Twin screw granulator is a commonly used granulation equipment, and its process flow includes the following steps:
1、 Raw material processing
Firstly, the raw materials need to be processed, including screening, cleaning, drying, etc. These steps can be adjusted according to different raw materials to ensure the quality and suitability of the materials.
2、 Mixing
Mix the processed raw materials to achieve a uniform material composition. The purpose of mixing is to ensure consistency and stability in granulation.
3、 Transportation
Transport the mixed material to the feed port of the twin-screw granulator. The conveying method can be adjusted according to different production requirements, and common conveying methods include spiral conveying, pneumatic conveying, etc.
4、 Squeeze
The main working principle of a twin-screw granulator is to compress materials into granules through the rotation and compression of the twin-screw. During the extrusion process, it is necessary to adjust the parameters such as rotational speed, temperature, and pressure of the twin-screw according to different materials and process requirements.
5、 Cutting
After extrusion, the material forms particles of a certain size that need to be cut. The cutting method can be adjusted according to different process requirements, and common cutting methods include rotary cutting, vibration cutting, etc.
6、 Drying
After cutting, the particles need to be dried to remove excess moisture and adjust the moisture content of the particles. The drying method can be adjusted according to different materials and process requirements. Common drying methods include natural drying, fluidized bed drying, etc.
7、 Screening
After drying, the particles need to be screened to remove unqualified particles and adjust their size. The screening method can be adjusted according to different process requirements, and common screening methods include vibration screening, rotary screening, etc.
