Abstract
A mathematical model and a computer model were developed for the multistage chemical and energy engineering process of roasting of phosphorite pellets, which includes the reactions of dissociation of carbonates and the processes of sintering in a moving dense multilayer mass of phosphorite pellets in a complex chemical and energy engineering system—travelling grate machine. The adequacy of the developed mathematical model was tested. Computational experiments were performed to determine the roasting process parameters at various physicochemical characteristics of the phosphate feedstock and the external heattransfer gas flow.
