Product Description
Our heavy-duty double-shaft shredders are a perfect addition to our standard PP / PE film washing line especially for washing plants requiring larger capacities. This low-speed, high-torque machine is used primarily to “pre-cut” entire bales of PP/PE film at volume speeds.
At the core of the double-shaft shredder are shear blades mounted on 2 hexagonal shafts that rotate into each other producing a cutting / shredding motion. These hooked styled shear blades allowing the shredder to quietly shred high volumes of PP / PE film into random, smaller pieces between 1-5 inches. The low speed of the rotors also ensures that little or not dust is generated.
As our double-shaft shredders are usually placed in front of the most demanding jobs, the frame and structure of our shredders use high-thickness sheets and tubular. The shear blades 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 double-shaft shredders for your choosing.
For solid, thick pieces such as plastic purging, runners, or pallets, our single-shaft shredder is the better choice — the double-shaft design here excels at high-volume, hollow and film materials.

Frequently Asked Questions
How does a double-shaft shredder work?
At the core are hooked shear blades mounted on two hexagonal shafts that rotate into each other, producing a cutting and shredding motion. This low-speed, high-torque design pre-cuts entire bales of PP/PE film into random smaller pieces between 1–5 inches. The slow rotor speed also means little or no dust is generated during shredding.
What materials is the double-shaft shredder best for?
It is used primarily to pre-cut entire bales of PP/PE film at volume speeds — high volumes of hollow, light-weight film materials. It is a perfect addition to a standard PP/PE film washing line for plants that need larger capacities, sitting ahead of the crusher and washing stages.
Where does the double-shaft shredder fit in a recycling line?
It is typically the first machine in a film washing line: whole bales go in, and 1–5 inch pre-cut pieces come out, ready for the crusher, friction washers, and sink-float separation. Pre-cutting bulky bales upfront keeps every downstream stage fed at its rated capacity.
What models and capacities are available?
The standard range runs from the SSJ400-800 (2×22 KW motors, 1,500 KG/H) and SSJ400-1200 (2,500 KG/H) up to the SSJ450-800 (3,000 KG/H) and SSJ450-1200 (2×45 KW motors, 4,000 KG/H). Rotor speeds range from 18–35 RPM depending on the model, and other configurations can be offered based on your capacity needs.
What are the lead times for ordering?
The lead time for a single piece of equipment is 30 days from the signing of the purchase contract. For custom orders such as complete washing lines, the lead time is between 60–90 days. Actual lead times depend on the project’s complexity and factory availability.
What maintenance does a double-shaft shredder require?
The shear blades are treatment-strengthened and use high-quality SKD11 steel (D2 equivalent) to ensure against dulling, and the frame uses high-thickness sheets and tubular steel for demanding jobs. Inspect blades regularly and follow our blade replacement guide — preventive checks keep this high-throughput first stage running without interruption.
