Abstract
A classifier including a housing, a body, a vane assembly, and an outlet. The housing extends along a longitudinal axis between opposing first and second ends, and includes a lower portion provided at the first end and including an inlet, an upper portion provided at the second end and including a reclaim outlet, and an intermediate portion provided between the upper and lower portions. The body is disposed within the housing that defines a chamber therebetween. The vane assembly includes a plurality of blades and is provided between an outer surface of the body and an inner surface of the intermediate portion dividing the chamber into first and second chambers. The outlet is provided at the second end and is fluidly connected to the second chamber to allow fine particles separated from coarse particles to flow through the outlet. The reclaim outlet is fluidly connected with the second chamber and a pulverizer to allow coarse particles separated from the fluid flow to be directed back to the pulverizer.
