The Shortest Route to Fiber Quality, Paper360 May/June 2019

While papermakers have considerably more data today to help them navigate their processes, there are still some blind spots. For example, in the stock prep-aration area, even experienced papermakers are “flying blind” in refiner operation. Operator screens do not show how a change in applied power or fiber mix affects stock quality in the machine chest. In most cases, laboratory tests received after the sheet has already been produced are the only way to probe the stock quality. This results in outdated quality measurements that are no longer helpful, as the pulp is already processed with potentially unacceptable quality, resulting in off-grade quality.

One way to find the operational settings that produce paper within specification is to run trials with different fibers, additives, and applied power settings and then determine the corresponding effect on quality. However, on-machine trials can be risky and expensive, and off-machine trials can be inconclusive since the actual production equipment is not used.
