GUOMAO SZL Twin-Screw Extruder Dedicated Reducer
The GUOMAO SZL Twin-Screw Extruder Dedicated Reducer is a professional vertical integrated conical twin-screw transmission gearbox specially developed for plastic and rubber conical twin-screw extrusion equipment. Adopting optimized hard-tooth helical gear transmission and integrated synchronous double-shaft output structure, paired with high-strength alloy steel precision grinding and circulating water cooling system, this series features fixed precise speed ratio, synchronous double-shaft stable output, low vibration mute operation, compact integrated structure and long-term continuous extrusion stability. Professionally optimized for the synchronous operation and high-precision mixing requirements of twin-screw extruders, it effectively solves common industry pain points such as asynchronous screw operation, unstable mixing quality, high operating noise and easy temperature rise of traditional twin-screw reducers. With targeted working condition design and reliable industrial durability, it has become the core dedicated supporting transmission equipment for plastic modification, mixing and granulation twin-screw production lines.

Speed Ratio: 37–39
Max. Output Torque: 13.13 kN·m
2.1 Exclusive Fixed Speed Ratio for Twin-Screw Synchronous Operation
The SZL series adopts a professional fixed speed ratio range of 37 to 39, which is exclusively customized for the synchronous rotation and equal-speed mixing process requirements of conical twin-screw extruders. The precise single-range speed ratio design realizes zero-error synchronous operation of double output shafts, completely avoiding material mixing unevenness, material jamming and extrusion quality deviation caused by speed difference of the two screws. Matched with a power range of 22kW to 110kW, it fully covers the mainstream medium-power twin-screw extrusion equipment in the market, achieving perfect parameter matching and no power waste for twin-screw mixing and granulation working conditions.
2.2 13.13kN·m Stable Torque & Uniform Synchronous Load Bearing
With a maximum output torque of 13.13kN·m, the SZL dedicated reducer provides stable and balanced torque reserve for twin-screw high-pressure mixing and extrusion. Core gears are made of high-quality alloy steel, processed through strict carburizing, quenching and precision grinding, reaching Grade 6 high precision with high tooth surface hardness and strong wear resistance. The optimized double-shaft balanced meshing structure ensures uniform force distribution of the two output shafts, effectively resisting material mixing resistance and slight impact load during long-term operation. It maintains stable and consistent torque output of double shafts without jitter or attenuation, ensuring uniform material plasticization and stable product quality.
2.3 Integrated Vertical Compact Structure & High Positioning Accuracy
Different from split traditional reducers, the SZL series adopts an integrated vertical all-in-one structure integrating distribution box and main gearbox, with compact overall volume and high structural integration. The integral high-rigidity cast iron housing undergoes secondary stress relief treatment, which effectively eliminates structural internal stress and avoids deformation and displacement under long-term mixing vibration. The precise double-shaft positioning design ensures low runout of the output end, effectively improving the assembly accuracy and operation stability of twin-screw equipment, and saving valuable installation space for extrusion production lines.
2.4 Circulating Water Cooling & Low-Temperature Continuous Operation
Equipped with a built-in professional circulating water cooling system, the SZL series can rapidly and continuously export internal heat generated by 24-hour high-intensity mixing and extrusion operation. It perfectly solves the problems of excessive temperature rise, lubricating oil deterioration and accelerated gear wear of traditional twin-screw reducers under long-cycle working conditions. The low-friction precision meshing structure reduces idle power loss and heat generation, ensuring constant-temperature stable operation of the whole machine and greatly extending the service life of internal components.
2.5 Ultra-Low Vibration & Mute High-Precision Production
Through professional tooth profile correction and meshing clearance fine optimization, the gear meshing process is smooth and accurate without impact and resonance. The whole machine operates with ultra-low vibration and low noise during full-load continuous operation, fully meeting the mute and high-precision production standards of modern plastic modification, new material mixing and clean workshop environments. It effectively avoids equipment vibration affecting material mixing uniformity and product surface finish.
2.6 High Sealing Performance & Low Comprehensive Maintenance Cost
Adopting upgraded multi-layer combined sealing structure, the SZL series has excellent oil leakage resistance, dust-proof and high-temperature resistance, adapting to long-term dusty and high-temperature working environments of plastic processing workshops. The standardized integrated modular structure has fewer vulnerable parts, with simple and convenient daily lubrication and maintenance procedures. It supports long-term uninterrupted industrial production, effectively reducing equipment downtime and later comprehensive operation and maintenance costs, with outstanding long-term cost performance.
