With the rapid development of polymer materials today, polymer filling, blending, modification and other processes have become important directions for new material research and development. In order to meet the laboratory's small batch, multi-formula, high-precision processing needs, the split small precision twin-screw extrusion granulation line has become the preferred equipment for universities, scientific research institutions and corporate R&D centers to conduct material experiments and process explorations due to its compact structure, flexible operation and high mixing efficiency.

The split small precision twin-screw extrusion granulation line consists of a split small precision twin-screw extruder, a screen changer, a granulation mold, a cooling water tank, an air drying device, a pelletizer and other modules, forming a complete experimental system. The entire production line is scientifically designed and reasonably laid out, and can achieve continuous operation from raw material melting to finished granule output. It is suitable for the processing needs of a variety of polymer materials, especially for small and pilot applications in the new material research and development stage.

Among them, the extrusion mixing system adopts a split integral barrel structure, which makes the equipment easy to disassemble, clean and maintain after the experiment, effectively avoiding cross-contamination between different materials, and improving the adaptability and flexibility of the equipment. This is especially important for laboratories that frequently change formulas or handle high value-added materials.

The core component of the equipment is a parallel meshing co-directional twin-screw structure with high matching accuracy and small gap control ability. By reasonably combining different types of threaded elements, efficient mixing, plasticization and dispersion of materials with various characteristics (such as heat-sensitive, high-viscosity, and filled types) can be achieved. This highly adjustable screw configuration makes the equipment more versatile and adaptable, and can meet the processing needs of different material systems. It is an ideal tool for studying material rheological behavior, compatibility, dispersibility and other properties.

In addition, the modules of the production line are smoothly connected and fully functional. The screen changer can effectively remove impurities in the melt and improve the purity of the product; the granulation mold can be replaced with different apertures as needed to achieve diversified particle output; the cooling water tank is used in conjunction with the air drying device to ensure that the particles are quickly cooled and shaped and the surface moisture is removed; finally, the pelletizer completes efficient cutting to obtain regular, dry, and easy-to-test granule products. The entire process has a high degree of automation, simple operation, and good repeatability of experimental results, which helps researchers to accurately grasp the relationship between process parameters and material properties.

The split small precision twin-screw extrusion granulation line equipment is particularly suitable for experimental research on filling modification, blending alloying, toughening and strengthening of polymer materials, and is widely used in plastics, rubber, biodegradable materials, composite materials and other fields. Due to its moderate output, low energy consumption and small footprint, it is very suitable for use in laboratory environments, which not only saves raw materials, but also facilitates rapid verification of formula effects, greatly improving R&D efficiency.

Not only that, the split small precision twin-screw extrusion granulation line also has outstanding performance in safety and intelligence. The equipment is equipped with multiple safety mechanisms such as overload protection and abnormal temperature alarm to ensure stable and reliable operation. Some models also support intelligent control systems to achieve real-time monitoring and adjustment of key parameters such as temperature, speed, and pressure, and improve the accuracy and traceability of experimental data.

In summary, the split small precision twin-screw extrusion granulation line has become an indispensable and important equipment in the research and development of new materials with its advantages such as flexible structure, uniform mixing, convenient operation, and complete functions. It not only meets the laboratory's needs for diversified and refined processing, but also provides scientific researchers with an efficient and stable technical platform. Choosing such a set of equipment is not only a guarantee of experimental quality, but also an effective improvement of innovative research and development efficiency. Whether in university teaching, scientific research units or enterprise technology centers, it will become an important boost to promote the advancement of materials science.
