Abstract:
Method for the preparation of granulated material by spraying at least one additive in liquid form onto a flowing stream of the material, comprising the steps of:ejecting an even, flat stream of the material from a dispenser onto an upper end of an inclined chute at a predetermined speed by a driven ejector arrangement; determining a mass flow rate of the material in the flat stream; spraying said at least one additive onto the stream of material sliding down the chute as it passes under the spraying station at a lower portion of the chute; adjusting at least one of said predetermined speed at which the flat stream of the material is ejected from the dispenser and a spray volume of said at least one additive sprayed onto the stream of material in said spraying step as a function of mass flow rate determinations produced as said stream of material slides down the chute so as achieve a substantially constant liquid dosing per unit weight of the material.
