What is an Industrial Centrifuge?
An industrial centrifuge is a mechanical separation device that uses high-speed rotation to generate centrifugal forces. This force enables the rapid separation of substances with different densities, whether separating solids from liquids, liquids from liquids, or even three-phase mixtures. Industrial centrifuges operate on the principle that heavier particles migrate outward under centrifugal force while lighter components remain closer to the axis of rotation.
Why Choose a Used Centrifuge?
Investing in pre-owned centrifugal equipment offers significant advantages for process industries. Used centrifuges from premium manufacturers deliver the same separation performance as new equipment at a fraction of the investment cost. This allows companies to expand production capacity quickly, replace aging centrifuges without lengthy delivery times, or test new processes before committing to larger capital expenditures.
Choosing used centrifuge equipment also supports environmental sustainability. Manufacturing a new industrial centrifuge requires substantial raw materials and energy. By extending the operational life of existing machines through professional reconditioning, companies can significantly reduce their carbon footprint.
Additionally, premium-brand centrifuges are built for decades of reliable operation. Centrifuge equipment from manufacturers like Alfa Laval, Flottweg, and GEA represents proven technology with established spare parts availability and service networks, making used centrifuges a dependable long-term investment.
Types of Industrial Centrifuges
Industrial centrifuges are classified by their operating principle, bowl design, and discharge mechanism. At Foeth, we maintain a comprehensive centrifuge inventory spanning all major types to address diverse separation challenges.
Basket Centrifuges
Basket centrifuges are batch-operated filtration centrifuges featuring a perforated cylindrical basket lined with filter media. The suspension is fed into the rotating basket, where centrifugal force drives the liquid through the filter medium while retaining solids as a filter cake. These centrifuges excel at producing dry solids with low residual moisture and are widely used for crystalline products, pharmaceutical intermediates, and fine chemicals. Manufacturers including Heinkel, Krauss Maffei, and Ferrum offer specialised basket centrifuge designs such as peeler centrifuges, inverting filter centrifuges, and top-discharge models.
Decanter Centrifuges
Decanter centrifuges are horizontal, continuously operating centrifuges designed for high-throughput solid-liquid separation. A scroll conveyor inside the rotating bowl continuously transports settled solids to the discharge end while clarified liquid overflows at the opposite end. Decanter centrifuges handle suspensions with high solids content and are extensively used in wastewater treatment, chemical processing, food production, and mineral processing. Leading decanter centrifuge manufacturers include Flottweg, Alfa Laval, and GEA Westfalia.
Separator Centrifuges
Separator centrifuges utilise a stack of conical discs inside the bowl to multiply the effective settling area, enabling highly efficient clarification of liquids and separation of liquid-liquid mixtures. These high-speed centrifuges can separate very fine particles and are essential in dairy processing, beverage production, pharmaceutical manufacturing, and oil treatment. Alfa Laval pioneered disc stack centrifuge technology over a century ago and remains a market leader alongside GEA Westfalia and Flottweg.
Peeler Centrifuges
Peeler centrifuges feature an automated peeling knife that removes the filter cake layer by layer after the separation cycle. This centrifuge design enables fully automatic operation with consistent product quality, making peeler centrifuges ideal for continuous production of chemicals, pharmaceuticals, and food ingredients. Horizontal peeler centrifuges from Krauss Maffei and vertical peeler centrifuge designs from various manufacturers offer flexibility for different installation requirements.
Pusher Centrifuges
Pusher centrifuges are continuously operating centrifuges that use a reciprocating pusher mechanism to advance the filter cake through single or multiple basket stages. This centrifuge design achieves high throughput rates with excellent washing efficiency, making pusher centrifuges particularly suitable for salt production, mineral processing, and bulk chemical applications.
Centrifuge Applications Across Industries
Industrial centrifuges serve critical separation functions across virtually every process industry.
Centrifuges for Pharmaceutical & Biotechnology
In pharmaceutical manufacturing, centrifuges separate active pharmaceutical ingredients (APIs) from synthesis mixtures, harvest cells from fermentation broths, and clarify biological products. Hermetically sealed centrifuge designs prevent contamination and protect operators from exposure to potent compounds. GMP-compliant centrifuges from manufacturers like Heinkel and Krauss Maffei feature full CIP capability, documented material traceability, and validation support for regulatory compliance.
Centrifuges for Chemical Processing
The chemical industry relies on centrifuges for countless applications including catalyst recovery, polymer dewatering, salt crystallisation, and wastewater treatment. Centrifuges constructed from corrosion-resistant materials such as Hastelloy, titanium, and specialised alloys handle aggressive media safely and reliably. High G-forces enable efficient separation of fine particles and achieve low residual moisture in discharged solids.
Centrifuges for Food & Beverage
Food-grade centrifuges must meet stringent hygiene standards while handling temperature-sensitive products gently. Centrifuge applications range from milk standardisation and whey processing to vegetable oil refining, starch production, and beverage clarification. Hygienic centrifuge designs feature smooth surfaces, minimal dead spaces, and CIP-compatible construction for efficient cleaning between production runs.
