Shearing and mixing effects of large capacity high filler granulation production line: improving the production efficiency and quality of high filler masterbatch

1. Working principle of large capacity high filler granulation production line
The large capacity high filler granulation production line consists of two parallel and intermeshing screws, which rotate at high speed in the barrel of the machine to form strong shearing force and flow force to fully mix and plasticize the raw materials. When producing filling masterbatch, the raw materials usually include plastic carriers and inorganic fillers. After pre-mixing, these raw materials are further mixed and processed by large capacity high filler granulation production line.

2. The important role of shearing force in mixing
The shearing force of large capacity high filler granulation production line is one of its core advantages. Under the high-speed rotation of the twin screws, the material is subjected to severe shearing, which can quickly disperse the larger particles of inorganic filler into the plastic matrix. For the production of filling masterbatch, especially for products with high filling amount, shearing force plays a vital role. The dispersing effect of inorganic fillers such as calcium carbonate and talcum powder directly determines the quality and performance of masterbatch. Good dispersion can improve the mechanical properties, heat resistance and surface smoothness of plastic products.

3. The effect of mixing on the quality of filling masterbatch
In addition to shear force, the mixing effect of twin screws cannot be ignored. When the material passes through the screw, the confined space between the screw and the barrel wall makes the material constantly change direction in the spiral motion trajectory, which promotes the all-round contact and mixing of the material. This strong mixing effect helps to achieve uniform dispersion of each component and avoid excessive concentration or uneven distribution of certain components.

Especially in large-capacity and high-filling production lines, the uniformity of the material directly affects the production stability of the filling masterbatch and the consistency of the product. Good mixing effect not only improves the physical properties of the masterbatch, but also optimizes subsequent processing technology, such as injection molding, extrusion, etc. Therefore, the mixing effect of the twin screw has an important impact on production efficiency, quality control and the performance of the final product.

4. Improve the dispersion and plasticization effect of fillers
The shear force and mixing effect of the twin screw work together to help improve the dispersion and plasticization effect of the filler. In the production of filling masterbatch, inorganic fillers have poor affinity with plastic carriers, which easily leads to uneven dispersion of fillers, resulting in unstable product quality. The twin screw can effectively control the dispersion effect of fillers through precise thread design and appropriate temperature control system, avoiding filler agglomeration and unevenness.

In addition, the high shear force of the twin screw also helps to improve the plasticization effect of the material. Both the melting of the plastic carrier and the dispersion of the filler can be completed in a short time, thereby improving production efficiency. For large-capacity high-filler masterbatch production lines, this efficient mixing and plasticization can maintain stable product quality in large-scale production and meet the needs of mass production.

5. Advantages and application prospects of large capacity high filler granulation production line
The application of large capacity high filler granulation production line in large capacity high filling production line can not only improve the efficiency of mixing and dispersion, but also improve the mechanical properties, thermal properties and processing properties of the product. With the increasing market demand for high-performance and low-cost plastic products, large capacity high filler granulation production line shows great potential in the production of filling masterbatch. Its efficient shearing and mixing effects enable it to ensure high filling uniformity during the production process, adapt to various raw material combinations, and are widely used in plastic pipes, films, injection molded parts and other fields.
