Bar-Edge Length Comparison: Tensile Strength by Refining Energy

Published research on two refiner plate patterns with different bar-edge lengths (BEL) shows how much geometry alone changes fiber-strength outcomes on the same recycled-fiber (OCC) furnish. Toggle between the two comparison points below.

50.5
Narrower BEL Plate
(0.99 km/rev)
53.0
Wider BEL Plate
(2.01 km/rev)

Tensile Index (Nm/g) — higher is stronger pulp at the same processing point

Source: Cai, H. et al. (2020), BioResources 15(1), 347-359 — independent academic testing. Figures illustrate how much bar-pattern selection alone moves fiber-strength outcomes; not a claim about any specific Zejiang plate pattern.
Two plates from the same equipment family can perform very differently. Send your bar pattern or a worn sample so we can match geometry, not just brand and model.
