In the used tire recycling industry chain, dual-shaft shredders play a crucial role. They not only solve the problems of oversized tires and incomplete shredding but also significantly improve the efficiency of the entire recycling process through intelligent design. This article will delve into the technical details, application scenarios, and industry value of this equipment.
What Is a Used Tire Dual-Shaft Shredder?
This dual-shaft tire shredder, specially designed for used tire recycling, integrates a dual-shaft shredding unit and a disc screening system. The dual-shaft counter-rotating shear system is responsible for shredding tires, while the disc screen accurately separates qualified and unqualified materials. Unqualified materials are automatically recycled for secondary shredding, significantly improving the efficiency of the entire tire shredding process and effectively solving issues such as oversized tire size and incomplete shredding.
Applicable Materials and Application Scenarios
Used tire dual-shaft shredders can handle various types of rubber products:
Used Tires: Passenger car tires, truck tires, construction vehicle tires, motorcycle tires, and other types of used tires
Rubber Waste: Rubber seals, rubber hoses, rubber mats, and other used rubber products
Other Rubber Components: Used industrial rubber components, rubber conveyor belts, rubber shoe soles, etc.
Whether it’s small passenger car tires or large construction vehicle tires, whether they are complete tires or preprocessed tire strips, this equipment can handle them efficiently, providing an ideal raw material form for subsequent steel-rubber separation and rubber powder production.
Working Principle and Operational Process
The working process of a used tire dual-shaft shredder mainly includes the following steps:
1.Material Feeding Waste rubber products are fed into the machine’s inlet, and the feeding system can be adjusted according to the type and size of the raw materials.
2.Dual-Shaft Shredding The dual shafts rotate synchronously, using high-strength blades to shear and tear the raw materials for initial shredding. The counter-rotating design ensures uniform material shredding, avoiding blockages and excessive wear.
3.Return Material Screening Shredded materials enter the disc screen, which separates materials with qualified particle sizes. Unqualified materials are automatically returned to the shredder for secondary shredding through the return system, eliminating the need for manual sorting and rework.
4.Finished Product Discharge Qualified materials are discharged from the outlet, completing the shredding process. The finished material has uniform particle size, providing an ideal raw material for subsequent processing.
The entire process is highly automated, requiring only a small number of operators to monitor the entire system, greatly reducing labor costs and operational risks.
Core Advantages and Technical Features
Used tire dual-shaft shredders have the following notable features:
Complete Shredding: The counter-rotating dual-shaft design and disc screen return system ensure uniform material particle size and remove all unshredded materials, resulting in a high pass rate of finished products.
Energy-Efficient and High-Efficiency: The automatic return system eliminates the need for manual sorting and rework, improving processing efficiency by 30% compared to traditional shredders, with lower energy consumption.
Durable: Blades are made of wear-resistant alloy, and the machine body is welded with thickened steel plates, suitable for processing hard materials such as tire steel wires and cords, ensuring a long service life.
Intelligent Control: Equipped with a PLC control system, it can monitor the equipment’s operating status in real time, adjust shredding parameters, and optimize shredding results.
Safe and Reliable: Multiple safety protection devices are provided, including overload protection, temperature monitoring, and emergency stop systems, ensuring the safety of operators and equipment.
Easy to Maintain: The modular design facilitates daily maintenance and component replacement, with key components that can be quickly disassembled and installed, reducing downtime.
Industry Value and Environmental Significance
Used tire dual-shaft shredders not only improve the efficiency of used tire recycling but also bring significant environmental and economic value:
Resource Recycling: Through efficient shredding, more rubber and steel wires can be recycled, reducing dependence on primary resources. For every ton of used tires processed, approximately 0.75 tons of rubber and 0.12 tons of steel wire can be recovered.
Environmental Protection: Avoids improper disposal of used tires, reducing the risk of soil and water pollution. The shredding process is carried out in a closed environment, reducing dust and noise pollution.
Economic Benefits: Improves the efficiency and output quality of subsequent processing, increasing the market value of recycled products. Compared with traditional shredding processes, operating costs are reduced by approximately 20%.
Policy Compliance: Complies with national policies and requirements for used tire management and circular economy, helping enterprises obtain relevant subsidies and support.
Industrial Upgrading: Promotes the “recycling-shredding-remanufacturing” model, promotes the application of recycled materials in construction, transportation, agriculture, and other fields, and drives the development of related industry chains.
Technological Evolution and Future Trends
As used tire recycling technology continues to advance, dual-shaft shredders are also developing toward greater intelligence and efficiency:
Intelligent Control: Introduces AI visual recognition and intelligent control systems to realize automatic identification of raw material types and automatic optimization of shredding parameters.
Energy Efficiency Improvement: Adopts frequency conversion drive and energy recovery technology to further reduce energy consumption and improve operational efficiency.
Data-Driven Management: Through the Internet of Things and big data technology, realizes real-time monitoring of equipment status, fault early warning, and predictive maintenance.
Modular Design: Facilitates configuration and upgrading according to different processing scales and raw material types, adapting to diverse needs.
Automated Integration: Seamlessly integrates with subsequent steel-rubber separation equipment, magnetic separators, and rubber grinding machines to achieve fully automated processes.
Conclusion
The used tire dual-shaft shredder is not just a piece of equipment but a key link in the used tire recycling industry chain. With its powerful shredding capability and efficient workflow, it paves the way for subsequent processing and contributes to the circular economy and sustainable development. In today’s increasingly resource-constrained world, such technological innovations are particularly important.
