Zirconium oxide beads have good wear resistance and are durable. In the process of use, if they are not used frequently, it is OK to use them for 2-3 years. After the zirconium beads wear to a certain extent, the production capacity will drop, and the grinding fineness will slowly fail to reach the standard. At this time, it is necessary to consider changing the beads. Many customers will struggle whether to replace all of them or just part of them.
Generally, when the equipment is purchased, zirconia beads are supplied with the equipment. The customer just uses them. He does not know that there are many types of zirconia beads. When he finally needs to replace them, he does not know how big the original zirconia beads are, and how many beads the equipment needs to be filled with. In particular, it is not clear whether the beads are pure zirconium or zirconium aluminum. In this case, it is recommended that all beads be replaced because zirconium beads with different contents are mixed together, There will be grinding of beads, resulting in breakage of beads with low hardness.
If you don’t know the size of the bead, you can use a ruler to measure it. Select some large beads and some small ones, and then you can judge the size of the original bead. The zirconia beads can be replaced with new one at a time, which can improve the productivity and the new zirconia bead has better strength and longer service life.
So replacing all the beads is the best choice.
