Yantai Jiecheng Powder Equipment Co., Ltd. researched and developed the patented equipment particle size optimization mill set. Through innovative optimization of grinding and grading technology, it solved the requirement of continuous growth of powder coating quality in the current powder coating production process, and has reached the level of advanced process equipment for powder coating production in the world.

In order to produce high-quality powder coating products, the pieces crushed by extrusion cooling must be graded by professional grinding and sorting equipment. Based on ACM EC easy-to-clean mill group, Yantai Jiecheng Powder Equipment Co., Ltd. developed the technology of particle size optimization and grading, which can effectively separate and adjust the content of fine powder less than 10um in the process of powder coating production, and produce high-quality powder coating products with very high particle size concentration, referred to as Jiecheng particle size optimization system for short. This equipment system of particle size optimization grinding technology provides the equipment foundation for high-quality Bo Tu and high-quality special coating in powder coating technology, which can meet the requirements of powder coating for special products and is the production technology system of the highest-quality powder coating.

　　Particle size is an important attribute of powder coatings, and the concentration of particle size directly determines the quality and performance of powder coatings. In view of the strict requirements of high-quality powder coatings on particle size concentration and the properties of powder coatings themselves, Jiecheng particle size optimization system has the following characteristics:

1. Have the ability to produce at least superfine special powder coatings;

2. Excellent particle size distribution and high concentration of particle size; Accurate and adjustable cutting precision;

3. Compact and space-saving design;

4. Easy to switch production mode; Easy to clean and maintain, especially suitable for frequent product replacement;

5. It can be combined with crushing equipment to form an online or offline production system;

At present, there is no problem in grinding powder coating into fine powder, but the problem is how to reduce the powder below 10um as much as possible to obtain ideal powder coating products. The Jiecheng particle size optimization system has well solved the problems of more fine powder below 10um, rising material temperature, storability and concentrated particle size in the process of high-efficiency grinding, and provided preconditions for obtaining ideal quality powder coating.

Jiecheng particle size optimization system can provide necessary process equipment for the production of the best quality powder coatings, and design humanized/easy cleaning and maintenance components and systems.

　The concentration degree of powder particle size is a way to express the concentration degree of powder particle size intuitively.

The formula is as follows:

Particle size concentration of powder coating C=2×D50/(D90-D10)

The larger the concentration value, the more concentrated the particle size of powder coating. High concentration of powder coatings is an important feature of high-quality powder coatings.

The concentration degree of powder coatings has been applied in the technical management system of large and medium-sized powder coatings production, and has become an important part of big data of powder coatings production enterprises.
