ABSTRACT:
The apparatus of this invention is a vertical shaft kiln designed for firing aggregate materials. In a specific application the kiln is used to fire limestone aggregate (crushed limestone) to produce lime. The kiln chamber in this apparatus is defined by an annular space between an outer vertical shaft and an inner vertical shaft. An outwardly sloping cone member defines the bottom end of the inner shaft. The bottom end of the outer shaft is defined by an inwardly sloping cone. A space between the cone members provides an outlet for the kiln chamber.
