Quality Traceability Alumina Grinding Ball
Product Introduction

High hardness alumina grinding balls are essential grinding consumables for the ceramic, mineral, and cement industries. Specially designed for hard materials, they solve the problems of low efficiency and rapid wear associated with ordinary grinding balls when processing quartz sand and corundum raw materials.

Field tests show a 20% increase in production efficiency and 15% reduction in finished product defects when grinding ceramic glazes, ensuring stable production and superior product quality.
Key Features
  • Exceptional hardness: Mohs hardness of 9+ (second only to diamond)
  • High-temperature sintering technology creates smooth, dense surfaces (Ra0.8μm roughness)
  • Proven durability: Only 0.3% monthly wear during quartz sand grinding (vs. 1.5% for standard balls)
  • Minimal debris generation (≤0.01%) prevents material contamination
Performance Benefits
  • Ceramic glaze grinding: Achieves ≤0.1% residue at 325 mesh, reduces grinding time by 1.5 hours
  • Mineral processing: Increases corundum fine powder production by 25% with uniform particle size
  • Adaptable to various high-hardness material grinding applications
