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”). These units were and are referenced under the names: NX-706, ALDEC 706,
ALDEC G2-120. [More]

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.

Today, there are two basic ways of achieving your equipment needs and goals. The first and most traditional method is buying directly from the new equipment manufacturer. They provide full service including process assistance and mechanical warranties. However the customer is not getting these services free of charge. They are paying a premium for these features, which appear in high costs. There are other compromises such as:

Long delivery- Most manufactures do not inventory machines for stock. It is common to delivery times up to one year from date of the order.

Limited product lines: Manufacturers generally want to make and sell only standard models. With only a few models to choose from,

customers with special requirements often pay huge premiums for these modifications.

The other method of meeting process equipment needs is through large used equipment dealers. The benefit of this method is that used equipment dealers are not tied down to one specific manufacturer. Their concern generally is to provide equipment that will help you meet your requirements. Generally, equipment acquired this way provides you with a substantial savings over new equipment manufacturers. These dealers also can provide centrifuges “as is’ or fully reconditioned with mechanical warranties comparable to the original manufacturer. They tend to be more flexible in modifying equipment for your specific needs. Also, a few of them provide comprehensive services such as in-stock parts, start-up, field service, updating controls and drives of your existing equipment and special corrosion resistant coatings..

Advantages of buying a used centrifuge:

Cost savings of over 50% of the new price.

Immediate delivery

Trade-in allowances for your surplus equipment. [More]

Alfa Laval NX-944 Solid Bowl Decanter Centrifuge for Ethanol

In recent years a good percentage of the new ethanol plants that were commissioned to use Alfa Laval NX-944HS

solid bowl decanter centrifuges. I have an special opportunity for all the ethanol facilities that use or want to use these

centrifuges. Contact me and I can give you the details. [More]

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 . Concerning independent facilities they generally specialize in certain design centrifuges such as being a decanter facility, disc facility or a basket facility. Some do work on multiple design centrifuges. Additionally some facilities specialize in a specific design centrifuge along with a specific manufacturers. It is always best to discuss with that independent facility what centrifuges are it's main part of their business. If you would like some insight on which facility works on what centrifuges send me a note and I will be glad to assist you. [More]

Decanter Centrifuge Design Considerations

When looking at using a Decanter centrifuge for a separation application there are a couple key factors to consider during selection. First consideration is the desired phase being either the solids or the liquid. If it is the solids, do you need a dry dewatered solids or a concentrated/thickened solids. If the desired phase is the liquid and a high level of recovered solids/clean centrate must be achieved this will dictate increased pond depths in the Decanter centrifuge. These key considerations (solids or liquids) will dictate the usage of hardfacing wear protection, conveyor/scroll designs, bowl designs (angle, length & diameter), gearbox, control and backdrive requirements. If you have a application and would like to discuss your requirement, please feel free to contact me. [More]

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. The solids are removed manually by hand. Generally they are used in application with extremely low solids volumes in the feed stream since it is time consuming to remove the solids. Another design is a Desludger disc centrifuge. These design disc centrifuges will discharge the solids either by a timing control or a self-thinking control. The last basic design is a Nozzle disc centrifuge. These generally have nozzles on the side of the bowl assembly that continuously discharge the separated solids. [More]
