“…Unfortunately, these bars with trapezoidal shape shortened the service life with rapid reduction of both bar sharpness and stock throughput in the grooves between adjacent bars during refining. 12,13) An innovative approach to fabricating lightweight fine bar plates is developed by employing aluminum alloy, AC1B, for the plate base and stainless steel, 420J2, for the bars. 14) The joining of these dissimilar metals for DP was achieved using a specialized technique, as illustrated in Fig.…”

Two thermomechanical pulp (TMP) refiner plates with different cutting edge length (CEL) were designed and manufactured to assess their impact on energy consumption, fiber properties, and pulp quality. Under the same refining conditions, refiner plates with higher CEL, referred to as TMP casting plates (TP), consumed more refining power than those with lower CEL, denoted as lightweight TMP plate (DP). TP with high CEL exhibited reduced fiber length loss and maintained low fiber coarseness in TMP and CTMP. TP resulted in superior strength development, while DP with smaller CEL were more effective in reducing shive content because of high-intensity refining. Consequently, it is worth considering different patterned plates to reduce refining energy consumption, minimize fiber length loss, and achieve superior strength development during TMP and CTMP manufacturing.

This study conducted a comparative analysis of two refiner plates that had different bar patterns. The plates were designed with three distinct zones, including the high-intensity zone, the transition zone, and the low-intensity zone, and had a draft angle of 4–5 degrees. The two refiner plates had a significant difference in cutting edge length (CEL) of approximately four times. Specifically, TMP plate A (TP A) had a CEL of 5.1 km/s, while plate B (TP B) had a CEL of 22.7 km/s, indicating that TP A applied greater force to the wood chips during refining. TP A exhibited greater stock throughput at the same refining energy compared to TP B due to its smaller CEL. The low-intensity refining of TP B promoted the fibrillation of TMP fibers, leading to a large decrease in fiber width without significantly changing the mean fiber length before and after refining. The bulk of TMP and CTMP increased slightly more in TP B than in TP A. However, TP A showed a greater decrease in tensile strength due to a larger decrease in fiber length, whereas there was no significant change in tear strength between the two plates.
