Method and apparatus of controlling granulation of moisture-absorbing powder material

摘要

A control method for a granulating apparatus of the type in which a binder liquid is added to powder material having high moisture absorbing properties while fluidizing the powder material thereby producing granules or granular material of a desired particle size. In this control method, the moisture content of powder material to be granulated is continuously detected with a high degree of accuracy by a moisture content detector and in accordance with the detected value the rotation speed of a binder feed pump or the like is adjusted through a moisture content regulator thus varying for example the rate of addition of the binder and thereby controlling the moisture content of the powder material.
