An Alumina Ceramic Hydrocyclone Liner is a replaceable wear insert installed inside a hydrocyclone (cyclone separator) to protect the cyclone body from abrasive slurry erosion and to keep the cyclone’s internal flow geometry stable during operation.
Alumina Ceramic Hydrocyclone Liner Advantages
-
Geometry retention focus: The alumina ceramic hydrocyclone liner is built to maintain a stable cone angle and internal ID profile over wear life, so the cyclone’s hydraulic geometry changes more slowly and separation performance stays closer to the initial setup.
-
Targeted wear-zone design: The liner can be designed with localized wall-thickness zoning in the highest-velocity impact band of the cone and near transition areas, which helps slow “grooving” and uneven thinning without adding unnecessary mass to low-wear regions.
-
Repeatable assembly fit: Controlled mating details such as seating length, shoulders, and step features support consistent positioning inside the cyclone body, reducing rocking, bypass flow at interfaces, and the localized edge erosion that often starts around misaligned joints.
-
Kit-ready modularization: The alumina ceramic hydrocyclone liner can be structured as a modular set (barrel + cone + adapter sections) so the most-worn section can be replaced independently, while preserving the same internal flow-path geometry and avoiding a full liner teardown each time.
-
Erosion-path control: Internal transitions can be designed with smoother blends and minimized internal steps at section joints, helping reduce turbulence-driven hotspots that accelerate wear and cause early failure at seams, ends, or abrupt profile changes.
