PET extrusion line uses automatic screen changer to reduce recycling costs

In the plastic extrusion production process, the plastic melt will produce some decomposition products after a long time of plasticization, and the raw material itself also contains some impurities. The presence of these impurities not only affects product quality, but also affects the continuity and stability of production. The screen changer is arranged between the screw head and the extruder head, and is used to filter out impurities and foreign matter in the plastic melt to obtain a pure melt. The recycling of plastic raw materials, especially those used in food and beverage packaging, such as PET, which requires a large amount of consumption, will not only benefit the ecological environment, but more importantly, will have a huge economic effect. As a result, many new technologies and processes on how to clean and recycle waste plastics have been born, such as mechanical filtration processes (filtering solid particles out of the melt).

mesh belt screenchanger

With the rise in the price of plastic raw materials, in order to reduce production costs and increase profits, extrusion manufacturers have artificially increased the proportion of recycled materials used. The proportion of recycled materials in some agricultural plastic products reaches 80% to 90%. Screen changer is one of the important factors affecting the quality of plastic recycled materials. The large-scale use of recycled materials has greatly promoted the development of screen changers, brought a broad market to the application of screen changers, and put forward new requirements for screen changers. In order to meet the requirements of the process and greatly reduce the production cost of recycling, Zhengzhou Batte specially designed the ZB-ACB mesh belt type automatic screen changer.

automatic hydraulic screen changer

This screen changer is a true automatic screen changer, using melt pressure or time to control the screen changer action. The distance and speed of filter movement can be freely set. When the pressure or time reaches the set value, the filter screen automatically moves evenly, and the impurities are brought out of the screen changer with the filter screen. After setting, the screen changer runs completely automatically, without manual operation, the mesh belt moves smoothly, the distance is small, and the material pressure and material flow do not fluctuate, which truly realizes constant pressure production. The mesh belt type screen changer adopts water-cooled seal, no leakage, no wear, heating and cooling are automatically controlled by the control system, and the mesh is flexible. The product is not deformed in the process of changing the screen, and the quality is stable. It has the characteristics of no waste, waste generation, and low consumption of raw materials. It is widely used in the production of high-quality, long-run or short-run products such as granulation, cast film, sheet, plate, optical fiber, and various wire drawing. It is especially suitable for the production of high-precision products with strict requirements on material pressure fluctuations.
