They are essential for pharmaceuticals, food processing, and chemical manufacturing. This guide will break down the different types of basket centrifuges, their functions, and their applications.

Key Considerations For Used Centrifuge Buyers

Buying a used industrial centrifuge can be a smart financial move for your business. However, it's essential to understand what you're investing in. Several factors must be considered to ensure your purchase meets your operational needs. This guide will provide you with five critical aspects to evaluate. From assessing condition and maintenance to understanding performance specifications, we cover everything you need to know. Whether you prioritize versatility, safety, or cost considerations, this used industrial centrifuge buying guide will help you make an informed decision.

Finding Quality Used Centrifuges For Sale

In the world of laboratory and industrial operations, centrifuges are indispensable. They play a crucial role in various sectors, from pharmaceuticals to environmental services. However, acquiring a new centrifuge can be a significant investment. This is where used centrifuges come into play.

Purchasing a used centrifuge can offer substantial cost savings without compromising on quality. But how do you find a reliable, high-quality used centrifuge for sale? This guide aims to provide you with valuable insights on finding and purchasing the best used centrifuges. Let's dive in.

Your Guide To Specialty Centrifuges

In science and industry, centrifuges play a vital role in separating substances based on density. From medical labs to manufacturing plants, these powerful machines are indispensable. However, not all centrifuges are created equal. Specialty centrifuges are designed for specific applications, offering enhanced performance and efficiency. This guide will walk you through the various types of specialty centrifuges, helping you understand their unique functions and benefits.

To Disc or Decant: Which Centrifuge Is Right For Me?

Both decanter and disc stack centrifuges are used for solid-liquid separation, but they excel in different applications. Read a breakdown of when to each type of centrifuge.

Basic Centrifuge Designs

Centrifuges are basically categorized into six types (Decanter, Disc, Basket, Pusher, Peeler, Tubular Bowl). A Decanter Centrifuge come in two general designs - Solid Bowl or Screen Bowl. A Basket Centrifuge is either perforated or solid bowl design.

Use of Centrifuges for Rendering

If your business operations entail conversion of animal waste into more useful, value-added materials like lard or tallow, then you know how essential a centrifuge is to accomplishing that aim. Maybe you are on the hunt for a new, reconditioned or used centrifuge to replace your current one, or perhaps you are entirely new to the world of rendering. Either way, shopping for a centrifuge can be confusing. We hope this primer will help make the purchasing process less baffling for you.

Centrifuges for Wastewater Treatment

https://www.aaronequipment.com/usedequipment/centrifugesCentrifuges’ use in the treatment of wastewater enjoys a longstanding history. According to the United States Environmental Protection Agency’s (EPA’s) Office of Water, “Centrifuges have been used in wastewater treatment since the 1930s.1” During that 80+ years of usage, centrifuges have helped separate wastewater solids from liquid, thereby ridding it of contaminants.

Centrifuge Reconditioning

If you have a centrifuge or are going to buy a used centrifuge, which you intend to have reconditioned here are a couple of thoughts to consider. Your first choice is to use the centrifuge manufacturer or a independent centrifuge reconditioning facility. The manufacturers all perform the proper reconditioning but at a very costly price. In recent years some of the manufacturers have branched out to other brand centrifuges to keep their facilities busy, but price still be a factor in this scenario.

Westfalia CA-505 Decanter Centrifuge

Westfalia manufactured CA-505 solid bowl decanter centrifuges. They have been put to use in the wastewater, chemical, starch and ethanol industries. The rotating assemblys measure 20.1" diameter by 80.4" long. They are offered in a standard cyclo design and a two-gear design. The two-gear design permits automatic torque measurement and differential speed control. 

Alfa Laval NX-706 Decanter Centrifuge designations.

Alfa Laval has changed designation for a NX-706 decanter numerous times over the years.Of course in the progressing designation changes they have made design changes, but the centrifuge rotating assembly dimensions have remained the same at 740mm (29”) diameter by 3019mm (118”).

The Proliferation Of Centrifuges Into The Waste, Chemical, Pharmaceutical, Food Industries.

The proliferation of centrifuges into the waste, chemical, pharmaceutical, food and metal working industry has created a demand for high quality equipment to meet current process needs and requirements.

Decanter Centrifuge Design Considerations

When looking at using a Decanter centrifuge for a separation application there are a couple of key factors to consider during selection.  The first consideration is the desired phase to be either the solids or the liquid.  If it is the solids, do you need dry dewatered solids or a concentrated/thickened solids. 

Disc Centrifuge Designs

Disc Centrifuges come in three basic designs.  One is a Solid Bowl, which retains the solids on the inside diameter of the centrifuge bowl assembly.  The solids are removed manually by hand.  Generally they are used in applications with extremely low solids volumes in the feed stream since it is time consuming to remove the solids. 

Well Known Centrifuge Manufacturers

I have listed below a selection of the more know centrifuge manufacturers pertaining to industrial centrifuges:  Alfa Laval, Andritz, Bird, Carr, Centrisys, Cinc, Delaval, Derrick, Dorr Oliver, Escher Wyss, Flottweg, Guinard, Hutchinson Hayes, Hysep, IHI, Kokusan, Krauss Maffei, Pieralisis, Podbielniak, Rouselett, Sharples, Swaco, Tema, Tomoe, US Centrifuge, Westerns States, Westfalia.

Two Types of Centrifuge Separation

In the usage of a centrifuge you have two designs based on general physic rules.  One design is based on filtration via spinning the feed material at a increased "G" force allowing the liquid phase to pass through a filter media leaving the dewatered solids on the filter media.
