Description

The SOYU Twin-shaft industrial shredder (also known as a heavy-duty double shaft shredder) is a high-efficiency, low-speed, high-torque solution designed for heavy-duty volume reduction. Engineered for maximum energy saving, this industrial shredding machine starts at a power consumption of just 1.5kW without compromising performance.

Streamlined Dual-Shear Cutting Principle

Unlike screened units that are prone to clogging, this dual-shear shredder utilizes two counter-rotating blades to grab, tear, and pull material directly through the hopper for immediate discharge.
While providing a varied output size, the twin-shaft industrial shredder excels in:
  • High Processing Speed: Continuous feeding without material pushers.
  • Bulk Throughput: Significantly outperforms single-shaft models in high-capacity waste management.
  • Versatile Recycling Applications: Ideal for bulky waste, tangled materials, and heavy metals.

Applications:
    • Metal & Automotive: Car shells, metal drums, IBC tanks, and scrap steel/aluminum.
    • Tires & Rubber: Passenger car tires, truck tires, and OTR rubber waste.
    • Waste-to-Energy: MSW (Municipal Solid Waste), RDF/SRF production, and medical waste.
    • Electronics & Bulky Waste: E-scrap, household appliances, furniture, and mattresses.
    • Hazardous & Industrial: Hazardous industrial residues and complex solid waste.


    Features:

    Precision-Engineered Rotor and Heavy-Duty Blades
    At the heart of our twin-shaft industrial shredder is a high-strength rotor system designed for maximum shearing force.
    • Superior Material: Our blades are manufactured from CrMoV superior alloy steel, vacuum heat-treated to ensure exceptional toughness and wear resistance.
    • Optimized Cutting: The intermeshing blade arrangement allows the rotors to grab, tear, and shred large materials with ease.
    • HARDOX™ Wear Protection: To withstand high-abrasion environments, the shredding chamber is lined with HARDOX™ wear-resistant steel plates, significantly extending the machine’s service life and reducing maintenance costs.

    High-Performance Drive Train & Intelligent Control

    The SOYU twin-shaft industrial shredder features a robust drive train engineered for maximum operational stability and torque efficiency:
    • Flexible Drive Options: The machine integrates both high-efficiency electric motor and heavy-duty hydraulic drive options, allowing us to customize the power source to suit your specific material handling needs.
    • German Standard Engineering: The reducer and rotor are connected via German industrial standard DIN 5480 splined shafts. This precision-engineered connection ensures reliable torque transmission and exceptional durability under extreme loads.
    • Smart Automation: All operations are managed by a Siemens PLC-based control system. This intelligent interface features automatic fault detection and overload protection, ensuring safe, continuous operation and minimizing downtime.
    Advanced Hydraulic Ram for Twin-Shaft Industrial Shredders

    Maximize Throughput for Bulky & Hollow Materials
    While standard twin-shaft industrial shredders often struggle with materials that "float" or "bridge" in the hopper, the SOYU Hydraulic Ram (Pusher) system provides a definitive solution.
    • Optimized for Hollow Products: Specifically designed for processing large hollow products such as plastic drums, IBC tanks, car shells, and bulky containers. The hydraulic ram actively forces the material into the rotating blades, eliminating "slipping" and idle running.
    • Significant Throughput Improvement: By ensuring constant and controlled pressure on the rotors, the hydraulic pusher dramatically increases shredding efficiency and hourly output capacity compared to gravity-fed models.
    • Intelligent Integration: Our hydraulic processing ram is fully synchronized with the Siemens PLC. It automatically adjusts its feeding pressure and stroke speed based on the motor load, preventing jams and optimizing the power-to-output ratio.
    • Heavy-Duty Construction: Built to withstand intense impact, the ram ensures long-term reliability even when handling high-density industrial waste.

    Certified Quality & Premium Components

    SOYU machinery is built to the highest industrial standards. Our twin shaft shredders are ISO 9001and CE certified, ensuring maximum safety and performance. To guarantee 24/7 reliability, we integrate world-class components from industry leaders like Siemens, Schneider, and NSK into our drive and control systems.

    Q1: What materials are best suited for the SOYU twin shaft shredder?

    A: The SOYU twin shaft shredder is designed for heavy-duty applications. It is ideal for bulky and tough materials such as scrap metal, car tires, electronic waste (WEEE), large plastic drums, and MSW (Municipal Solid Waste). Its low-speed, high-torque shearing action ensures efficient size reduction for materials that single shaft shredders might struggle with.

    Q2: What is the main difference between SOYU single shaft and twin shaft shredders?

    A: The primary difference lies in the shredding mechanism. Single shaft shredders use a pusher and a screen to produce uniform, small particles. In contrast, SOYU twin shaft shredders use two interlocking cutting shafts to tear and shear materials into strips or irregular pieces. Twin shaft models are preferred for primary shredding of large, mixed, or high-strength waste.

    Q3: How do the cutting blades handle wear and tear in twin shaft models?

    A: Our blades are crafted from high-strength alloy steel (such as Cr12MoV or specialized imported steel) and undergo advanced heat treatment. For the SOYU twin shaft series, the blades are designed for durability; many models feature detachable or stackable blade configurations, allowing for easy individual replacement or sharpening, which significantly reduces maintenance downtime and costs.

    Q4: Can the output size be adjusted on a twin shaft shredder?

    A: Unlike single shaft shredders that use screens, the output width of a twin shaft shredder is primarily determined by the thickness of the cutter blades. However, the length of the shredded material can vary. If a specific, uniform particle size is required, we often recommend a multi-stage system where the twin shaft shredder acts as a primary crusher followed by a secondary granulator.

    Q5: Does SOYU provide customized blade configurations for specific materials?

    A: Yes. Depending on the material (e.g., tough rubber vs. brittle electronic boards), Shouyu Machinery (SOYU) offers different blade tooth numbers, thicknesses, and hook geometries. We provide customized shredding solutions and can perform material testing at our facility to ensure the blade configuration matches your specific throughput and size requirements.
