Product Overview
The DAKY Dual Shaft Shredder is a high-efficiency solid waste volume reduction machine composed of blades, main shaft, fixed knives, load-bearing box, box frame, feeding system, power system, and electrical control system. It is widely applicable to various unprocessed raw materials or offcuts. Through dual-shaft coordinated shearing and shredding, it reduces large pieces into fine fragments, providing reliable pretreatment for subsequent recycling, sorting, and refinement. From scrap car shells, large plastic drums, and waste tires to metal offcuts, municipal waste, wooden pallets, and bulk bags — over 100 material types can be efficiently shredded.
Core Advantages
Heavy-duty high-efficiency shredding, designed for volume reduction of large hard materials.
- Heavy-Duty Structure, Lasting Stability: The main body is integrally welded from quality steel plate, with strong impact resistance ensuring stable long-term heavy-load operation.
- High Wear-Resistant Blades, Extended Service Life: Moving blades forged from special alloy tool steel with precision machining, multi-stage heat treatment and cryogenic processing — service life 50%+ longer than standard blades.
- Split-Type Structure, Hassle-Free Maintenance: Innovative split-type bearing housing design allows quick removal of blades, fixed knives, and bearings without complex tools.
- Powerful Shafts, Efficient Shredding: High-strength heavy-duty steel shafts with differential dual-shaft operation generate powerful shearing and tearing force for large hard materials.
- Flexible Blade Customization: Blade thickness available in 15mm–100mm; claw quantity and arrangement customizable to match different material characteristics.
