Secondary Shredder

The Precision Reduction Stage for Refined Rubber Output

Secondary shredders provide the critical final size reduction in tire recycling operations, transforming coarse rubber chips into uniform 10-50mm granules suitable for downstream applications. These high-speed systems combine precision cutting with advanced separation technology to produce clean, market-ready rubber product.

Engineered for Controlled Granulation

Featuring a high-torque, single-shaft design with rotor speeds of 150-400 RPM, the secondary shredder utilizes a combination of fixed and free-swinging hammers to progressively reduce material. The cutting chamber incorporates replaceable wear plates and specially shaped impact tools that create optimal particle-on-particle contact for efficient size reduction. The system's forced discharge design ensures consistent throughput while preventing heat buildup.

Advanced Particle Control Technology

The shredder employs a multi-stage screening process with adjustable grate openings to precisely control final particle size distribution. Integrated air classification removes residual fiber while magnetic separation captures any remaining steel fragments. Some models incorporate near-infrared sorting to separate different rubber compounds during the shredding process.

Operational Advantages

The secondary shredder achieves up to 80% reduction in energy consumption compared to primary processing, thanks to optimized cutting geometry and material preconditioning. The system maintains product consistency within ±2mm of target size, with less than 5% fines generation. Water-cooled bearings and shafts allow continuous operation without thermal degradation of rubber materials.

Maintenance for Quality Output

Tool rotation should be performed every 150-200 operating hours to maintain cutting efficiency. Screen inspection and replacement occurs every 500-800 hours depending on material abrasiveness. Monthly vibration analysis helps predict bearing failures before they occur. Modern systems feature automatic gap adjustment that compensates for tool wear in real-time.
