Abstract
Abstract This paper describes forces in pulp refiners and their influence on fibre shortening. We show that force per bar length obtained by a simple calculation from the Specific Edge Load ( SEL ) is a useful parameter to describe threshold force levels below which levels of fibre cutting can be avoided. Our analysis is supported by data from studies on four refiners and in one case by direct measurement of force in an operating refiner. In particular, we show that small bar widths lead to large forces and consequently that SEL must be adjusted to lower levels to avoid fibre cutting. We also speculate on the lower limits of bar width.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
