Now many manufacturers in the recovery of recycling of waste materials are used to double the shredder, because not only tear tear plastic material double wide range and high production efficiency, by the majority of users. The main working parts of the double shaft shredder are a pair of relatively rotating rollers, and the rollers are equipped with spiral arranged teeth. After the material enters the machine, the teeth of the high hardness wear resistant material made by staggered rotation are cracked and sheared, and then split, broken and crushed to be smaller than the set size, and then the machine is forced to exclude the machine.
The roller of double shaft shredder is driven by a motor through a reducer. It has a large torque and meets the hard debris. It will automatically reverse under the action of the PLC automatic control system, and it will be repeatedly reversed until the material is broken and discharged. The principle of equipment in different industries have different names: metal shredder, coal grading crusher, garbage crusher, construction waste crusher, the word "shredder" in english. According to its own structural characteristics can be called spiral tooth roller shredder, commonly used in biaxial form, as well as single axis, four axis and other forms.
Functional features of double shaft shredder:
1. material is mainly affected by tensile stress and shear stress are broken, rather than the traditional crusher main pressure stress. The material from the weakest link is destroyed, so the energy consumption can be greatly reduced, the research report can be reduced to the same 1/10;
2. the pull action of the broken gear roller rotates at opposite directions, the crushing ratio is greatly improved, the maximum can reach about 300, and the traditional equipment is about 3-5;
3. two rollers have the function of cleaning each other, so they can be forced to discharge. Any material which is easy to be winded on the moving parts of the ordinary crusher can be discharged automatically;
4. scope of application: This machine is suitable for living and industrial materials recycling, coal mineral processing, gravel production, cement and metallurgical raw materials preparation and other industries.
