TL Four-Shaft Shredder – Industrial Heavy-duty Universal Shear Shredding Equipment for Solid Waste, Metal and Plastic
Developed for high-end working conditions of large-scale solid waste disposal and renewable resource dismantling, the Tenglong TL four-shaft shredder is the top-tier heavy-duty shredding host of the TL series. Equipped with a exclusive four-shaft differential speed planetary transmission structure and gradient dual-motor power configuration of 15kW–44kW, it is specially adapted to difficult-to-process mixed materials such as automobile dismantling waste, hazardous waste, electronic waste, large plastic and metal scraps. Featuring three core performances of low speed & high torque, intelligent anti-jam electric control and heavy-duty thickened cutter group, it has stronger anti-winding capacity and shredding force with lower operation and maintenance costs compared with traditional dual-shaft shredders. Suitable for 24-hour heavy-duty mass production in factories, it is the standard industrial heavy-duty four-shaft shear shredding equipment for large-scale renewable industrial parks and hazardous waste disposal centers.
- Gradient Model Detailed Parameters, Matching Shredding Capacity and Material Volume
The full series of four-shaft shredder are developed hierarchically according to material hardness, shredding volume and daily processing tonnage, with gradually upgraded cutter thickness, rotor diameter and fuselage bearing capacity, covering all scenarios from small auto repair factories to 10,000-ton-level solid waste industrial parks. All models adopt independent dual-motor drive. The complete model parameters are as follows:
| Model | Total Dual-motor Power | Crushing Cavity Size | Rotor/Cutter Specification | Machine Weight | Daily Shredding Capacity | Applicable Scenarios |
| TL8040/TL8060 | 15–22kW Entry Model | 800mm Standard Cavity Width | 18.5mm Standard Cutter Body | 1600–1800kg | Within 5 tons/day | Small and medium-sized renewable factories, small auto repair and dismantling factories |
| TL8080 | 30kW Standard Mainstream Model | 800×800mm Extended Cavity | 42-piece cutter arrangement, 22mm thickened cutter body | 2800kg | 5–15 tons/day | Mainstream renewable resource factories, universal shredding for mixed miscellaneous materials |
| TL9080/TL90100 | 37kW Medium and Large Heavy-duty Model | 900×800/1000mm Widened Cavity | 284mm large-diameter rotor, 25mm thickened cutter body | 3500–4200kg Heavy-duty fuselage | 15–25 tons/day | Whole household appliance shredding, medium-sized automobile dismantling, medical solid waste centers |
| TL100120 | 44kW Flagship Top-tier Model | 1000×1200mm Super-large Cavity | 320mm thickened rotor, 40mm ultra-thick impact-resistant cutter body | 6000kg Ultra-heavy-duty fuselage | Over 25 tons/day (whole vehicle shredding) | 10,000-ton-level solid waste industrial parks, dedicated line for end-of-life vehicle primary shredding |
- Core Advantages of Four-shaft Planetary Transmission, Outperforming Traditional Dual-shaft Shredders
2.1 Four-shaft Staggered Differential Shredding, Eliminating Material Winding and Cavity Blockage
The four-shaft shredder completely solves the fatal pain points of dual-shaft shredders. Four main shafts are equipped with independent planetary gearboxes for linkage with differential speeds, forming bidirectional staggered pulling and shearing force. Vehicle wiring harnesses, woven films, long strips of plastic and fine metal wires can be instantly cut and separated with almost no winding, jamming or cavity blockage failures. Large thick-walled materials are bitten and crushed under four-sided force, with far higher shredding efficiency and continuous operation rate than dual-shaft shredders of the same power.
2.2 Low-speed & High-torque Operation, Low Noise & Anti-vibration for Better Environmental Protection
The full series outputs peak shear torque at a constant ultra-low speed of 16–25rpm, shredding materials by physical shearing instead of high-speed impact crushing, with extremely low fuselage vibration and operating noise. The fuselage is integrally welded with thickened manganese steel and matched with an integrated heavy-duty shock-absorbing base, ensuring no shaking or deformation during 24-hour full-load shredding. It adapts to factory closed noise reduction operation and easily meets the environmental noise standards of solid waste plants.
2.3 High-alloy Thickened Cutter Group, Repairable and Reusable with Controllable Consumable Costs
The four-shaft shredder is equipped with factory-customized heavy-duty high-strength alloy steel cutters. The cutter thickness is gradiently upgraded from 18.5mm to 40mm according to models, featuring high hardness, impact resistance, corrosion resistance and chipping resistance, suitable for mixed crushing of metal, glass and hard plastic. Worn and passivated cutters can be directly repaired by surfacing welding and reused repeatedly without replacing the entire cutter shaft group, greatly controlling long-term costs of cutter procurement, operation and maintenance under heavy-duty working conditions.
- Siemens PLC Fully Automatic Electric Control, Industrial Three-level Safety Protection System
3.1 Intelligent Overload Automatic Reverse Anti-jam Function
The four-shaft shredder adopts original Siemens PLC programmable control system with a built-in high-precision current detection module. When thick steel plates, hard objects or oversized materials jam the cutter shaft, the system identifies overload within milliseconds and automatically reverses the main shaft to discharge blocked materials, then resets to forward operation automatically after material dredging. The whole process requires no manual disassembly or prying, without interrupting the entire dismantling production line rhythm.
3.2 Three-level Industrial Safety Lock for Compliant Mass Production
The four-shaft shredder is equipped with three major protections: motor overload power-off protection, maintenance door opening interlock power-off and external emergency stop button. The original control cabinet has a built-in fault code self-inspection function for quick positioning of electrical and transmission faults, enabling efficient maintenance. Adopting full sets of first-class international electrical components, it adapts to harsh factory conditions of humidity, dust and voltage fluctuation with extremely low failure rate during 24-hour continuous operation, fully complying with safety production specifications for solid waste disposal.
- Widely Adaptable Shredding Materials & On-site Recycling Scenarios
4.1 Full-range Shreddable Materials
Plastics: Hollow chemical barrels, automotive plastic interiors, large plastic frames, thick-walled PP/PE parts, packaging winding films, oversized defective injection-molded large parts;
Metals: Thin iron sheets, aluminum and copper scraps, end-of-life vehicle bodies, automobile chassis girders, household appliance metal frames, hardware waste components;
Solid & Hazardous Waste: Medical waste materials, electronic circuit boards, optical discs, industrial paper rolls, thick cardboard, mixed glass waste.
4.2 Applicable On-site Scenarios
End-of-life vehicle dismantling plants, large household appliance renewable industrial parks, designated medical hazardous waste disposal centers, electronic waste recycling and sorting bases, centralized industrial packaging waste disposal industrial parks. The equipment can operate independently as the main primary shredding host or be connected in multiple units to form a network, matching belt conveying, magnetic separation and air separation equipment to build a fully automatic sorting and recycling production line.
