Alumina Ceramic Filler Balls: Properties and Applications

1. What Are Alumina Ceramic Filler Balls?

Alumina ceramic filler balls are spherical inorganic non-metallic materials made from high-purity alumina (Al₂O₃) through high-temperature sintering. With an alumina content typically ranging from 92% to 99%, they feature uniform geometry and size, widely used as packing or support materials in industrial equipment.

2. Advantages of alumina ceramic packing ball

Long Service Life: 5-10 times more durable than metal or plastic fillers.

Energy Efficiency: Minimizes downtime and energy consumption.

High Specific Surface Area: Enhances fluid distribution and mass transfer.

3. Industrial Applications

Petrochemicals: Catalyst support layers in FCC towers and adsorption columns.

Environmental Protection: Gas distribution media in exhaust treatment towers.

Pharmaceutical & Food: Reactor packing to prevent metal contamination.

Power Generation: Flue gas desulfurization (FGD) and denitrification systems.

4. Usage Guidelines

Pre-treatment: Clean equipment internals to remove contaminants.

Layered Packing: Use larger balls (e.g., Φ50mm) at the bottom, gradually reducing size upward.

Density Control: Maintain 70-80% packing density to prevent fluid channeling.

Maintenance: Annual inspection; replace if breakage exceeds 5%.

With outstanding performance, alumina ceramic filler balls have become essential in modern chemical industries. Their applications are expected to expand further with the growth of clean energy and advanced manufacturing.
