Selection of raw materials for alumina porcelain balls: high-quality alpha alumina is used as the core raw material, which is the basic guarantee for creating high-performance alumina ceramic balls.

Alumina porcelain ball wet grinding: Wet grinding alumina using a batch ball mill to achieve the required particle size. This process effectively reduces the generation of dust, improves grinding efficiency, and ensures uniform and delicate powder.

Alumina porcelain ball spray granulation: The ground slurry is mixed with an appropriate amount of binder and granulated through a spray granulation tower. In the tower, the slurry is atomized into tiny droplets through a sprayer, and then dried into a granular powder by a hot air stream. This step significantly improves the fluidity and plasticity of the powder and provides convenience for subsequent molding.

Machine press molding: For large-diameter aluminum oxide balls (≥30mm), machine pressing is usually used to place the powder in a rubber mold and press it through high-pressure pressing. After pressing, a clear mark will be left on the edge of the mold, which is a unique logo of machine pressing balls.

Rolling molding: For alumina balls with smaller diameters (<30mm), rolling molding is more suitable. First make seed balls, then put them into a ball rolling machine. By continuously adding materials and adding water, the seed balls gradually increase. Although the rolling process takes a long time, it can produce wear-resistant and smooth surface alumina balls.

Sintering: The molded alumina ceramic balls are sent into the tunnel kiln for high-temperature firing. With its precise temperature control and efficient production capacity, the tunnel kiln ensures that the alumina balls reach an ideal sintering state during the firing process. During the firing process, key parameters such as sintering temperature, time and atmosphere need to be strictly monitored to ensure that the alumina balls have excellent physical and chemical properties.

Quality inspection: Perform comprehensive quality inspection of fired alumina ceramic balls, including tests in appearance, size, density and hardness, to ensure that the product meets relevant standards and customer needs.

Packaging and storage: Packaging qualified products, marking detailed information (such as specifications, batches, production dates, etc.), and then put them in the warehouse for storage or ship them to customers.
