Description

Wear Resistant Ceramic Alumina Protective Cover Blade Guard Ring Sleeve


Alumina ceramic part is produced by firing a tightly packed powder form of Al2O3 which includes some binder material. Commercially available grades range from 90% up to 99.95% with the higher purity generating somewhat higher hardness. Alumina Ceramics are the most highly regarded and widely used of the ceramic products. It is non-conductive, resistant to corrosion, and are perfect for electrical insulation. Alumina Ceramic has proven to be the best ceramic for protection of vital electrical components. It can be processed as tubing, sheets, bars, rods, discs, and many other forms depending on the requirements of the project.

The alumina classifier wheel blade guard ring is a wear‑resistant ceramic component specially designed for air classifier equipment. Fabricated from high‑purity alumina via isostatic pressing and precision sintering, it is installed on the edge of classifier rotor blades for anti‑abrasion protection.

It features extreme hardness, outstanding wear resistance and excellent chemical inertness. The ceramic guard ring effectively buffers high‑speed particle impact, prevents direct abrasion and erosion to metal rotor blades, greatly extending the service life of the classifier wheel. Low contamination property avoids impurity introduction into processed powder materials.

Strict dimensional accuracy ensures perfect assembly matching with classifier rotors. Custom inner diameter, outer diameter and thickness can be supplied according to customer equipment parameters and drawings. Widely used in ultrafine powder classification for minerals, new energy materials, chemical raw materials and other industries.
