Abstract
An apparatus and method for the treatment of fine grained materials including a calcining furnace, a plurality of cyclone separators arranged in series, with exhaust means delivering exhaust gases from the calcining furnace to one of the cyclone separators, with at least the first two of the plurality of cyclone separators being at substantially the same vertical height. Supplemental combustion means consisting of a fuel injection means and a combustion air injection means are included in the path of the exhaust gases passing from the furnace through the plurality of cyclone separators to render the system more efficient and to reduce the size of the components.
