Abstract

To produce cement clinker, particulate material such as limestone, clay, iron oxide and sand is fed to a heat exchanger in which it is heated by heat supplied from a furnace. The heated material is conveyed to the furnace and sintered therein to form the cement clinker. Fuel formed from organic waste, for example motor vehicle tires, is used as the fuel.
