Introduction of double shaft shredder
Shredders are widely used, and many irregular and even soft materials can be shredded by shredders. The most widely used industry is the shredding of various plastic products, and other applications include recycling of waste tires. , crushing of rubber products, wood, waste household appliances, papermaking raw materials, wire and cable, PVC, nylon, fibers, and composite materials, thin metal products, etc., and even shredders can be used to shred scraped cars as a whole, its damage The effect is amazing.
Working principle and structure of double shaft shredder:
1. Working principle
The main working parts of the double-shaft shredder are two relatively rotating knife rollers installed in parallel on two horizontal hexagonal shafts. When the material enters the crushing cavity and is caught by the claws on the blade on the knife roller, the material is sheared and squeezed, and finally enters the discharge hopper through the gap between the two knife rollers. It can be adjusted by adjusting the size and width of the claws. The size of the discharge can be changed.
2. Equipment structure
The double-shaft shredder is usually divided into equipment table, feed hopper, shredding box, reducer motor and other power devices, transmission mechanism and other parts:
(1) Workbench. It mainly includes supporting frame for the main engine, guardrail, working platform, etc., which are used to facilitate the operation of the staff and the observation of equipment, etc.;
(2) Shred the box. The shredding box is the core working part of the equipment. Two oppositely rotating hexagonal shafts are installed inside the box. The cutter shaft is installed with a polygonal blade. The blade and the blade are separated by a bushing. The inner hole of the cutter is six The edge shape fits with the knife shaft to ensure that the shredding operation will not slip. The width of the blade determines the shredding size of the material. A fixed knife structure is installed on the shredding box, which works together with the moving knife to shred the material;
(3) Power structure. The double-shaft shredder uses a high-torque motor to provide power, and transmits the power to the reducer through the belt, and the reducer increases the torque through deceleration, which greatly improves the shredding size of the equipment;
(4) Power transmission mechanism. The power transmission structure of the equipment includes belts, pulleys, reducer sprockets, knife shaft bearing boxes and other structures.
In addition, it should be noted that if the shredder is overloaded, it will cause the motor to burn out, making the machine unable to work normally, and it will also cause trouble for the user. Beijing shredder can test the current situation, the ambient temperature is not suitable If it is too high, a reasonable selection of the motor of the metal shredder can save costs for the user, and what are the requirements for the configuration to bring considerable economic benefits. Only by the guidance of the manufacturer's technicians, especially those with many years of experience, can the user use it normally.
