There is a need to measure process variables spatially directly in the refining zone of refiners in the pulp and paper industry. This is accomplished by the invention and considers a control procedure where the difference between the distributed axial force and the distributed steam force for high consistency refiners alternatively the liquid and the pulp phase related forces for low consistency refiners, along the radius of the segments is used to prevent fiber cutting and plate clash of the segments. The procedure is also applicable to continuous control of the refining process near machine limits.
