For example, the curing conditions are relatively harsh, and the curing temperature is generally between 150 and 180 °C. The high curing temperature not only leads to high energy consumption, but also limits the coating of some substrates that cannot withstand high temperatures, such as plastics and wood, greatly affecting the expansion of the application field of powder coatings. Therefore, realizing the low-temperature curing of powder coatings has become one of the development directions in the powder coating industry. Therefore, ultra-low temperature curing powder coatings have emerged. Ultra-low temperature curing powder coatings have the characteristics of low curing temperature and energy saving.

[0003] At present, the sheet grinding devices for preparing ultra-low temperature curing powder coatings in the prior art usually grind the sheets.

There is a problem that sheets cannot be added conveniently and continuously. And when in use, the ground powder is easy to remain in the grinding structure, not easy to be completely discharged, which is easy to affect the reuse, and there is a problem that the powder inside the grinding structure cannot be completely discharged.
