The crushing principle of the double-shaft shredder is that the two cutter shafts are equipped with staggered blades, and the two cutter shafts are shredded by the shearing of the blades and the tearing of the teeth during the rotation of the two shafts. The main shearing mode is the shearing action of the adjacent moving knife edge, and the secondary shearing mode is the tearing action of the moving knife teeth. In terms of equipment structure, the double-shaft shredder is mainly composed of the following parts: the structure of the shredder consists of a lower box, an upper box, an inner partition, a knife shaft, a moving knife, a moving knife spacer, a roller bearing, It is composed of fixed knife, fixed knife fixed plate and corresponding sealing structure.

Crushing is a processing procedure of solid waste resource utilization. The double shaft shredder used in solid waste crushing tends to consider the output, quality and particle shape of the material to a great extent. What should be taken into consideration in selecting double shaft shredder equipment?
The user's choice of double shaft shredder should be determined by combining the properties of raw materials to be broken. Double shaft crusher equipment is widely used, it can crush domestic waste, kitchen waste, waste tires, large pieces of garbage and other materials, so we should choose the appropriate double shaft crusher equipment according to our common materials.
There are many specifications of double shaft shredder. Because the output value and investment cost budget of different specifications and models of double shaft crusher equipment are different, it is necessary to select and build the equipment with higher price as reasonably as possible according to the customer's requirements for the expected output value.
After sales service of double shaft shredder manufacturer. The price, quality and after-sales service of the equipment are the problems that users need to consider. Double shaft crusher is a kind of mechanical processing equipment, perfect after-sales service is the key factor to ensure normal production.
3 Differences between One and Two Shaft Shredder
When choosing an industrial shredder, the first question lots of the customers ask is what is the difference between single shaft shredder and double shaft shredder. One may not see the difference except their outlook, but they are very different in 3 points. In this article, we explain the differences between one shaft shredder and two shaft shredder.
Machine Structure
Single shaft shredder is equipped with only one shaft welded with rotary blades. The rotor a hydraulic-actuated pusher arm and a screen underneath the rotating shaft.
Double shaft shredder is built with two shafts of blades, which we also call dual shearing shafts. Its rotor consists of multiple disks of blades. The 2 rotors counter-rorate. There is no hydraulic-driven pusher or screen on this machine.
Application
Single shaft shredder is suitable to process thick and solid materials such as molding purgings, runners, sprues, plastic pallets, rubber rolls, wood lumbers, tree branches, bones, wood pallets, roll of films etc.
Double shaft shredder excels in shredding large and relatively light or hollow products, such car/truck tires, film, plastic/steel drums, scrap tv/computer, scrap fax/printing machines, etc. Also, a mixture of the material streams like msw can use double shaft shredder.
The output of both machines can go to secondary size reduction like granulator.
Operation Process
A single-shaft shredder, when the material is fed into the hopper, the pusher arm drives the material against the rotor, ensuring the material is efficiently in contact with and shredded by the rotary knives. The material will be repeatedly shredded till the shreds are small enough to pass throughput the screen. Therefore, you can get uniform output particles.
How to Maintain the Double Shaft Shredder?
The double-shaft shredder can shred waste products and other repair projects. To make uniform standards, convenient, and solve afterwards, the amount of waste can also be reduced. As everyone knows, this kind of equipment has different levels of wear in the internal crushing chamber and cutter head for long-term applications. This must maintain management methods on time. Let us talk briefly about this matter.
The inner lining belongs to the part of wear, and excellent wear resistance should be used to reduce the wear during the whole process of application. This is also a way to reduce maintenance and treatment. The excellent design plan can make the utilization rate of the crusher and prevent part of the wear. It can consume the kinetic energy of friction to migrate to the extrusion molding of the raw material. But it can reduce the wear of related parts. In addition, it can improve the high efficiency of electric energy and improve the overall characteristics.
Because of the large amount of production, the tearing machine must be regularly maintained and the equipment maintained. For the worn surface, do your lubrication to reduce the sliding friction between them to a more moderate level. In addition, the lubrication of rolling bearings and other parts can give full play to its excellent effects in equipment, and it can fully play a key role in reducing wear.
How Does a Double Shaft Shredder Help to Reduce Bulky Waste?
Waste management is one of the essential tasks that need to be done. But unfortunately, one of the biggest problems in the waste management industry is the need to dispose of hazardous waste. If not disposed of properly, this waste can be harmful to the environment and the people in the vicinity. As a result of this concern, the importance of recycling has become even more significant. This recycling is crucial to the environment and to industry. There have been a lot of discussions about how we can effectively deal with waste. Unfortunately, many of the solutions proposed are too expensive or are not sustainable. Then, there comes the concept of shredding.
Shredders are essential to recycling companies as they can efficiently recycle various materials, including scrap metal, aluminum, copper, brass, plastic, paper, wood, tires, and food waste. The twin shaft shredder machine is the most popular and widely used for recycling waste material recycling. The process of recycling waste material has become an increasingly important area of concern for many countries around the world.
A twin shaft shredder machine is a powerful tool for reducing bulky waste. The device has two rotating shafts with sharp blades that shred the waste into smaller pieces. This makes it easier to handle and dispose of the trash. The twin shaft shredder machine is also effective at reducing the volume of the waste, which can save space in landfills and other disposal methods. Twin shaft shredders are used to reduce large plastic materials like car bumpers, pipes, and storage drums into smaller pieces so they can be recycled. It is made of special hardened steel, which can be easily replaced.
The shredders work slowly to break the materials into smaller pieces. The pieces are then collected, washed, treated, and granulated for recycling. The heavy-duty shredder is ideal for receiving and tearing down large objects. The wide-open hopper and shredding chamber makes it easy to control the size of the material, resulting in 60mm by 60mm particles or stripes. It helps reduce the bulky materials’ size and weight, which decreases the overall time reduction.
