70% ZTA320 Alumina Ceramic Balls

70% ZTA320 alumina ceramic balls production process includes the following steps: powder making-molding-sintering-polishing-drying-sieving-packaging. The pickaxe ball production process includes the following steps: powder making-molding-sintering-polishing-drying-sieving-packaging.
Molding: The loose powdery raw materials are prepared through mechanical operation into spherical blanks with high volume density, good solidity and uniform size;
Sintering: Place the prepared zirconium bead blank in the kiln and sinter it through three zones of high temperature to make its density and strength meet the process requirements;
Polishing: Put the zirconium beads after sintering into the roller polishing machine, add the corresponding brightener, and grind the zirconium beads to achieve the brightness in this process;
Drying: Place the polished zirconium beads on a dryer to dry;
Screening: Pass the dried zirconium beads through a sorting machine to sort out the zirconium beads with unqualified roundness, thereby ensuring the pass rate of the roundness of the zirconium beads leaving the factory;
Packaging: The zirconium beads that have passed the sorting and pressure test will be size screened. After ensuring that the particle size distribution of the zirconium beads is uniform, they will be packaged.

70% ZTA320 alumina ceramic balls have high strength and toughness at room temperature, good wear resistance, high temperature resistance and corrosion resistance, high stiffness, non-magnetic conductivity, and electrical insulation. When the zirconia ceramic ball is at 600°C, its strength and hardness are almost unchanged, its density is 6.00g/cm3, its thermal expansion rate is close to the thermal expansion rate of metal, and it can be used in conjunction with metal. Suitable for bearings, seals, etc. In our production process, the use of zirconia abrasives can reduce the usage of resin, increase the usage of fillers, increase the fixed content, reduce VOC and reduce costs.
70% ZTA320 alumina ceramic balls are currently widely used in the fields of grinding and dispersion. Grinding is mainly used in sand mills, and dispersion is mainly used in high-speed stirring mills. For example, when we use a sand mill to grind ink, we need to use zirconia abrasives. The inks here mostly refer to gravure inks with relatively low viscosity. This kind of ink has very high requirements for fineness. This is where zirconia beads come into play because they have high density and good toughness, and can be used with high-speed horizontal printing. The use of a sand mill can grind materials to the nanometer level, so that the ink produced in this way is more effective. In some industries with high requirements for inks, it is clearly stated that the inks used need to reach the nanometer level. The editor here would like to remind everyone that not all sand mills can use this product. For example, pure zirconia beads are not recommended for vertical sand mills. Unless the density of the raw materials you grind is very high, otherwise it will be very difficult. It is easy for the abrasive to sink to the bottom, which will seriously affect the grinding efficiency.
Let's take a look at the application of 70% ZTA320 alumina ceramic balls in dispersion. This aspect is mainly used in vertical mixing mills to quickly disperse mixed materials. The rapid dispersion and mixing of materials is a technical difficulty, and the combination of stirring mill and zirconia abrasive can solve this problem very well. Through the force of the stirring blade, high-speed and disorderly movement is made in the material, which greatly improves the mixing efficiency. , which is dozens of times more efficient than ordinary mixers, in which the role of zirconia abrasives plays an important role.
