In plastic recycling, RDF/SRF alternative fuel production, electronic waste processing, and solid waste reduction, getting a consistent, fine output size is critical to secondary processing efficiency. However, operational teams routinely face severe performance hurdles with conventional primary shredders:
Inconsistent Output Particle Size: Standard dual-shaft shredders primary-cut waste into strips or large chunks, leaving materials unsuitable for direct pelletizing, extruding, or optical sorting.
Frequent Rotor Jams & Overheating: High-density plastics, tough films, and synthetic textiles often melt, wrap around rotors, or overload standard machinery, causing frequent line stops.
High Maintenance Costs & Tool Wear: Processing abrasive materials quickly degrades cutters, resulting in excessive downtime and high replacement costs for full knife assemblies.
The ZAECOTECH Rotary Spiral Shredder is specifically engineered as a high-precision fine shredding solution, delivering controllable particle sizes in a single pass.
The heavy-duty rotor features a specialized spiral arrangement of cutting teeth. This design ensures that only a few teeth engage the material at any given moment, significantly reducing instantaneous shock loads, minimizing power consumption, and delivering continuous, smooth shearing action.
Durable, Wear-Resistant Materials: Fitted with imported high-alloy steel blades and wear-resistant liners for extended service life.Blades are repairable and reusable, maximizing their lifespan and lowering the total cost of ownership.
Equipped with customizable screen meshes (typically 20mm–80mm) and an intelligent hydraulic ram, material is systematically pushed against the rotating rotor. Unsized material stays in the shredding chamber until it passes through the screen, guaranteeing strict particle size uniformity for downstream equipment.
An integrated smart PLC system monitors motor amps and automatically triggers reverse rotor movement to clear overloads. Additionally, hydraulic screen opening mechanisms allow quick, tool-free screen replacements and easy maintenance access.
