Centrifugal Cleaner

A centrifugal cleaner uses tangential feed to create a high-speed vortex. Dense contaminants such as sand and metal particles move along the cone wall into the underflow, while accepted stock exits through the vortex finder at the top. The ceramic cone, inlet, underflow nozzle and reject outlet are major erosion zones.

Major Components and Assemblies

Individual and Maintenance Parts

Ceramic Cone

Technical Requirements: Confirm alumina and SiC ceramic hardness against the specific grade and material certificate, and protect the ceramics from external impact.

Underflow Nozzle

Technical Requirements: The bore size controls underflow; set the wear limit by the permitted increase in bore diameter.

Vortex Finder

Technical Requirements: Requires erosion resistance, concentricity and chip-free inlet edges.

Cleaner Body

Technical Requirements: Accept 316L properties against the product form, material standard and certificate; finish weld surfaces according to the specified procedure.

Feed Inlet Liner

Technical Requirements: Consider ceramics at high-velocity tangential inlets and resilient composite structures where impact is greater.

Accepts Outlet Liner

Technical Requirements: Keep surfaces smooth to prevent fibre accumulation and crevice corrosion.

Rejects Outlet Liner

Technical Requirements: Consider harder materials in sand-rich reject zones and control steps between adjoining sections.

Gaskets / seals

Technical Requirements: Select EPDM, FKM or PTFE for the actual stock, temperature, cleaning media and seal design.

Mounting Bracket

Technical Requirements: The support must withstand the weight of the fully flooded bank, vibration and maintenance loads.

Materials for similarly named parts may differ by OEM, machine model and operating conditions. Confirm the machine model, OEM drawing number and measured dimensions before ordering or manufacture.

Manufacturing Services in China

From Technical Assessment to Finished-Part Delivery

ANRANST provides customers worldwide with engineering assessment, production at certified foundries to drawing, quality control and finished-part delivery for custom wear parts and industrial spares, with scope to support other custom industrial parts.

Drawing and Engineering Review

We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.

Material and Heat-Treatment Specification

Material grades and heat-treatment processes are specified order by order, confirmed in the technical agreement and tracked through production.

Quality Control

Drawing confirmation, material and process control, production tracking, inspection and acceptance coordination.

Finished-Part Delivery

We coordinate manufacturing, quality confirmation, packaging and delivery of complete finished parts in a workable, closed-loop supply process.

Provide the existing model, drawings, drawing or part numbers, materials or operating conditions so we can identify the appropriate technical review and supply route.
