Abstract
A method is disclosed. The method includes depositing a source material (M) consisting of blast furnace slag into a closed-loop centrifugal air classifying system (10, 10′, 10″) and utilizing the closed-loop centrifugal air classifying system (10, 10′, 10″) for processing the blast furnace slag into a processed blast furnace slag material (Mp). A closed-loop centrifugal air classifying system (10, 10′, 10″) is also disclosed.
Claims30
A method, comprising:
- depositing a source material consisting of blast furnace slag into a closed-loop centrifugal air classifying system;
- and
- utilizing the closed-loop centrifugal air classifying system for processing the blast furnace slag into a processed blast furnace slag material.
A closed-loop centrifugal air classifying system, comprising:
- a classifier and vertical grinding mill;
- a cyclone collector fluidly connected to the classifier and vertical grinding mill by a first duct segment of a plurality of duct segments;
- a fan fluidly connected to the cyclone collector by a second duct segment of a plurality of duct segments, wherein the fan is fluidly connected to the classifier and vertical grinding mill by a third duct segment of a plurality of duct segments;
- and
- a hot air source fluidly connected to one of the classifier and vertical grinding mill and the cyclone collector.

A method, comprising:
- depositing a source material into a material entry opening of a closed-loop centrifugal air classifying system, wherein the material entry opening is formed by one of a classifier and vertical grinding mill and a cyclone collector of the closed-loop centrifugal air classifying system;
- fluidly connecting a hot air source to one of the classifier and vertical grinding mill and the cyclone collector for
- decreasing density of air within the closed-loop centrifugal air classifying system, and
- drying the source material that is located within the closed-loop centrifugal air classifying system;
- utilizing the closed-loop centrifugal air classifying system for processing the source material into processed material;
- and
- recovering the processed material from a material exit opening formed by the cyclone collector.
