When operating a twin-screw pelletizer, special attention must be given to the main machine to ensure stable performance. Key precautions include maintaining proper current levels, monitoring pressure sensors, and checking lubrication oil pressure. Shutdown operations fall into two categories: normal shutdown and emergency shutdown. Normal shutdown involves gradually stopping feeding, reducing screw speed, and turning off auxiliary equipment. In case of an emergency, the operator should press the emergency stop button and cut off power immediately before troubleshooting the issue.

Prolonging the service life of the twin screw granulator requires attention to some key aspects, including correct operation, regular maintenance and proper care. Here are some suggestions:1. Correct operation 2. Regular maintenance 3. Cleaning and lubrication 4. Temperature control 5. Avoid no-load operation 6. Repair faults promptly 7. Regularly check the electrical system 8. Staff training 9. Check the cooling system regularly 10. Purchase high-quality raw materials

Coupling is an important connecting device between the main motor of the extruder and the gearbox. Currently, nylon rod couplings and safety couplings are commonly used on the market. Nylon rod couplings have a simple mechanical structure and low cost, but the torque is not accurate. They rely entirely on the shear force of the torque greater than that of the nylon rod. When the nylon rod is cut off, it needs to be reattached.

The types of materials that can be made by twin-screw granulators are:1) Glass fiber, the temperature is too low, the resin is semi-melted, and the glass fiber is poorly coated in the latter stage; the temperature is too high, the resin flow is increased, the tempering and shearing action is small,
