Facing the global challenge of managing over 1.5 billion scrap tires produced annually, the dual-shaft tire shredder has emerged as a key solution. Designed specifically for scrap tire recycling, this equipment is not just a machine—it’s a crucial hub for the circular economy, transforming what was once “black pollution” into valuable reusable resources and driving significant progress in environmental protection and resource reuse.
I. Core Equipment: Definition and Technical Composition
A dual-shaft tire shredder is specialized equipment that integrates a dual-shaft shredding unit and a disc screening system. Its core lies in two counter-rotating shear systems that handle primary shredding, while the disc screen precisely separates acceptable and unacceptable materials. Unacceptable materials are automatically recycled for secondary shredding.
Key Technical Components:
Dual-Shaft Shredding Unit: Shafts rotate synchronously, using high-strength blades to shear and tear materials.
Mines and Construction Sites: Handles on-site scrap engineering tires to reduce transportation costs and environmental pollution.
(II) Processing Objects
It can efficiently process various scrap rubber products:
Scrap Tires: Passenger car tires, truck tires, engineering vehicle tires, motorcycle tires, etc.
Rubber Waste: Rubber seals, rubber hoses, rubber pads, and other scrap rubber products.
Other Rubber Components: Scrap industrial rubber parts, rubber conveyor belts, rubber soles, etc.
III. Working Principle and Process Flow
The workflow of a dual-shaft tire shredder exemplifies the perfect integration of mechanical engineering and intelligent control:
Material Feeding: Scrap rubber products are fed into the machine via a conveyor system.
Dual-Shaft Shredding: Shafts rotate synchronously, using high-strength blades to shear and tear the material for primary shredding.
Material Return and Screening: Shredded material enters the disc screen, which separates acceptable material with a particle size less than 2 inches; unacceptable material is automatically returned to the shredder via the return system for secondary shredding.
Finished Product Discharge: Acceptable material is discharged from the outlet, completing the shredding process.
This process ensures thorough shredding and uniform particle size, providing high-quality feedstock for subsequent sorting, magnetic separation, and rubber recycling processes.
IV. Core Advantages and Industry Value
(I) Core Advantages
Complete Shredding: The dual counter-rotating design and disc screen return system ensure uniform particle size and remove all unshredded material.
Energy-Efficient and High-Efficiency: Automatic material return eliminates manual sorting and rework, improving processing efficiency by 30% compared to traditional shredders while reducing energy consumption.
Durable: Blades are made of ASTM A532 Class III wear-resistant alloy; the machine body is welded from thick steel plates, suitable for processing hard materials like tire steel wires and cords, ensuring a long service life.
Intelligent Control: PLC control system enables automated operation, reducing labor costs and improving production stability.
Environmentally Friendly and Clean: Enclosed design and dust removal system effectively control dust and noise, meeting environmental requirements such as EPA Part 63 and OSHA 29 CFR 1910.1000.
(II) Industry Value
Promotes Industrial Upgrading: Helps transform the tire recycling industry from traditional models to industrialized and intelligent ones.
Promotes Resource Circulation: Enables efficient recycling of resources like rubber and steel wires, alleviating resource shortages.
Supports “Dual Carbon” Goals: Reduces environmental pollution from scrap tires and lowers carbon emissions.
Creates Economic Value: Drives the development of upstream and downstream industrial chains, creating jobs and economic benefits.
V. Technological Development Trends and Purchasing Recommendations
(I) Future Trends
Technological development of dual-shaft tire shredders will follow these trends:
Intelligentization: Integrates IoT and AI technologies to enable real-time equipment status monitoring, fault prediction, and remote diagnosis.
High Efficiency: Optimizes shredding processes and blade designs to further improve processing efficiency and reduce energy consumption.
Large-Scale and Modular: Meets large-scale processing needs while offering modular designs for easy maintenance and upgrades.
Green: Uses more environmentally friendly materials and processes to reduce the equipment’s life-cycle environmental impact.
(II) Purchasing Recommendations
When selecting a dual-shaft tire shredder, consider the following factors:
Processing Scale: Choose the appropriate model based on expected daily throughput.
Material Type: Different types of tires and rubber products may require different blade configurations.
Discharge Requirements: Select the appropriate screen based on downstream process particle size requirements.
Budget and Maintenance: Consider equipment purchase costs, operating costs, and maintenance expenses.
Brand and Service: Choose brands with proven technology, reliable quality, and comprehensive after-sales service to ensure stable equipment operation.
The dual-shaft tire shredder is more than just equipment—it’s a vital link connecting scrap tires to the circular economy. With its powerful shredding capabilities, efficient processing flow, and intelligent control system, it is reshaping the scrap tire recycling industry. As technology advances and the industry continues to grow, dual-shaft tire shredders will play an increasingly important role in promoting green development and achieving “dual carbon” goals, becoming a core driver of the circular economy.
