A centrifuge is most often used for the separation of particles from solutions according to their size, shape, density, viscosity of the medium and rotor speed. These centrifuges machines utilize the natural separation realities present in a high speed circular G-force environment. Like a high powered clothes dryer, these exceedingly fast machines spin in order to separate materials from one another. The denser materials separate from the less dense during the centrifugation process. This is helpful for the cleaning and separating of slurries which are present in many industries. The dairy industry uses centrifuges to separate milk from whey, and the food and beverage industry uses them for the washing of edible oils and the clarification of wine and juices.

Centrifuges vary in size and power depending on the substances involved in the process. Some centrifuges are able to run continuously, feeding in slurry to be separated and sending the divided substances through to outside chambers to be removed. Sometimes centrifuges are used as a step in a larger filtering process or system. Basket centrifuges work by a process in which the liquid/solid slurry is fed into the rotating basket with a filtering cloth on the slotted jacket. The liquid passes the cloth and solid is left on the basket walls. When the basket is then full of material, the machine speed is decreased and the solid is scraped from the walls of the machine. The washing and cleaning of metal parts can also take place inside of what are considered industrial centrifuges, as washers are put in a bath of cleaning solvent and then run at g-force speeds, both cleaning and separating the excess grime and sludge from the metal. The dairy, wine, beverage, and edible oil and fat industries also use industrial centrifuges for the degumming and purification of their respective products. Power and wastewater plants use centrifuges for the separation and cleansing of fuels and lubricants.

The industrial sectors of society, such as wastewater treatment plants, use centrifuges extensively for the clarification of wastewater. Power plants use them for the purification of fuel and lubricants as well as for the cleansing of metal parts, using the centrifuges like a washing machine of sorts. The primary use of a centrifuge is done by the chemical, biotechnical and pharmaceutical sectors of society. They use small laboratory centrifuges for the analyzing of proteins and drugs, and they use larger centrifuges for the purification of solvents and the concentration of other biomasses.

Many of the manufacturers of centrifuges specialize in one type, e.g. laboratory or industrial, yet others do design a wider range of types. Custom work with the manufacturer is possible in order to achieve best results. The manufacturer will work with the customer to build proper centrifuges for his or her needs, based on the materials, the volume and feed rates necessary and any cost limits. Many shops also deal in the distribution and maintenance of used centrifuges units. These may be a more cost effective way of purchasing a new or old centrifuge beyond repair capabilities.

  • Basket centrifuges are the basic type of filtering centrifuge, and consist of a basket rotating around the vertical axis.
  • Continuous centrifuges operate non-stop during a separation process, and generally contain intake and output channels to prevent buildup and ensure proper separation. Continuous centrifuges are often used in water treatment plants.
  • Disk centrifuges are used primarily for separating two liquid phases, but are also suitable for clarifying if the solid material content in liquids is small.
  • High speed centrifuges accelerate quickly and can be used for fast extraction, washing, and separation purposes.
  • Industrial centrifuges are wide ranging in styles and are used for the separation of larger volumes of liquid/solid from one another.
  • Laboratory centrifuges are an apparatus used in the laboratory for separating substances of different density or particle size, when suspended in a fluid, by spinning them about an axis in a suitable container. Used in biotechnology and other chemical industry labs.
  • Mini centrifuges are used for the separation of small samples in a laboratory setting, which includes the separation of DNA, RNA and proteins that need isolation. Mini centrifuges are sometimes referred to as a bench top centrifuge.
  • Pharmaceutical centrifuges are used for the sterile processing of drugs and the separation of other fine chemicals in the pharmaceutical industry. A type of lab centrifuge which deals with drugs only.
  • Ultracentrifuges are a high speed centrifuge used to determine the relative molecular masses of large molecules in high polymers and proteins. These can be very dangerous if maintenance is not performed regularly because of the high speeds it reaches.



Beach – In a bowl centrifuge, the dewatering part of the bowl. It is conical in shape.

Bowl – The area of a bowl centrifuge which rotates and separated solids collect.

Bowl Strips – Small thin strips of metal or other material attached to the inside diameter of the bowl used to help the settled solids convey out of the machine and to protect the inside diameter of the bowl from wear by locking in a layer of settled solids.

Cake Slids – The dryness or wetness of the discharged solids (solids phase). Usually measured as percent (%) by weight.

Centrate – The liquid (light phase) which is separated from the heavy solids (heavy phase) during the classification/clarification process, then exits through the effluent head. Centrate is also referred to as "mother liquor," "effluent" and "overflow."

Centrifugal Force – An outward force on a body rotating about an axis, assumed equal and opposite to the centripetal force and postulated to account for the phenomena seen by an observer in the rotating body.

Chatter Torque – This type of torque is generated by settled solids, resisting conveyance.

Clarification – Clearing action that occurs during wastewater treatment when solids settle out. This is often aided by centrifugal action and chemically induced coagulation in wastewater.

Conveyance Speed – Speed at which the settled solids are moved along the bowl walls and removed from the bowl.

Density – Measured in grams per cubic centimeter (or kilograms per liter); the density of water is 1.0, iron is 7.9 and lead is 11.3.

Dry Beach Area – This area de-waters the solids and allows liquid to drain back into the pool and not be discharged with the cake solids.

Gradient Centrifugation – Separates particles on the basis of their buoyant densities. A gradient range is selected to encompass the densities of all particles to be banded.

Heel – Layer of compacted solids on the inside diameter of the bowl. This layer is not conveyed out and settled solids removed by the conveyor are conveyed over this heel.

Main Bearing – The frictionless central bearing on which the bowl is supported and rotates upon.

Pillow Block – Term used to describe the central housing holding the main bearing.

Sedimentation – The process where solids suspended in water settle to the bottom of a basin.

Separation – This process divides or separates a mixture of particles or liquids into separate components.

Slurry – Pourable mixture of solid and liquid.

Supernatant – The liquid in a centrifuge tube above a pellet or sediment, after centrifugation.

Tube Size – The length of a centrifuge tube, often given in both inches and millimeters.
