A Spiral Shredder for Soft Material Recycling provides an efficient solution for processing flexible and fibrous waste such as plastic films, textile waste, soft plastics, packaging materials, and RDF. Unlike rigid materials, soft waste can easily wrap around cutting components, form irregular bundles, and create unstable feeding conditions.
For recycling plants that require continuous processing and controlled particle sizes, a properly designed spiral shredder can improve material handling, size reduction, and downstream recycling efficiency.
Soft materials have different physical characteristics from rigid waste, creating several challenges during shredding.
Plastic films, textiles, and similar materials can deform instead of breaking immediately under pressure. This makes stable cutting more difficult.
Long and flexible materials may wrap around the rotor if the cutting system is not properly designed, affecting continuous operation.
Soft waste is often supplied in loose, bulky, or mixed forms. Inconsistent feeding can influence shredding performance and final output.
Recycling and RDF production often require a relatively consistent particle size for downstream screening, separation, or fuel preparation.
These challenges make cutting performance, material pushing, and output control important when selecting shredding equipment.
The ZAECOTECH Spiral Shredder, also known as a Single-shaft Rotary Shredder, uses dynamic blades mounted on the main shaft together with fixed blades installed on the machine body.
During operation, the low-speed rotating shaft repeatedly cuts the material while pushing it through the cutting chamber. The material is continuously sheared and shredded before reaching the discharge section. A screening system helps control the final particle size.
The interaction between dynamic and fixed blades provides repeated cutting instead of relying on a single crushing action.
The rotating main shaft helps move materials through the chamber while they are being processed, supporting continuous feeding and shredding.
The shredding system uses adjustable screening to help produce a more consistent output. ZAECOTECH lists an adjustable output range of 20–100 mm for this ultra-fine model.
The equipment is designed for industrial applications where stable processing and consistent output are more important than simple volume reduction.
A Spiral Shredder can be integrated into recycling systems for different types of flexible and light materials.
Waste plastic films and flexible plastic materials can be reduced into smaller fractions for subsequent recycling or sorting.
Textile scraps, fibers, and other fabric waste can be shredded before further processing or resource recovery.
Packaging waste can be size-reduced to improve transportation, sorting, and downstream processing.
The shredder can also be used for secondary processing of pre-shredded waste to prepare more uniform alternative fuel feedstock.
The product page specifically identifies plastics, textiles, and RDF as application materials for the ultra-fine single-shaft rotary shredder.
A typical soft material recycling process can be arranged as:
Soft Waste → Feeding → Spiral Shredding → Screening → Uniform Output → Recycling or RDF Production
The Spiral Shredder can serve as a secondary size-reduction unit within a larger recycling system. After shredding, the more consistent material size can make subsequent screening, separation, blending, or fuel preparation easier.
For example, in an RDF production system, the shredder can refine pre-shredded waste and provide controlled output for alternative fuel preparation. ZAECOTECH reports an RDF application using the machine as a secondary processing unit with a 30 mm output and an 8–12 t/h processing rate.
Controlled shredding and screening can help produce a more uniform material size for downstream processing.
Reducing bulky soft waste makes storage, transportation, and conveying easier.
The combination of main-shaft cutting and material pushing supports continuous industrial operation.
More consistent feedstock can benefit screening, sorting, RDF production, and other recycling processes.
The machine can be configured according to material characteristics, required capacity, output size, and site conditions.
Choosing the right machine requires more than simply looking at the rated capacity.
Tell the supplier whether the material is plastic film, textile waste, soft packaging, RDF, or mixed waste. Different materials may require different cutting configurations.
The ZAECOTECH ultra-fine single-shaft rotary shredder is listed with a capacity range of approximately 1–15 t/h, depending on the model and operating conditions.
Determine the required particle size before selecting the screen. The listed output range is adjustable from 20–100 mm.
Material size, feeding method, moisture content, and material composition can all influence actual processing performance. The manufacturer's published capacity data notes that actual throughput may vary according to these factors.
The final application should also be considered. A recycling line, RDF system, or material recovery process may require different output specifications.
ZAECOTECH's Spiral Shredder is designed for applications requiring controlled and relatively fine output. The product range includes multiple models, with published capacities from 1–15 t/h depending on configuration. The company also provides customized equipment based on material type, capacity, and site conditions.
For soft material recycling projects, the key advantage is not simply reducing waste size, but producing a more manageable and consistent feedstock for the next processing stage.
