is subjected to the impact of the hammer head at high speed and the material itself is impacted at a high speed on the fixed lining to break the material. (3) Cone crusher (gymatic crusher) The eccentric rotation of the inner cone causes the material between the two cones to be crushed and crushed and broken. (4) The material of the impact crusher is struck by the high-speed moving plate hammer, causing the material to collide with the counter-attack plate at high speed, and the materials collide with each other and break. (5) The material of the roller crusher falls between two rollers that are parallel to each other and rotate oppositely (opposite rotation). Under the friction of the surface of the roller, the material is pulled between the rollers and crushed by the roller. . Rubber Accelerator Masterbatch
