ABSTRACT:
A flow management system and process for providing controlled separation and sizing of an incoming flow of wood chips. A flow management screen is provided in the form of a horizontal disk screen having a variable speed drive, with the drive controlled based upon the flow rate of wood chips to the screen. By controlling the rotational speed of the disks of the horizontal disk screen, the flow separation and sizing to subsequent screening stations can be predicted and controlled. As a result, more consistent output is provided, as well as improved system efficiency and ability to accommodate for varying operational conditions and wear.
