Single Shaft Shredder is designed for efficient size reduction of plastics, wood waste, rubber, textile scraps, RDF, electronic waste, and light metal materials, municipal solid waste, industrial waste, etc. It uses a high-torque rotor equipped with replaceable cutting blades and a hydraulic feeding system to efficiently shred materials against a stationary counter knife. A built-in screen controls the final output size, ensuring consistent particle dimensions for downstream processing.
Kowloon Machinery Single Shaft Shredders can be customized according to material characteristics, required output size, and production capacity, ensuring optimal performance for different recycling applications.
Common materials processed by a Single Shaft Shredder include:
1. Plastic Waste: Plastic drums, HDPE containers, PET bottles, plastic pipes, plastic pallets, injection molding scraps, plastic lumps, and plastic films.
2. Wood Waste: Wood pallets, furniture waste, plywood, MDF boards, tree branches, wooden crates, and construction wood scraps.
3. Textile Waste: Fabric scraps, carpets, nonwoven materials, clothing waste, and industrial textiles.
4. Municipal & Industrial Waste: RDF, commercial waste, packaging waste, bulky waste, and general industrial refuse.
5. Light Metal Scrap: Aluminum profiles, aluminum cans, thin metal sheets, and mixed non-ferrous materials.

Single Shaft Shredder works by using a high-torque rotor equipped with replaceable cutting blades to reduce materials into uniform-sized particles. Materials are fed into the shredding chamber through the hopper, where a hydraulic ram continuously pushes them toward the rotating shaft for efficient cutting and tearing against a stationary counter knife. Once the materials are shredded, they pass through a screen that controls the final output size, ensuring consistent particle dimensions. The processed material is then discharged for further recycling operations such as washing, granulating, sorting, or fuel production. This controlled shredding process provides high efficiency, uniform output, and reliable performance for processing plastics, wood waste, light metal, textiles, RDF, and various industrial waste materials.
With years of experience in recycling equipment manufacturing, Kowloon Machinery provide customized shredding solutions tailored to different materials, capacity requirements, and production goals.

Automatic overload protection system detects excessive loads and activates protective measures to prevent damage to the motor, rotor, and other critical components, improving equipment reliability and lifespan.
Equipped with a PLC-controlled system, emergency stop buttons, safety cover sensors, and automatic shutdown functions, the Single Shaft Shredder provides comprehensive protection for operators and ensures safe operation in demanding recycling environments.
High-quality alloy steel blades offer excellent wear resistance and cutting performance, enabling the machine to process tough materials efficiently while reducing blade replacement frequency and maintenance costs.
Built with a reinforced steel frame and heavy-duty shredding chamber, the machine is designed to withstand continuous industrial use and deliver reliable performance over a long service life.
Its compact structure requires less floor space compared to larger shredding systems, making it suitable for recycling plants with limited installation areas while maintaining high processing efficiency.
The low-speed, high-torque rotor design delivers powerful shredding performance while consuming less energy, helping reduce operating costs during long-term production.
The modular design allows quick access to key components, making routine maintenance, blade replacement, and equipment inspection more convenient and reducing overall downtime.
With an integrated screen system and controlled shredding process, the Single Shaft Shredder produces uniform material sizes that are ideal for subsequent recycling operations such as washing, granulating, sorting, pelletizing, or RDF production.
