Abstract
Disclosed is a process for the calcining and manufacturing of synthetic pozzolan with desirable color properties. Feed material is dried, crushed, and preheated in a drier crusher. The dry, crushed material is collected and fed to a calciner where it is heated to become a synthetic pozzolan. The synthetic pozzolan is then fed to a cooler where it is maintained for a least a portion of the cooling step in a reducing atmosphere.
