【 摘 要 】

Using the ball mill to grind the recycled fine powder at different times to study the effect of physical excitation on the properties of the recycled fine powder. The results show that the use of physical excitation can make the particle size of the recycled fine powder continuously decrease, and the particle size distribution tends to be reasonable. With the prolongation of the grinding time, the particle content of
