What are the grinding beads used in the sander?
The commonly used grinding media in sanding machines (such as vertical sanding machines, horizontal sanding machines, rod pin machines, dual-power nano sanding machines, disk sanding machines) are: glass beads, steel balls, zirconium silicate beads, zirconia beads, pure zirconia, etc., there are many kinds and sizes.
How to choose the suitable grinding medium?
Zirconia beads are made of micron grade and sub-nano grade raw materials, using advanced technology, and the technical indicators and performance have reached the international advanced level, generally used in horizontal sand mills and nano sand mills. It is mainly used in the ultra-fine grinding and dispersion of materials requiring "zero pollution" and high viscosity and high hardness, such as: electronic ceramics, magnetic materials, zirconia, silicon oxide, zirconium silicate, titanium dioxide, medicine and food, pigments, dyes, inks, special chemical industry.
The internal microcrystal structure of zirconium silicate beads is uniform and fine, compared with zirconium oxide beads, the density of zirconium silicate beads is small (zirconium silicate bead density 4, zirconium oxide bead density 6), the grinding efficiency is not as good as zirconium oxide beads, because of its toughness is not good zirconium oxide beads, high-speed grinding is easy to break the beads, so zirconium silicate beads are mainly used in the vertical sand mill with low speed.
Take glass beads as an example, its density varies with the type of metal in the glass composition, but the selection can not only consider the strength and density of the glass, because the grinding material will be contaminated and affect the quality, but also consider the glass composition.
The grinding medium is one of the important factors affecting the efficiency of the sand mill, so it must be paid attention to when using.
