What is a decanter centrifuge used for?
Description of a Decanter Centrifuge A decanter centrifuge, also known as a horizontal bowl centrifuge, solid bowl centrifuge or scroll centrifuge, is a machine used to separate a solid material from a liquid(s) using a high-speed and continual rotational process.
How much does a decanter centrifuge cost?
Decanter centrifuges are considered capital equipment based on their expected operating life and durability. Their price depends on the manufacturer and size/capacity. A new machine (from a quality, established manufacturer) starts from around $50K for a small capacity unit to over $1M for a large capacity machine.
When would you use a decanter centrifuge?
The main application of decanter centrifuges is to separate large amounts of solids from liquids on a continuous basis. They are also used to wash and dry various solids in industry, such as polystyrene beads, clarify liquids and concentrate solids.
What is decanter machine?
A decanter centrifuge separates solids from one or two liquid phases in one single continuous process. This is done using centrifugal forces that can be well beyond 3000 times greater than gravity.
What is the difference between decanter and centrifuge?
The main differences between a decanter and disc-stack centrifuge are: A decanter centrifuge’s axis of rotation is horizontal, whereas a disc-stack centrifuge bowl rotates around a vertical axis. A decanter centrifuge typically separates particles, which are 100 microns or larger.
How does an oil decanter work?
A decanter centrifuge separates solids from one or two liquid phases in one single continuous process. This is done using centrifugal forces that can be well beyond 3000 times greater than gravity. The centrifugal force compacts the solids and expels the surplus liquid. The dried solids then discharge from the bowl.
How does a decanter function?
A decanter is a vessel that is used to hold the decantation of a liquid (such as wine) which may contain sediment. Decanters, which have a varied shape and design, have been traditionally made from glass or crystal. Their volume is usually equivalent to one standard bottle of wine (0.75 litre).
Why are centrifuges used in Alfa Laval decanters?
Alfa Laval decanter centrifuges help you separate solids from liquids within one single continuous process. Stand out from the competition with high performance separation that results in extracted / clarified products of excellent quality and higher commercial value.
How does a screw decanter centrifuge work?
Working Principle of Screw Decanter Centrifuge A screw decanter centrifuge is gradually accelerated by the frequency converter. The main and auxiliary pulley drives the machine. After that, the drum and the input shaft of the differential reaches the rated speed.
What kind of steel is used in Alfa Laval decanters?
Rotating components of Alfa Laval decanter centrifuges exposed to high stress are machined from high-strength centrifugally cast stainless steel. This ensures castings with a uniform grain structure free from flaws and defects as well as a completely weld-free finished component.
What kind of particles can a Laval decanter handle?
The units are designed to handle a wide range of particles with diameters from 5 mm to a few microns. With their high efficiency, continuous operation, low capital cost/capacity ratio, low maintenance costs and low energy consumption, the decanter centrifuges are ideal to use in a range of duties including process, food and waste applications.
