Quad Shaft Shredder
Engineered with a low-speed, high-torque design, our quad-shaft shredder utilizes synchronous shearing and recirculating shredding technology to repeatedly process bulky or mixed waste down to a specified size, ensuring uniform and consistent output. Equipped with an interchangeable screen system, the discharge sizing can be adjusted to meet diverse material specs, making it ideal for plastics recycling, RDF/SRF production, manufacturing scrap, industrial waste, and bulky municipal solid waste (MSW). Featuring replaceable cutters, external bearing protection, a heavy-duty welded chassis, and a PLC-controlled auto-reverse system, this machine minimizes maintenance overhead while maximizing operational reliability during continuous, heavy-duty cycles.
Features
Featuring a synchronized main and auxiliary quad-shaft layout, this system creates a recirculating shredding mechanism that continuously shears and processes materials within the shredding chamber.
Featuring a replaceable modular design with individual blade structures, the cutters can be selectively replaced based on maintenance requirements, significantly reducing operational costs and allowing for versatile stacked configurations.
The interchangeable screen system represents a primary differentiator between quad-shaft and twin-shaft shredders. By controlling the discharge sizing through the screen, operators can adjust output to meet varying material and process requirements. The resulting output size ranges from approximately 30–150 mm, making it ideal for applications requiring uniform sizing, such as RDF / SRF production.
Screen Aperture & Output Size Reference
| Screen Aperture | Output Size |
|---|---|
| 40 mm | 40–60 mm |
| 60 mm | 60–90 mm |
| 80 mm | 80–120 mm |
| 100 mm | 120–150 mm |
Featuring an external bearing design that isolates the bearings from direct contact with materials, this system prevents liquid ingress while enhancing bearing durability and service life.
Constructed from thick steel plates with a robust welded design, the heavy-duty chassis features high vibration resistance, making it ideal for high-torque operations and continuous long-term runtime requirements.
Equipped with an intelligent PLC-controlled forward and reverse system, this machine offers multiple modes customizable to diverse operational requirements. In the event of material jamming or overloading, the system automatically triggers the reverse cycle to clear obstructions and protect the gearbox.
