GUOMAO SZ Series Conical Twin-Screw Extruder Reducer
The GUOMAO SZ Series Conical Twin-Screw Extruder Reducer is a high-power, heavy-duty professional transmission gearbox independently developed for full-range conical twin-screw extrusion equipment. Adopting high-precision hardened helical gear transmission technology, optimized synchronous dual-shaft output structure and integrated high-rigidity housing design, this series features ultra-wide power and speed ratio coverage, 42kN·m super-large torque output, excellent synchronous transmission accuracy, strong overload resistance and long-term stable heavy-load operation. It is comprehensively upgraded on the basis of traditional twin-screw reducers, perfectly adapting to high-pressure extrusion, uniform mixing and long-cycle continuous production characteristics of conical twin-screw units. It effectively solves common industry problems such as insufficient torque, narrow matching range, asynchronous screw operation and poor heavy-load stability of conventional reducers. With ultra-strong universal matching performance and reliable industrial durability, it is a universal core supporting transmission product for small, medium and large conical twin-screw extrusion production lines.
Power (kW): 5.5–200kW
Speed Ratio: 8–35
Max. Output Torque: 42 kN·m
2.1 Ultra-Wide Parameter Coverage & Full-Range Universal Matching
The SZ series covers a full power range of 5.5kW to 200kW and a flexible speed ratio range of 8 to 35, far exceeding the parameter coverage of conventional twin-screw reducers. It can freely adapt to low-speed high-torque heavy extrusion and medium-high speed efficient mixing working conditions, fully matching small, medium and large conical twin-screw extruders on the market. The diversified speed ratio combination avoids equipment modification and model selection limitations, realizing one machine compatible with multiple extrusion processes such as plastic mixing, modification, granulation and profile molding, with extremely high versatility.
2.2 42kN·m Super High Torque & Outstanding Overload Resistance
With a maximum output torque up to 42kN·m, the SZ series has industry-leading heavy-load bearing capacity, providing sufficient and stable torque reserve for high-pressure twin-screw extrusion. Core gears are forged from high-strength alloy steel, processed through carburizing, quenching and precision tooth grinding, with high surface hardness and strong wear resistance. The optimized dual-shaft synchronous meshing structure realizes uniform load distribution, which can effectively resist instantaneous material impact, frequent load fluctuation and long-term full-load alternating load. It maintains stable non-attenuating torque output of double screws, ensuring consistent extrusion pressure and uniform material plasticization effect.
2.3 High-Precision Synchronous Transmission & Stable Extrusion Quality
Aiming at the core demand of synchronous operation of conical twin-screws, the SZ series adopts professional gear pairing calibration and backlash optimization design. It realizes zero-deviation synchronous operation of double output shafts, completely avoiding material accumulation, uneven mixing, material jamming and product dimensional errors caused by speed difference and transmission hysteresis. The high-precision assembly process controls the output shaft runout within a low range, effectively improving the surface finish and dimensional stability of extruded products, meeting high-standard production requirements of high-end polymer materials.
2.4 Integrated High-Rigidity Structure & Strong Vibration Resistance
The whole machine adopts an integrated thickened cast iron housing with complete stress relief treatment, which thoroughly eliminates internal structural stress and effectively resists deformation and displacement caused by long-term high-frequency vibration and heavy extrusion pressure. The optimized internal force-bearing structure improves overall rigidity and stability, avoiding resonance during full-speed operation. Compared with split structural reducers, it has higher assembly precision and structural durability, greatly reducing equipment failure rate.
2.5 Low Heat Generation & 24-Hour Continuous Heavy-Duty Operation
Equipped with an optimized circulating lubrication and efficient heat dissipation system, the SZ series can quickly export internal heat generated by long-term full-load operation. The low-friction precision meshing structure reduces power loss and heat accumulation, effectively solving the problems of excessive temperature rise, oil aging and accelerated gear wear of traditional twin-screw reducers under long-cycle working conditions. It supports 24-hour uninterrupted high-intensity extrusion production, with excellent anti-fatigue performance and stable long-term operation.
2.6 Excellent Sealing & Harsh Environment Adaptability
Adopting upgraded multi-layer composite sealing structure, the reducer has superior oil leakage prevention, dust-proof and high-temperature resistance. It can operate stably for a long time in high-temperature, dusty and high-humidity plastic processing workshops, adapting to complex and harsh industrial working environments. The wear-resistant and anti-corrosion core components effectively extend the overall service life of the equipment.
2.7 Flexible Installation & Low Comprehensive Operating Cost
The SZ series supports multiple installation methods with standard universal mounting interfaces, which is highly compatible with all mainstream conical twin-screw extruders in the market. It is convenient for on-site assembly, disassembly and old equipment replacement without complex structural modification. The standardized modular design reduces vulnerable parts, simplifies daily maintenance and lubrication procedures, effectively reducing equipment downtime and long-term operation and maintenance costs, with outstanding comprehensive cost performance.
