A system and method of determining clinker composition and optimizing raw material and fuel feed rates for a cement kiln plant is provided. Raw material data, fuel data, clinker kiln dust data, and emissions data are received. At least one of a raw material feed rate, a fuel feed rate, and an expected clinker composition are calculated based on the raw material data, the fuel data, the clinker kiln dust data, and the emission data. At least one of the raw material feed rate, the fuel feed rate, and the expected clinker composition are outputted.
