The permeability of sinter mix is one of the vital parameters that affect the performance of sintering process. The amount of water added in the granulation drum has a significant effect on the permeability of the sinter bed and sinter machine productivity. Considering the variation in input feed materials and the parabolic nature of permeability-moisture curve, the optimum level of water addition is a difficult task for the operator to determine. Therefore a mathematical model based intelligent permeability measurement system is developed which determine the required amount of water to be added in granulation drum to achieve the optimum permeability based on the given input material.
