Twin‑screw extruders operate under low‑speed, high‑torque and continuous heavy‑duty conditions with complex and harsh working environments. They are subjected to high mixing resistance, frequent material fluctuations and numerous transient shock loads, so ordinary transmission protection components are completely unsuitable. The drawbacks of conventional protection solutions are quite obvious:• Electronic overload protection: Overload is predicted based on current and rotating speed, with a millisecond‑level response delay. When sudden jamming shock occurs, power‑off shutdown cannot be triggered in time and equipment damage has already taken place.• Traditional shear‑pin protection: The shear pin fractures immediately upon overload. Every breakdown requires downtime for pin replacement and alignment adjustment, which is time‑consuming and labor‑intensive and seriously reduces production efficiency.• General‑purpose torque limiter: It features poor torque accuracy and weak fatigue resistance. Unable to adapt to the sustained high‑torque conditions of extruders, it is prone to false disengagement and protection failure.
The torque limiter specially designed for twin‑screw extruders is customized for extruder heavy‑duty, shock‑prone and continuous‑operation scenarios, directly solving all major pain points in the industry.✅ Millisecond Instant Disengagement, Zero‑Residual Torque for Full‑Machine ProtectionUltra‑fast overload response within milliseconds. Once the equipment torque exceeds the preset threshold, power transmission is cut off instantly and residual torque drops to zero, completely blocking the transfer of shock loads. It effectively prevents major failures such as shaft breakage, gear tooth fracture, screw deformation and gearbox damage caused by material jamming or foreign‑object blockage, and fully protects high‑value core components including motors, gear reducers and screw shafts.✅ Precisely‑Controllable Torque, Adaptable to Full‑Range Working‑Condition ProductionAdopting a precision disc‑spring adjustment structure, it achieves torque‑control accuracy of ±3%. The protective torque can be accurately set according to different materials, process formulas and extrusion speeds. It avoids frequent false shutdowns caused by excessively low torque to guarantee continuous production, while preventing protection failure resulting from over‑high torque. It is perfectly applicable to various twin‑screw extrusion processes, such as compounding granulation, filling modification, toughening modification and fiber drawing.✅ Vibration & Noise Reduction for Stable Extrusion ConditionsBuilt‑in high‑elasticity vibration‑absorbing buffer elements effectively absorb high‑frequency vibration and transient shocks during extruder operation, compensate for installation deviation and reduce jitter of the transmission system. It not only lowers operating noise and component wear, but also delivers more uniform material extrusion, stabilizes product quality and indirectly improves the finished‑product qualification rate.✅ Optimized for High‑Torque Heavy‑Duty Service with Excellent DurabilityOptimized for the harsh low‑speed, high‑torque, 24‑hour continuous‑running working conditions of twin‑screw extruders. Made of high‑strength materials, it delivers outstanding fatigue resistance, shock resistance and wear resistance. It can steadily bear long‑term high‑load transmission and eliminate protection failure and component aging after prolonged operation, with a service life far longer than that of general‑purpose products.• Equipment locking‑up and transmission fracture caused by material agglomeration and unexpected jamming
• Instant high‑torque shock and equipment damage triggered by mixed‑in metal foreign objects
• Frequent overload alarms and shutdowns resulting from human‑operation errors or unstable feeding
• Severe wear and sharp service‑life reduction of transmission parts under long‑term heavy‑load operation
• Long breakdown downtime, high maintenance costs and insufficient production capacity to satisfy order demandsFor extrusion‑processing enterprises, installing a dedicated torque limiter is not an added cost, but a highly cost‑effective risk‑control investment for equipment. With a small investment, you can avoid maintenance expenses amounting to tens of thousands, cut unproductive downtime losses and firmly safeguard the production capacity and profit of your production line.
The core loss of an extruder never comes from wear during normal production, but irreversible damage caused by repeated sudden overloads. Rather than spending money on repairs and stopping production to contain losses after faults, it is better to carry out preventive protection in advance. A dedicated torque limiter builds a solid safety barrier for your equipment. With precise protection, stable durability, time‑saving & cost‑cutting performance and strong adaptability, it enables every extruder to run at full load, in stable condition and with an extended service life.
