AI Technical Summary
In existing air-grinding micro-aluminum powder devices, aluminum powder particles enter the classifying drum and are directly fed into the next device by airflow, resulting in fewer grinding collisions and low grinding efficiency.
An air-grinding device for fine aluminum powder was designed, comprising a multi-layer cylindrical structure and a drive motor system. The drive motor drives a rotating rod to rotate, which in turn drives a disc and a cylinder to rotate, causing the aluminum powder particles to collide and grind multiple times between the cylinders, thereby improving grinding uniformity and efficiency.
Through multiple collisions, the grinding uniformity and grinding efficiency of aluminum powder particles are significantly improved, meeting the particle size and gloss requirements of high-end coatings and inks for fine aluminum powder.
