Solution

The recycling and granulation of materials such as PE and PP is a process with extremely high environmental and economic value. It can recycle and reuse discarded plastic materials, thereby reducing pollution to the environment, while also saving the use of raw materials and reducing production costs. In the process of recycling extrusion granulation, the problem of impurity filtration needs to be solved, which is an important link to ensure product quality.

In order to solve the problem of impurity filtration, a variety of double plunger screen changers (round screen, long round screen and full wrap screen) and plate screen changers can be used. These screen changers have excellent filtering performance and efficient cleaning ability, which can effectively filter out impurities and ensure the quality and stability of the product.

Among them, the double plunger screen changer is a commonly used filtering equipment. It adopts a double plunger structure. Through the synergistic effect of the upper and lower plungers, the filter screen can be quickly replaced and cleaned. Round screen, long round screen and full wrap screen are three commonly used filter screens. They all have excellent filtering performance and efficient cleaning ability, which can effectively filter out impurities and ensure the quality and stability of the product.

Plate screen changer is another commonly used filtering equipment. It adopts a multi-layer plate structure and realizes the filtering effect through the gap between the plates. Plate screen changer has the advantages of simple structure, convenient maintenance, high filtering efficiency, etc., and is suitable for filtering a variety of materials.

In practical applications, choosing a suitable screen changer requires considering many factors, such as the type of material, the requirements of the production process, the requirements of filtering efficiency, etc. At the same time, it is also necessary to pay attention to the maintenance and care of the screen changer, and regularly clean and replace the filter screen to ensure its normal operation and filtering effect.

In short, the recycling and granulation of materials such as PE and PP is a process with extremely high environmental protection and economic value, and solving the problem of impurity filtration is an important link to ensure product quality. Choosing a suitable screen changer can effectively solve the problem of impurity filtration, improve the quality and stability of the product, and at the same time reduce production costs and achieve the goal of sustainable development.
