A mathematical model was developed by correlating the experimental values of tile chacteristics with the mass fractions of raw mixture components, whose particle size distribution was known and supplemented with the general constraints (such as the mass balance equation and the conditions of non-negativity). A typical problem was solved by a combined analytical-numerical procedure and by the geometric programming method.
The results of the two methods were compared and those of the latter were found to be preferable. |
