[0002] High-wear-resistant powder coatings are coatings with extremely high wear resistance, mainly used for surface protection that needs to withstand high-intensity wear. The powder coating crushing process requires a micro-pulverizer, which is an outward-facing high-speed pulverizer where materials enter the crushing chamber for crushing.

[0003] A powder coating pulverizer, according to Chinese patent publication number CN208960043U, includes an upper base plate, a lower base plate, and a support column. A first bearing is fixedly mounted on the upper base plate, and a pulverizing cylinder feed end is rotatably connected within the first bearing. A first driven gear is fixedly connected to the upper part of the feed end of the pulverizing cylinder, with two connected first driven gears meshing with each other. The first driven gear at the far end meshes with a first driving gear. A stirring shaft is installed inside the pulverizing cylinder, with pulverizing blades symmetrically arranged on both sides of the stirring shaft. A second bearing is fixedly mounted on the lower base plate, and the lower end of the stirring shaft is rotatably connected within the second bearing. A second driven gear is also fixedly connected to the lower part of the stirring shaft, with adjacent second driven gears meshing with each other. The second driven gear at the far end meshes with a second driving gear, and the first and second driving gears rotate in opposite directions. This powder coating pulverizer of the present invention can greatly improve the pulverizing effect and efficiency.

[0004] However, existing devices still have the following problems: the crushed material needs to be removed for manual screening, but manual screening is inefficient and increases labor time, resulting in low efficiency in crushing high wear-resistant powder coatings. Therefore, a micro-pulverizer for crushing high wear-resistant powder coatings is proposed. Utility Model Content
