Cyclones combine high velocity, curvature and particle concentration. Wear can intensify at the tangential inlet, follow a spiral path through the barrel and cone, then become severe at the apex or other restricted outlet. Hydrocyclones add slurry chemistry and pressure, while dry cyclones can impose fine-particle erosion and temperature constraints. Each component therefore needs its own wear map.
Equipment application guide · 03
Ceramic lining for cyclones and hydrocyclones
Protect inlet, barrel, cone, vortex finder and apex without losing the internal geometry that governs separation and flow.
Operating context01 02
Wear problem
Understand how material flow, equipment geometry and service constraints combine before selecting the lining.
Lining thickness and segmentation must preserve the approved internal profile. A change in inlet section, cone angle, vortex-finder clearance or apex diameter can influence flow and separation. Ceramic pieces, joints, attachment and tolerances should therefore be released from a controlled drawing, with the pressure or structural duty retained by the designed equipment shell.
Record the equipment and the questions that change the design
Photographs and a dimensioned drawing should accompany operating data whenever possible.
Equipment concerned
Inspect the components where trajectory, local geometry and maintenance access change.
- Tangential inlet and feed chamber
- Cylindrical barrel and cone sections
- Vortex finder and overflow components
- Apex, spigot and underflow outlet
- Dry-process cyclones and separators
- Replaceable segmented lining kits
Questions to answer
These inputs help distinguish abrasion, impact, erosion, movement and environmental constraints.
- 01Is the cyclone wet or dry, and what material and particle range does it handle?
- 02What feed flow, solids concentration, pressure and temperature define the operating envelope?
- 03Where is wear observed: inlet, barrel, cone, vortex finder or apex?
- 04Which internal dimensions and tolerances are process-critical?
- 05How will each segment be retained, installed, inspected and replaced?
- 06What are the consequences of a loose part entering the underflow or downstream process?
Design ceramic, geometry and retention as one construction
Each principle must be checked against the selected product grade, equipment owner requirements and installation conditions.
- 01
Build a component wear map
Record inlet impingement, spiral wear, outlet restriction and previous failure boundaries instead of assigning one uniform duty to the full cyclone.
- 02
Preserve process geometry
Control finished bore, inlet area, cone profile, clearances and apex diameter on the lining drawing and during inspection.
- 03
Segment for manufacture and maintenance
Use numbered, positively located parts with practical handling size, controlled joints and a replacement sequence suited to access.
- 04
Match material to each zone
Conventional alumina, selected ZTA or custom shapes are evaluated from local abrasion, impact, temperature, chemistry and support rather than a single catalogue label.

Conditions that can change or exclude the proposed construction
These points should be resolved before quotation, drawing approval or installation planning.
- 01
Any change to process-critical internal geometry should be reviewed by the equipment or process owner.
- 02
The equipment shell retains pressure and structural duties; ceramic does not repair an unverified pressure boundary.
- 03
Tight tolerances, inaccessible joints and complex shapes may require custom manufacture and controlled trial assembly.
- 04
Chemistry, temperature and cleaning conditions must be checked for ceramic, bond line, grout and steel shell as a system.

Questions before specifying the lining
Why are custom ceramic shapes often considered for cyclones?
Cyclones contain compound curves, tapers, tangential entries and restricted outlets. Custom or segmented shapes can preserve coverage and internal profile with fewer vulnerable cuts, subject to manufacturability and tolerances.
What information is needed from the existing cyclone?
Provide controlled drawings, actual internal measurements, process conditions, material data, photographs, wear history, current liner construction and the dimensions that control separation performance.
Can one ceramic grade be used throughout?
Possibly, but it should not be assumed. The inlet, cone and apex can experience different impact, velocity, support and geometry; a zoned material or thickness strategy may be appropriate.
How are replacement parts controlled?
Use an approved revision, part numbers, orientation marks, material identification, dimensional inspection and an installation map. Spare strategy should reflect the zones that actually wear fastest.
