ABSTRACT:
A method and control system are provided for controlling apex flow in an array of parallel hydrocyclones, used for cleaning aqueous cellulose fiber suspensions, and arranged in a housing with a common inject chamber, base chamber and apex fraction chamber common to all hydrocyclones in the array, featuring the control of apex flow of cellulose fiber suspension by monitoring and maintaining apex flow at a selected value, increasing apex flow through the array whenever apex flow diminishes due to plugging of a hydrocyclone in the array, to aid in avoiding plugging of other hydrocyclones in the array.
