What is the working principle of the double shaft shredder?
Double-shaft shredder, also known as double-shaft shredder, shearing design principle, alloy knife material, through shearing, tearing and extrusion to reduce the size of the material. Strong impact resistance, broken metal knives do not break.
The double shaft shredder is mainly used in: domestic waste, industrial waste and leather scraps, organic waste, medical waste, RDF, hazardous waste, bulky waste, paper mill twisted rope, etc.
The working principle of the double-shaft shredder: During the crushing process, the claws on the rotor pull the material into the crushing cavity. The blades are arranged in a staggered and occlusal manner, so that the material can be cut and broken in both the horizontal and vertical directions at the same time. After the material is broken, it is intercepted and peeled off by the partition, and finally discharged downward.
The main working part of the crusher is a pair of relatively rotating rollers, and the rollers are equipped with gear teeth arranged in a spiral. After the material enters the machine, it is bitten and sheared by the gear teeth made of staggered high-hardness wear-resistant materials, and is split, broken and pulverized to a size lower than the set size, and then forced to be excluded from the machine. The roller is driven by the motor through the reducer and has a large torque. When encountering difficult-to-break objects, it will automatically reverse under the action of the PLC automatic control system, and rotate forward and reverse many times until the materials are broken and discharged. This principle equipment has different names in various industries: metal shredder, coal grading crusher, domestic waste shredder, construction waste shredder. According to its own structural characteristics, it can be called a spiral toothed roller crusher (shredder), which is commonly used in the form of double shaft (double toothed roller), as well as single shaft and four shafts (four toothed roller).
Features
1. The material is mainly crushed by tensile and shear stress, rather than the compressive stress of the traditional crusher. The material is destroyed from the weakest link, so the energy consumption can be greatly reduced, and the research report can be reduced to 1/10 of the same;
2. The pulling action of the crushing toothed rollers rotating in opposite directions greatly increases the crushing ratio, which can reach up to about 300, while the traditional equipment is about 3-5;
3. The two rollers have the function of cleaning each other, so they can be forced to discharge materials. Any materials that are sticky or wet, or materials that are easily wound on the moving parts of ordinary crushers, such as wire and steel strips, can be automatically discharged.
