What is the grinding effect of narrow particle size distribution of zirconia beads

zirconia ball

Zirconia beads in the screening process, there will be size differences, such as 0.1-0.15, 0.2-0.25, or the particle size is larger, in 1.2-1.4mm, etc., if the size of the zirconia beads are controlled by the particle size is uniform, narrower, the grinding effect will be better? What happens if the particle size distribution is large?

The more uniform the size of zirconia grinding beads, the energy produced by each size of beads will be basically similar, and the self-grinding wear is smaller during the grinding process, at this time, if the material is also uniform in size, the grinding effect is very good.

However, in the grinding material, if there are large particles and small particles, at this time, if the bead size is uniform, the grinding effect of the particle will be poor, and the material grinding will not be uniform enough. However, the diameter of zirconia grinding beads is large, and it is equivalent to the size of beads in the grinding process, so that the contact surface between the grinding medium can be increased, so as to improve the grinding effect and efficiency, and the large grinding beads, its energy is large, can impact the large particles of material finer, so that the material is more uniform, but there will be a large bead grinding small beads, small beads wear will increase, If the quality of the beads is not well controlled in the production process, it will be prone to high wear and even fragmentation.

The narrow particle size distribution of zirconia grinding beads, or the diameter difference is large, need to be selected according to the initial fineness distribution of the material itself, and the fineness to be ground eventually.
