How Do Alumina Ceramic Bricks Protect Ball Mills?

Continuous grinding in ball mills and bulk transportation in slurries subject inner equipment shells to heavy mechanical shock and severe abrasive wear. Alumina ceramic bricks are installed as wear-resistant interior linings inside grinding cylinders and pipe walls. Manufactured with high Mohs 9 hardness and exceptional corrosion resistance, these white ceramic liners absorb material impact, effectively preventing steel shell erosion and protecting raw materials from iron contamination.

Matching brick geometries and chemical purity to mill dimensions ensures tight installation and maximum wear resistance. HUAO offers AH-92 (Al₂O₃ ≥ 92%, bulk density ≥ 3.60 g/cm³) and AH-95 (Al₂O₃ ≥ 95%, bulk density ≥ 3.65 g/cm³) grades, both achieving an ultra-low wear loss (≤ 0.01%). To eliminate continuous linear seams inside round cylinders, these bricks come in versatile shapes including Rectangle Bricks, Half Rectangle Bricks, Trapezoid Bricks, Half Trapezoid Bricks, and Flake Bricks (with heights ranging from 40 to 120 mm).
