Comparison between high alumina linings brick and the rubber linings.

Comparison of advantages and disadvantages.

Aspects on quality:

High alumina linings brick.

• Inner quality: High quality Al₂O₃ is the main material, high purity.
• Grinding lost: Very good anti-grinding nature, about 1/4 to natural stone linings that is 0.02% ~ 0.027%.
• Material slurry: High purity material, slurry is very thinner.
• Other aspects: Anti-erosion, high density, high mechanical strength.

Rubber linings brick.

• Inner Quality: High organic ingredient, easy intermixes into slurry.
• Grinding lost: Near to medium / high alumina linings brick.
• Material slurry: Has affect on degree of whiteness, easy cause needle-like holes.
• Other aspects: Cushion affect to grinding, low efficiency.

HuaMing Alumina Technology provides high quality mill linings alumina brick for both batch and continuous grinding ball mill. The high density of the alumina brick can expand the milling volume and increase the ball mill productivity.

HuaMing mill linings alumina bricks are available in a wide range of thickness size from 25mm to 75mm to fit different sizes of ball mills.

Mill linings alumina brick has good performance in high impact, high abrasion resistance.

The following picture is showing how to install the alumina bricks correctly in your ball mill to achieve the best working preformace.

installation of alumina brick in ball mill

Type A: Correct installation, with trapezoid brick and rectangle brick combined correctly.

Type B: Correct installation, with only trapezoid brick applied.

Type C: Wrong installation.

Cement: Regular white Portland cement is suggested, if need corrosion resistant, then special cement is required.

Mill linings alumina brick types available: rectangle brick, trapezoid brick, flake brick, half-rectangle brick and half-trapezoid brick.
