I. Principle and characteristics of powder recovery system in powder mill


Powder recovery system in powder mill is a kind of common powder recovery equipment. Its principle is to use the wind to suck the powder scattered in the air into the recovery system, and separate the powder through the screen, centrifugal and other ways to realize the recovery and reuse of powder. The main features of powder recovery system in powder workshop are as follows:


1. High efficiency: 

Powder recovery system in powder workshop can efficiently recover the powder scattered in the air, which greatly improves the utilization rate of powder and production efficiency.


2. High accuracy: 

Powder recovery system in powder workshop can precisely control the quantity and quality of recovered powder, which ensures the consistency and stability of the coating.

3. Good environmental protection: 

Powder recovery system in powder workshop can effectively reduce dust pollution, reduce the impact on the environment and meet the environmental protection requirements of modern industry.


4. Low maintenance cost: 

Powder recovery system in powder workshop has simple structure, easy operation and low maintenance cost, which reduces the operation cost of enterprises.

II. Factors affecting the efficiency of powder recovery in powder workshop



1. Powder particle size and density: 

the smaller the powder particles, the easier it is to scatter in the air, which has a certain impact on the recovery efficiency. And the greater the density of the powder, the easier it is to be inhaled by the recovery system.

Structure and design of the recovery system: The structure and design of the recovery system also have a great impact on the recovery efficiency. Reasonable structure and design can improve the recovery efficiency and reduce the waste of powder.


2. Ambient temperature and humidity: 

ambient temperature and humidity are also factors that affect the recovery efficiency. In higher temperatures, the powder is easily blown away by the wind, while in higher humidity, the powder tends to adhere to the surface of the equipment, affecting the recovery efficiency.


3. Spraying parameters: 

spraying parameters are also an important factor affecting the recovery efficiency. If the spraying volume is too large or spraying speed is too fast, the powder is easily scattered in the air, affecting the recovery efficiency.


4. The operating status of the recovery system: 

the operating status of the recovery system will also affect the recovery efficiency. If the equipment fails or does not work properly, the recovery efficiency will be affected.


5. The nature of the powder material: 

different kinds of powder materials have different physical and chemical properties, these properties will also affect the recovery efficiency. For example, some materials are easily adsorbed on the surface of the equipment and are difficult to recover.


6. Operating skills and experience: 

Operating skills and experience also have a great impact on the recovery efficiency. Reasonable operating skills and experience can improve the recovery efficiency and reduce the waste of powder.

III. Conclusion

In the powder coating process, the powder recovery system in the powder workshop is a very important link that can effectively improve powder utilization and reduce production costs. Reasonable design and operation can improve the recovery efficiency, reduce the waste of powder and ensure the quality and stability of the coating. Therefore, enterprises should pay attention to the maintenance and management of the powder recovery system in the powder workshop, and continuously optimize the structure and operation skills of the recovery system to improve the production efficiency and economic benefits.
