Single shaft shredder uses the interaction of movable cutter heads and fixed knives to tear, cut and extrude the material into small size. It can be available for shredding a wide range of materials including plastic, wood, rubber, and paper, etc. The cutter head is consists of basic shaft and pieces of quadrangle cutter. Four edges are easy to change. 'V' shaped rotary cutters are fixed on a single shaft. The fixed cutter is mounted at an angle adjacent to the rotary cutter to achieve better cutting. The material is grabbed between 'V' shaped rotary cutters and fixed cutter shreds repeatedly. During the grinding process, the evenly cutting, saving of energy and reducing of noise are ensured by the installation of 'V' shape rotor knives. Also, the knives are very easy to install and remove.

There’s a wide range of single shaft shredders available, each designed for different materials and applications. These shredders utilize different shredding techniques to efficiently break down various types of waste.
One common type is the rotary shredder, which features rotating blades that chop materials into smaller pieces. This type of shredder is often used in the recycling industry to process plastic, rubber, and wood waste.
Another type is the granulator shredder, which uses a combination of cutting and grinding to reduce materials into fine particles. Granulator shredders are commonly used in the plastic and paper industries, where precise particle size is crucial for production.
For applications that involve heavy-duty shredding, the single shaft industrial shredder is the ideal choice. This powerful machine can handle large volumes of waste, such as metal scrap, tires, and bulky plastics. It uses a single shaft with multiple blades to tear apart materials, ensuring efficient shredding and high throughput.
What Is the Difference Between Single Shaft Shredder and Double Shaft Shredder?
Machine Structure Is Different
Single shaft shredder is equipped with only one shaft with rotary blades, a hydraulic-driven pusher plate/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. There is no hydraulic-driven pusher or screen on this machine.
The Application Of Material Is Different
Single shaft shredder is mainly applied to shred thick and solid materials such as molding purgings/runners/sprues, plastic pallets, rubber rolls, wood lumbers, tree branches, bones, wood pallets, etc.
Double shaft shredder normally is used to shred small to large sized relatively light or hollow products, such car/truck tires, film, plastic/steel drums, scrap tv/computer, scrap fax/printing machines, etc.
Operation Process Is Different
With a single-shaft shredder, once the material is fed into the hopper, the hydraulic-driven plate/arm pushes the material towards the cutting shaft to ensure the material is efficiently shredded by the rotary cutting blades. The material will be repeatedly shredded until the shreds are small enough to pass throughput the screen mesh as output.
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 swallowed into the discharging chamber. The shreds are directly discharged after cutting without passing through any screen, so the size of shreds is quite random.
Our single-shaft plastic shredders use unique, square knives that are bolted securely onto a large, closed rotor in a staggered array. As the square rotor knives are mounted with the corners protruding, jagged-teeth knives are mounted within the cutting chamber that act as the stationary knives. Unlike plastic granulator machines that spin
at high speeds, single-shaft shredders are relatively quiet, slow cutting machines that spin between 60-100 rotations per minute. As material is fed into the shredder, a hydraulic assisted drawer pushes the material against the rotor where it will be :continuously cut until it reaches the desired size as designated by a screen filter that is
fitted beneath the cutting chamber. The material will continue to be shredded until it is small enough to fall through this screen filter.
As our single-shaft plastic shredder machines are often placed in front of the most demanding jobs, the frame and structure of our shredders use high-thickness sheets and tubular. The square knives are treatment strengthened and use only the highest quality SKD11 steel (D2 equivalent) to ensure against dulling. Depending the capacity you require, we offer a variety of standard single-shaft shredders for your choosing.
The plastic recycling machines we manufacture are made with usability in mind and our single-shaft plastic shredders are no different. You will find our plastic shredders to offer motorized access to the cutting chamber as well as motor assisted screen changes as standard equipment.
