Under the action of external force, the metal stress reaches strength, and the metal immediately breaks. There are several ways to apply force to a shredder machine.
1. Crush: Place the metal between the sides. After the force is applied, the compressive strength of the metal reaches the compressive strength and is crushed.
2. Fracture: Place the metal between the plane and the teeth of the shredder machine. When a clamping force is applied, tensile stress is generated in the metal. When the tensile stress reaches the tensile stress, it splits in the direction of the effect force.
3. Fracture: Place the metal between two toothed surfaces. When a pinch force is applied, the bending stress reaches the bending strength of the material, and the metal breaks.
4. Impact crushing: Metal ruptures under the impact of high-speed rotation. This method can be done in various ways. Due to the effect of the applied force in a short time, the deformation cannot extend to various parts of the impacted object, and only large stress occurs at the impacted part, and the internal microcracks break. Therefore, the damaging effect of dynamic load is much larger than that of static load.
5. Grinding: Place metal between two relatively moving work surfaces to apply pressure and shear. When the shear stress in the metal reaches its shear strength limit, the metal breaks.
In fact, various shredder machines are the result of several shredding methods during metal crushing. At the same time, however, one or two methods of forcing will be the main method, as well as other methods of destruction. Due to the different physical and mechanical properties of various metals, the force application method of the shredder machine should be coordinated with the mechanical properties of the metal to achieve a good crushing effect. For fragile gold Genus, it is more advantageous to choose splits, bends, and shatters than to choose impact or co-shatter. For harder metals, if grinding is used, fine grinding is added. For high-resistance, high-adhesion metals, grinding and splitting methods are more appropriate.
