This patent describes a suspension shaft furnace for producing discrete cement clinkers from discrete pellets of cement-forming batch materials which are gravity-migrated therethrough. It comprises a vertical furnace housing enclosing a top pellet-feeding and preheating zone comprising an elongate vertical shaft section opening into an intermediate fluidized bed section comprising fuel inlet conduits, an air-permeable clinker-impermeable support; a lower clinker-cooling section beneath the fluidized bed section; clinker-discharge means communicating between the fluidized bed section and the cooling section and air inlet means.
