A process and apparatus for producing calcium sulfide is provided comprising a container housing one or more drums, each drum having a substantially horizontal longitudinal center axis and containing one or more screw conveyors therein. Multiple drums are connected by passageways, and passages are provided for passing material into and out of the container and the drum(s). A heater is provided for supplying heat to the material within the drum(s). The process comprises passing the reactants, gypsum and charcoal, into the container and drum(s), heating the reactants within the drum(s) thereby initiating a chemical reaction converting reactants to products (including calcium sulfide), moving the reactants and products substantially horizontally in the drum(s) through the use of the screw conveyor(s) contained therein, and passing the products out of the drum(s) and the container.
