Description

Advanced Four-Shaft Shredding Technology:
  • High Efficiency: The innovative four-shaft structure combines primary and secondary shredding into a single pass, maximizing operational efficiency.
  • Uniform Output: Integrated sizing screens ensure a precise and consistent final particle size.
  • Heavy-Duty Performance: Low-speed, high-torque drive system easily handles bulky and tough materials.

Applications:
  • Plastic Recycling: Plastic buckets, pallets, HDPE drums, and flexible film.
  • Metal Processing: Aluminum profiles, pop-top cans, and light metal scrap.
  • E-Waste (WEEE): Circuit boards (PCB), hard drives, and household appliances.
  • Industrial Waste: Paper mill rejects (ragger tails), medical waste, and RDF production.


Core Components:

Rotor & Blades
  • "V" Spiral Configuration: The four-shaft structure features a "V" spiral blade arrangement, delivering balanced cutting forces and superior shredding uniformity.
  • Self-Cleaning Synergy: Integrated auxiliary shafts provide continuous cleaning of the main cutters, preventing material buildup and ensuring smooth processing of flexible materials.
  • Premium Wear Protection: Both sidewalls are reinforced with HARDOX wear-resistant steel liners, providing exceptional durability against high-impact and abrasive loads.

Hydraulic Ram System
  • Optimized Feeding: Specifically engineered for large, hollow, and bulky objects, the intelligent hydraulic ram ensures consistent material contact with the cutting shafts.
  • Maximum Throughput: By maintaining optimal pressure, the ram system significantly boosts processing efficiency and eliminates material "bouncing."
Control & Sizing System
  • Intelligent PLC Logic: Equipped with a SIEMENS PLC system, providing real-time monitoring, automatic fault detection, and integrated overload protection.
  • Precision Sizing Screen: The integrated screen ensures a precise and consistent final particle size. Its user-friendly design allows for quick disassembly and replacement to meet different output requirements.
  • Premium Components: All critical electrical components are sourced from globally recognized brands to ensure long-term stability and global serviceability.

FAQ for SOYU Four Shaft Shredder

Q1: What are the main advantages of a SOYU four shaft shredder?

A: The SOYU four shaft shredder combines the benefits of both single and twin shaft models. Its key advantages include superior grabbing ability for bulky materials (like IBC tanks and drums) and integrated screening. Unlike a twin shaft, the four shaft design allows for a screen to be installed, ensuring that the output material reaches a specific, uniform size in a single pass.

Q2: How does the four shaft shredder control the output particle size?

A: At Shouyu Machinery (SOYU), our four shaft shredders are equipped with a detachable screen located beneath the cutting shafts. Materials are continuously shredded by the four sets of blades until they are small enough to pass through the screen holes. This makes it an ideal solution for applications requiring strict output size control without needing a secondary granulator.

Q3: What materials is the SOYU four shaft shredder best suited for?

A: This series is perfect for bulky, hollow, or mixed waste. Typical applications include IBC tanks, plastic blue drums, E-waste (WEEE), car bumpers, wood pallets, and light metal scraps. The two auxiliary shafts help to actively grab and feed the material into the main cutting shafts, preventing material from "bouncing" on the blades.

Q4: Can the blades of the SOYU four shaft shredder be maintained easily?

A: Yes. SOYU designs its four shaft series with maintenance in mind. The blades are made from high-strength alloy steel and can be individually replaced or refurbished. Our unique modular chamber design allows for faster access to the shafts, reducing downtime during blade inspection or replacement.

Q5: Is a four shaft shredder better than a twin shaft shredder for E-waste?

A: For E-waste (WEEE) recycling, a four shaft shredder is often preferred if you need a consistent fraction size for downstream sorting (like magnetic or eddy current separators). While a twin shaft is great for primary volume reduction, the SOYU four shaft shredder provides the precise sizing needed to improve the efficiency of the entire metal recovery line.
