CONTROL VALVE FOR FIBERIZING WASTEPAPER

摘要

Fiberizer (10) efficiency is improved by providing an inline control valve (15) at the fiberizer feed inlet which automatically provides the fiberizer (10) with make-up air proportional to the preessure differential between the fiberizer outlet (12) and the inlet. The make-up air tends to distribute the feed material (5) more evenly within the feed inlet (9) and provides a constant fiber/air ration within the fiberizer (10).
