B04B CENTRIFUGES
Introduced: September 1968
Classification Context
- Section:
- PERFORMING OPERATIONS; TRANSPORTING
- Class:
- CENTRIFUGAL APPARATUS OR MACHINES FOR CARRYING-OUT PHYSICAL OR CHEMICAL PROCESSES
- Subclass:
- CENTRIFUGES
Description
B04B covers centrifuge machines and apparatus designed to separate substances or materials using centrifugal force. This subclass encompasses various centrifuge types including laboratory, industrial, and continuous-operation models used for solid-liquid separation, liquid-liquid separation, and particle classification across chemical, pharmaceutical, food processing, and environmental applications. Related mechanical components such as rotors, bowls, baskets, and drive systems integral to centrifuge operation are included within this classification. Adjacent classes B04C (auxiliary equipment for centrifuges) and broader class B04 (centrifugal apparatus for physical/chemical processes) provide complementary coverage for supporting equipment and non-centrifuge centrifugal machines.
Scope Notes
Glossary: Centrifuge Centrifuges Machine or apparatus for separating, mixing, drying, extracting, purifying, or like treating in which centrifugal effects are generated by rotary bowls or other rotors. Where such a machine or apparatus involves pumping effects, such effects must be incidental or subsidiary to the treating. | Limiting references: High-speed drum mills Cyclone separators | Application references: Centrifuges for producing filtered coffee Dental appliances for receiving spittle, with or without rinsing means therefore, e.g. dental basins, spittoons or cuspidors Suction or pumping devices for medical purposes, other treatment of blood in a by-pass of the natural circulatory system Processes for separation of non-miscible liquids by centrifugal force Processes for using centrifuges for separating sediment Processes for separating dispersed particles from gases or vapours by gravity, inertia or centrifugal forces , Processes for separation of gases or vapours or for recovering vapours of volatile solvents from gases by centrifugal force Processes using centrifugal force for selective separation of solid materials carried by, or dispersed in, gas currents Centrifugal casting machines Treatment of water, waste water or sewage by centrifugal separation Domestic spin dryers Lubrication of machines or engines in general, details of lubricant purifying means Exhaust or silencing apparatus for machines or engines having means for removing solid constituents of exhaust, using inertial or centrifugal separators Drying solid material by using centrifuges
