Zirconia Beads | Grinding Media for Sand Mills

Zirconium Beads

In the wet grinding equipment, the role of the sand mill has a very large influence. The common ones are horizontal sand mill, vertical sand mill, basket mill, double cone bar sand mill, and nano mill, Except the vertical sand mill, which uses ordinary 2-3/3-4mm glass beads, and other equipment uses 0.8-2.4mm zirconia beads. There are many types of grinding media used in sand mills for coatings, such as glass beads, corundum ceramic beads, zirconium beads, steel beads, etc., different dispersion media, and also different in water-based or oil-based systems. Grinding efficiency is also different, so coating engineers need to choose suitable grinding media according to grinding equipment.

Application: Paint, Adhesive, Battery, Pharmaceutical industry, Cosmetic

Zirconia beads are our commonly used grinding media. They are made from micron-scale and sub-nanoscale raw materials and advanced technology. Various technical indicators and performance have reached the international advanced level. Mainly used for 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, and zirconium silicate, food, pigments, dyes, inks, special chemicals industry.

As a medium for dispersing and grinding materials, zirconia beads (or zirconia balls) have to solve the problem of transforming the monoclinic system into the tetragonal system in the usual temperature range (0-80 ° C), doping alkaline earth And rare earth oxides are an effective method, so different stabilizers such as yttrium oxide, cerium oxide, magnesium oxide, and calcium oxide have emerged.

Yttria and ceria stabilized zirconia beads are ideal grinding media with high breaking strength and wear resistance. Different stabilizers and zirconia stabilized by different amounts of the same stabilizer have different crystal structures.

The particle size of the grinding media also has a great influence on the dispersion efficiency. In general, the finer the product requires, the smaller the diameter of the grinding media used is, because the smaller the diameter of the media, the greater the probability of shearing between the spheres colliding with each other, and the dispersion efficiency will also be improved. However, if the diameter of the sphere is too small, the kinetic energy of dispersion is too small to disperse the aggregates of the pigment, and the beads are too small, which are easy to block the screen, and the dispersion efficiency is reduced instead.

According to the above situation, the normal equipment uses beads with diameters of 0.5mm, 0.75mm, 1.0mm, etc. according to the diameter of the glass bead grinding media commonly used now. Of course, it depends on the actual situation. For example, the structure and technology of different equipment are different, so the material and size of the supporting grinding media are also different!

FRANLI provides the output of the entire production line supporting the sand mill, and FRANLI’s engineers will also design different supporting solutions according to different industries and material viscosity. We also have a variety of self-developed wet grinding equipment. If you are still looking for For suitable wet grinding equipment suppliers and manufacturers, you can always get in touch with FRANLI.

Guidelines For Sand Mill

The sand mill mainly uses friction, shearing, and collision as effective grinding methods. It is one of the grinding equipment currently applicable to a wide range of material particle sizes and has high grinding efficiency. The energy density per unit volume is large. The control system can complete the continuous grinding and continuous discharging of the slurry, which greatly improves the production efficiency of the sand mill. It has the advantages of high energy density, fine product granularity, small environmental pollution, simple equipment structure, and convenient maintenance.
