Patent ID: 6875267

Claim:
A process for feeding dispersible solid fuels into a calcinator of a cement clinker production line where cement clinkers are made of cement raw meal, which raw meal is preheated in a heat exchanger, calcinated in the calcinator provided with the fuel and baked into cement clinker in a rotary tubular kiln, whereby the pre-heated cement raw meal is fed into the reaction section of the calcinator via a meal intake box that has a sloping raw meal chute and deflector slide and is arranged on the outside of the calcinator and connected to it through a wall opening, The steps comprising: feeding the fuel into the meal intake box and pre-mixing the fuel with the pre-heated raw meal there into a mixture, and then introducing the mixture via the deflector slide into the reaction section of the calcinator in order to form a gas-raw meal-solid fuel-suspension that is uniformly distributed.
