ABSTRACT:
A method for producing a hydraulic binder using partially calcined raw meal entrained in the kiln off gases. The raw meal flow form the lowermost cyclone is interrupted at or near the junction of the meal chute, kiln inlet and riser duct. This flow interruption causes turbulence in the partially calcined meal facilitating dust entrainment in the gas. The splash plate can be selectively adjusted to entrain more or less raw meal. The entrained meal is drawn off from the riser duct through a kiln bypass duct, processed and hydrated to convert the calcium oxide in the meal to calcium hydroxide.
