SXTA99 is produced from high-purity Al₂O₃ by pressing followed by molding and high-temperature sintering. A special recipe and strict quality control allow us to achieve:
Maximum hardness and density
Minimal wear
High roundness and uniformity of particles
Each batch undergoes strict control to ensure compliance with standards, which guarantees stable parameters for industrial processes.
Health: low risk, not toxic
Flammability: does not ignite
Chemical reactivity: resistant to aggressive environments
Spill measures: collect the balls, use safety glasses and a mask
Storage: in a dry room, follow the rules for handling heavy materials
Using SXTA99 reduces the frequency of changing grinding balls, minimizes equipment wear and increases mill productivity. High stability of the material allows long grinding cycles without loss of quality. This makes the SXTA99 the optimal solution for industrial plants with high demands on quality and efficiency.
