Abstract

A method for regulating the cooling of loose or flowing material by adding water and evaporating it, characterized in that within a moving current of the loose material, at two measuring points arranged one after another and whose separation is given for the difference, as a function of time, between the high situation and the low temperature situation before and after the cooling of the relevant loose material, the temperature of the loose material is measured in each of them, the first measuring point governing the water supply, placed immediately behind it, as a function of the temperature of the loose material that arrives, while the second measurement location originates, in correspondence with a difference, positive or negative, with respect to a preset temperature, after cooling, the connection of another regulating organ that carries out a correction of the adjusted water supply in a manner governed by the first measurement point, in proportion to the temperature difference between the first measurement point and the second.
