Mohs 9 Ceramic Wear Bricks for Longer Mill Life

Product Overview

HUAO Alumina Ceramic Wear-Resistant Bricks are ultra-durable protective linings designed to defend ball mills and heavy-duty industrial pipelines against severe impact, sliding friction, and liquid erosion. Manufactured in standard AH-92 (Al₂O₃ ≥ 92%) and premium AH-95 (Al₂O₃ ≥ 95%) grades, these high-density white ceramic bricks combine extreme Mohs 9 hardness with near-zero wear loss.

Engineered in various specialized shapes — including Rectangle, Trapezoid, Flake, and corresponding Half Bricks — they fit seamlessly inside cylindrical shells to absorb material impacts, drastically extending overall equipment service life and improving milling efficiency.

Key Features

• Rated at Mohs 9, these ceramic bricks resist relentless impact and sliding wear caused by grinding media and dense slurries.
• Delivers a bulk density of ≥ 3.60 g/cm³ (AH-92) to ≥ 3.65 g/cm³ (AH-95), effectively absorbing kinetic shock loads.
• Available in rectangular, trapezoidal, and thin flake configurations, facilitating tight interlocking arrangements along curved internal mill walls.
• Features minimal wear loss (≤ 0.01%) and chemical inertness, protecting against corrosive liquid slurry flow and contamination.

Advantages

• Maximized Ball Mill Grinding Volume: Compared with metal lining, bricks increase the effective workload inside the ball mill and improve processing capacity.
• Extended Lifespan & Reduced Maintenance: Good wear resistance effectively extends the service life of the equipment, reduces maintenance frequency and replacement costs.
• Zero Chemical Contamination: High purity white ceramic components can prevent iron or metal from falling off during milling, maintaining the purity and color quality of the final product.
• Optimized Shell Energy Efficiency: Seamless trapezoidal fittings reduce the gap between the inner lining and lower the energy consumption per ton of grinding material.

Applications

These alumina ceramic wear resistant bricks are widely used in ball mills and industrial piping systems in the ceramic, mining, steel, power, cement, and chemical industries. As protective liners, they can protect equipment walls from severe material impact and continuous wear, effectively preventing premature equipment failure.

Customization & Packaging

We offer customized sizes and shapes of bricks to suit specific ball mill shell diameters and pipe configurations. In order to protect the goods during sea transportation, the products are safely packaged in heavy-duty cardboard boxes with internal moisture protection, and then placed on sturdy fumigated or non fumigated wooden pallets and shrink wrapped. Customizable packaging, OEM logo printing, and customized shipping marks can be provided according to customer requirements.
