Abstract
An on-line moisture control method for powdered or granular materials and a related system to practice the method. A fixed amount of materials are sampled by a material sampling means, transported into a heat treatment chamber having an airtight heating part, heated in the heat treatment chamber while an inert gas is supplied therein, and the weight measured by a weight measuring unit. The moisture generated by heating the materials is sent to a moisture measuring unit together with the inert gas. An operation unit receives the weight value measured by the weight measuring unit and the titrated value measured by the moisture measuring unit, and calculates the moisture content of the materials and displays the value.
