How to choose the shredder?

Recently, there are many customers to ask me how to choose the shredder? It is the long-term problem for every one who wants to buy shredder. And it is very important to recycling manufacturers to how to choose the shredder. So according to my experience, I write down this article. I hope it is helpful.

I. Application of shredder

Shredder is a machine that is mainly used to shred big-size material recycled. Most of customers who work on recycling industrial use crushers to crush material before the shredder are not used widely. So I want to add a new topic called the differences between crusher and shredder. Crusher crushes material by the way of high speed rotation and high inertia impact. This machine has a lot of features of high production, low cost and easy operation, etc when it crushes small and light material. But it can not crush big size and rigid material just depending on high speed rotation and high inertia impact. If you want to crush rigid and big size material, you need to choose the machine that has the features of low speed rotation and high torque. The way of improving the torque is that reduces motor power by gearbox to achieve it. And it is why every shredder is equipped with gearbox. On the contrary, the crusher is only driven by Pulleys and counterweight wheels.

II. Three classification methods of shredder

1. According to the number of shaft, it can be classified single shaft shredder, twin shaft shredder and four shafts shredder.
2. It can be classified two types according to the way of driving: electric motor drive method, hydraulic motor drive method
3. It also can be classified by material to shred. This classification method is a little complicate.
4. The shredder is used to shred rigid plastic material, such as plastic pipes, sheets, trash cans, plastic baskets, etc.
5. The shredder is used to shred soft plastic material such as film, ton bags, woven bags, etc.
6. The shredder is used to shred metal.
7. The shredder is used to shred twigs, trunks, stalks, etc.

III. How to choose the shredder?

How to choose the shredder after introducing the classification of shredder? Firstly, we should know about the purpose of using shredder. We need to know about the type of material, output capacity, the size of finished products, etc, and then our engineers can provide the correct type and model of shredder.

For instance, If I require that I want to shred the big-diameter pipes. So some machinery manufacturers will recommend me to choose single shaft shredder, some of them will recommend me to choose to twin shafts, even some of them will recommend me to choose four shafts, at the same time, some of them even recommend me to choose crusher. But at first, crusher can not crush big-diameter pipes. Because I told you reasons before. At the same time, we can not choose the four-shaft shredder too, because it is mainly used to shred thin-walled hollow container. And then we can make a comparison between single shaft and twin shaft. The twin shaft shredder is driven by two motors and two shafts. Its working principle is that it cuts material by rotating bite between blades.In this way, the material fed in must be within the tolerance range of the motor torque before it can be cut, or the machine will happen such problem as blocked or frequent forward and reverse. If you want to use twin shaft shredder to shred big-diameter pipes, you should use the great motor power to reach the best effect. The drive way of single shaft is the single motor structure. And its working principle is that the main shaft rotates and drives the silo to push material on the main shaft rotating by cylinder. And finally shred the material into pieces.

IV. Summary

About how to choose the shredder? You should choose the shredder according to the characteristics of material and the requirements of output. And according to your all requirements, our engineers can recommend correct types and mold to you. Jiangsu Lantai Machinery Co., Ltd has worked on this field many years, and it is specialized in producing shredder and it makes a progress every year. What’s more, it is also specialized in producing all kinds of plastic recycling machines such as PET/PP/PE recycling line, crusher, extruder, silo, mixer, etc. I hope this article is helpful for everyone who wants to buy shredder. By the way, if you have any questions or advice about this article or shredder, please contact me at any time. Thanks!
