Alumina Ceramic Cone

Alumina Ceramic Cone

In coal preparation plants, dense medium cyclones are critical for separating coal and impurities. However, the inner wall of the cyclone is subjected to intense abrasion from high-velocity slurry. Our alumina ceramic cone is specially engineered to serve as a wear-resistant liner for the main body of the cyclone.Cylindrical shape has a low friction coefficient. During use, the inner diameter changes slowly, ensuring high and stable sorting efficiency.

Description

Alumina Ceramic Cone

What Is an Alumina Ceramic Cone?

An alumina ceramic cone is a monolithic wear liner made from high-purity alumina (Al₂O₃), precision-formed into a conical shape that fits directly into the lower section of a dense medium cyclone. Unlike segmented ceramic tiles or liners, the cone offers seamless protection with superior mechanical strength and wear resistance.

Advantages Over Traditional Ceramic Tile Liners

Feature Alumina Ceramic Cone Traditional Ceramic Liners
Structure One-piece, conical body Segmented tiles, jointed surface
Wear Resistance Excellent, uniform surface May wear at joints or edges
Installation Time Fast and simplified Requires careful tile placement
Risk of Detachment Low (no adhesive failure) Higher risk at tile interfaces
Fluid Dynamics Smooth, turbulence-free surface Potential for flow disruption

 

Key Features of Our Ceramic Cyclone Cones

Material: 92–95% high-purity alumina

Hardness: Mohs scale 9 – second only to diamond

Temperature Resistance: Up to 1,100°C

Density: ≥ 3.6 g/cm³ for enhanced impact resistance
