Twin screw extrusion granulator
1. The mutual meshing and rotational motion between the twin screws can produce a strong shearing effect, so that the material is fully mixed in the barrel.
2. Various additives, fillers, etc. can be evenly dispersed in the base material. Ensure that the color of the granulated product is uniform.
3. It has the characteristics of positive displacement conveying, which can stably convey the material from the feed port to the discharge port. Ensure the continuity and stability of the production process.
4. During the rotation of the twin screw, the material is subjected to strong extrusion, shearing and friction between the screw and the barrel, which can quickly heat up and reach a good plasticized state
5. By adjusting the screw speed, temperature, pressure and other parameters, it can easily adapt to the granulation needs and production process requirements of different materials.
High-precision temperature sensors and intelligent temperature control instruments are used to accurately control the temperature of each heating section of the barrel, and the temperature control accuracy can reach within ±1℃.
The motor speed is adjusted by a frequency converter or other speed regulating device to achieve precise control of the screw speed. The speed control accuracy is high and can meet the requirements of different materials and processes.

Install a pressure sensor at the barrel or die head to monitor the extrusion pressure of the material in real time, and automatically adjust parameters such as screw speed and feed amount through the control system to ensure the stability of the extrusion pressure.
Equipped with a PLC control system, it can realize automatic operation of the equipment, such as automatic feeding, automatic temperature rise, automatic alarm, etc. It can also perform parameter setting, operation status monitoring and fault diagnosis through the human-machine interface (HMI). The operation is simple and convenient, which improves production efficiency and management level.
