Heavy-Duty Rubber Shredder

Product Introduction

Rubber waste is notoriously difficult to process. Whether it's steel-reinforced conveyor belts, thick industrial mats, sticky rubber profiles, or end-of-life tires, standard grinding equipment struggles. Hammermills overheat from the friction, single-shaft shredders wrap and choke, and blade wear is punishingly fast. If your machine can't handle the mix, your processing line grinds to a halt.

Our Heavy-Duty Twin-Shaft Rubber Shredder is purpose-built to chew through the widest range of rubber waste without complaint. Using low-speed, high-torque shearing blades, it rips apart vulcanized rubber, cuts embedded steel cords, and processes sticky synthetics — all without sparking, melting, or jamming. From whole car tires to conveyor belts and molded parts, one machine delivers uniform, ready-to-process shreds for downstream grinding, pyrolysis, energy recovery, or direct sale.

Product Features

Twin-Shaft, High-Torque Shearing Two counter-rotating shafts fitted with thick alloy blades operate at very low speed (12–25 rpm), generating enormous shear force. This action cleanly cuts through resilient rubber, synthetic polymers, and embedded steel reinforcements without the friction heat and spark risk of high-speed grinders.

Steel Wire & Fiber Tolerant Many rubber products contain steel cord or nylon fabric. Our blade profile and shaft design cut these materials rather than wrapping them. Steel wire is sheared into short segments that can be easily removed by a downstream magnetic separator. This makes the machine ideal for conveyor belts, reinforced hoses, and tires.

Anti-Jam & Auto-Reverse Intelligence The PLC control system continuously monitors shaft torque. Upon detecting an overload or hard foreign object, the rotors automatically reverse to eject the obstruction, then resume forward rotation — all within seconds and without operator intervention. This keeps production flowing on mixed, unpredictable feedstock.

Long-Life, Re-Sharpenable Cutting System Blade segments are precision-machined from high-alloy, through-hardened tool steel. Their thick profile withstands heavy impacts and accepts multiple re-sharpening cycles. Quick-release access covers allow fast blade rotation or replacement, keeping maintenance intervals short and throughput high.

Precise Output Size Control Interchangeable sizing screens are supported by a hydraulic cradle for rapid, tool-free changes. Screen hole diameters range from 15mm to 80mm, allowing you to produce the exact chip size required for crumb rubber lines, pyrolysis feed, TDF, or molding applications.

Applicable Material

Rubber Materials We Shred

Tires of All Types: Car, truck, OTR, and agricultural tires. Whole or pre-cut. Steel bead and sidewall wires are sheared cleanly — no debeading required for passenger car tires.
Conveyor Belts: Fabric-reinforced and steel-cord conveyor belts. Rip-resistant and high-tensile belts are reduced to manageable, uniform chips for fuel or reclaim.
Rubber Matting & Flooring: Heavy industrial mats, gym flooring, anti-fatigue mats, and rubber tiles. Thick, dense rubber is no match for twin-shaft torque.
Rubber Profiles & Extrusions: Automotive weather seals, window gaskets, hose sections, and extruded bumper strips. Low-speed cutting avoids softening and wrapping common with sticky EPDM and synthetic blends.
Molded Rubber Parts: Engine mounts, rubber-to-metal bonded bushings, suspension bump stops, and shoe soles. Efficiently reduces bulk and liberates metal inserts.
Industrial Rubber Scrap: Offcuts from rubber sheet production, vulcanized scrap, rejected bellows, and composite rubber-plastic parts.

Why Choose Us

Factory-Direct Engineering: When you contact us, you speak with the engineers who design and build the shredders. We manufacture core assemblies — rotors, gearboxes, PLC controls — in our own facility, which means rigorous quality control and direct pricing with no added intermediary costs.
12-Month Comprehensive Warranty: All major mechanical and electrical components are covered. Our remote support team responds within 12 hours to provide video-guided diagnosis and repair instructions, getting you back online fast.
Fast-Response Spare Parts & Straightforward Advice: We stock a full inventory of wear items (blades, spacers, seals, screens) and dispatch them without delay. Our maintenance guidance is grounded in real-world data — we show your team how to maximize blade life and plan service, not how to overspend on parts.
Turn-Key Rubber Recycling Systems: Beyond the shredder, we engineer and integrate complete lines — magnetic separation, secondary granulation, fiber removal, and bagging. One partner from engineering to commissioning simplifies your project and ensures every component works together.

FAQ

Can this shredder handle both tires and industrial rubber without changing settings? Yes. The twin-shaft design and PLC load-sensing feed mean the machine adapts automatically to varying material densities and toughness. You can feed a mix of tires, conveyor belts, and molded parts without constant adjustments.

What happens to the steel wire inside the rubber? The shearing action cuts the steel wire into short lengths. These can then be separated downstream by a magnetic separator. The rubber shreds come out relatively clean, ready for further processing.

Does the machine overheat with sticky synthetic rubber? No. The low rotational speed (12–25 rpm) generates minimal frictional heat. Sticky rubbers that would melt and gum up in a high-speed grinder are cut cleanly without heating up to softening temperatures.

How often do blades need re-sharpening? For mixed rubber waste, including tires with steel, expect 400–800 working hours between sharpening cycles. Clean industrial rubber offcuts can extend this interval significantly. Blades can be re-sharpened 5–7 times before replacement.

What output sizes can I get? By changing the sizing screen, you can produce chips from approximately 15mm up to 80mm. We supply multiple screen sizes so you can tailor output to your downstream process — be it crumb grinding, pyrolysis, or TDF.

Do you support overseas installation? Yes. We provide detailed engineering drawings, 3D layout files, and step-by-step installation and commissioning videos. We can also send engineers to your site for hands-on startup and operator training.
