SEPARATING AND MIXING

|  | B01 |
PHYSICAL OR CHEMICAL PROCESSES OR APPARATUS IN GENERAL (furnaces, kilns, ovens, retorts, in general Fulltext... Hierarchy... Expanded...F27)

|  | B01B |
BOILING; BOILING APPARATUS

|  | B01D |
SEPARATION (separating solids from solids by wet methods Fulltext... Hierarchy... Expanded...B03B, Fulltext... Hierarchy... Expanded...B03D; by pneumatic jigs or tables Fulltext... Hierarchy... Expanded...B03B; by other dry methods Fulltext... Hierarchy... Expanded...B07; magnetic or electrostatic separation Fulltext... Hierarchy... Expanded...B03C; centrifuges, vortex apparatus Fulltext... Hierarchy... Expanded...B04)

|  | B01D |
Note(s) The processes covered by this sub-class include evaporation, distillation, crystallisation, filtration, dust precipitation, gas cleaning, absorption, adsorption. This sub-class also includes similar processes which are not concerned with, or limited to, separation (except in the case of absorption or adsorption). The word "filtration" and related words should be interpreted as embracing straining liquids from solids. For apparatus used in drying or evaporation, Fulltext... Hierarchy... Expanded...F26 takes precedence over Fulltext... Hierarchy... Expanded...B01D. When considering the sub-divisions of this sub-class, it should be borne in mind that group Fulltext... Hierarchy... Expanded...B01D 59/00 takes precedence over the other groups of this sub-class and over other sub-classes.

MIXING, e.g. DISSOLVING, EMULSIFYING, DISPERSING

|  | B01F |
Note(s) The term "mixing" also covers stirring of a single material. [2]

|  | B01J |
CHEMICAL OR PHYSICAL PROCESSES, e.g. CATALYSIS, COLLOID CHEMISTRY; THEIR RELEVANT APPARATUS (processes or apparatus for specific applications, see the relevant classes for these processes or apparatus) [2]

|  | B01J |
Note(s) The term "solid particles" is to be read as covering such particles whether catalysts, reactants or inert in solid, semi-solid or pasty state. [2] "Fluidised particles" are to be understood as finely divided solid particles lifted and agitated by a stream of fluid. "Fluidised-bed technique" relates to fluid-solid contacting technique in which finely divided particles are lifted and agitated by a rising stream of fluid, said stream having such a speed as to form a lower dense phase (the "bed") and an upper dilute fluidised phase of "fluidised particles". [2] The expression "processes conducted in the presence of solid particles" is considered not to include processes wherein the only solid particles present are formed during the reaction. [3]

Note(s) This sub-class is intended to take only laboratory apparatus which is either applicable solely to laboratory purposes or which, by reason of its simple construction and adaptability, is such as would not be suitable for industrial use.
