Abstract

An axial classifier (40), for separating the coarse particles from a fluid flow having both coarse and fine particles, comprising a housing (41) forming a first chamber (48) for the fluid flow to enter the classifier, a vane assembly (45) provided within the housing, wherein the vane assembly includes a plurality of blades (50) aligned around a flow diverter (46), a cone member (44) forming a second chamber (4) for the fluid flow to pass therein, wherein the cone member includes an opening (44c) for the coarse particles separated from the fluid flow to pass therethrough, and an outlet (43) for the particles remaining in the fluid flow after separation of the coarse particles to exit the classifier, wherein the plurality of blades (50) of the vane assembly (45) abut an outer surface of the flow diverter to direct the fluid flow from the first chamber (48) into the second chamber (49) in a manner that congregates the coarse particles for classification.

IPC Classes  ?

• B07B 4/02 - Separating solids from solids by subjecting their mixture to gas currents while the mixtures fall
• B07B 7/01 - Selective separation of solid materials carried by, or dispersed in, gas currents using gravity
• B07B 7/086 - Selective separation of solid materials carried by, or dispersed in, gas currents using centrifugal force generated by the winding course of the gas stream
• B07B 7/02 - Selective separation of solid materials carried by, or dispersed in, gas currents by reversal of direction of flow
• B07B 7/04 - Selective separation of solid materials carried by, or dispersed in, gas currents by impingement against baffle separators
• B02C 23/10 - Separating or sorting of material, associated with crushing or disintegrating with separator arranged in discharge path of crushing or disintegrating zone
• B02C 15/00 - Disintegrating by milling members in the form of rollers or balls co-operating with rings or discs
