Abstract
A method has been developed that estimates from the on line measurements of readily available process variables the proportion of the mass of fiber in the refining zone of a chip refiner relative to the mass with a full refining zone. This estimate of the filling factor is used to determine the margin available to load the refiner and the control action needed to avoid abnormal operation.
