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.
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.
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.
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.
With a double shaft shredder, once the material is fed into the machine, the two shafts of cutting blades hook the material and then bite it until it’s fully broken down into pieces. No intervention of pusher ram or screen. The irregular sizes of shredded particles directly fall to the collection bin/conveyor.
