As the fineness requirements of materials become higher and higher, the use of sand mills is becoming more and more common, and there are more grinding media on the market, and zirconia beads are among the leaders. How to choose one that is more suitable for you Grinding media for production processes and conditions are of particular concern to grinder manufacturers. The following editors make a simple analysis on the following aspects:
1. Pay attention to the density of the grinding medium
Under normal circumstances, the larger the specific gravity of the zirconia beads is, the higher the grinding efficiency is, and the contact parts of the sand mill (inner cylinder, dispersion plate, etc.) are relatively worn. Therefore, the viscosity and flow of the slurry are closely related. Healthy. Low-density grinding beads are suitable for low-viscosity slurry, and high-density grinding beads are suitable for high-viscosity slurry. When choosing Dongguan zirconia beads, we should pay attention to cooperate with the slurry, so that we can show good grinding performance and protect the machine from damage.
2. Pay attention to the particle size of the grinding medium
The size of the zirconia beads determines the number of contact points between the grinding beads and the material. The more contact points the beads with a smaller particle size have in the same volume, the higher the theoretical grinding efficiency. In the case of materials, the impulse of the small beads cannot reach the energy of sufficient grinding and dispersion. At this time, beads with a larger particle size should be used.
3. Pay attention to the hardness of the grinding medium
Mohs and Vickers are commonly used indicators. The higher the hardness of zirconia beads, the lower the wear rate of the beads does not mean. From the point of view of the wear of the grinding beads on the contact parts of the sand mill (dispersion disc, rod pin, inner cylinder, etc.) during use, the wear of the contact parts of the grinding beads with greater hardness is greater, but the amount of beads can be adjusted by adjusting , Slurry viscosity, flow rate and other parameters to achieve a better optimization point.
The above are some of the important considerations when purchasing zirconia beads, and the manufacturers of zirconia beads will also make recommendations based on the different needs of consumers when selling products, and bring high-quality customer service to consumers. More reliable and reliable experience, so consumers only need to choose a reliable zirconia bead manufacturer to ensure that they have no worry about buying.
