Over 30 years, a large paper mill located in the United States has worked closely with ABB to continually optimize automation equipment performance and, as a result, increase productivity, maximize uptime and raise product quality.
The paper mill produces more than 400,000 tons per year of specialty papers on four paper machines. The mill also has a woodyard, a bleached kraft pulp mill with eight batch digesters, four boilers, a coater and converting operations.
As the product mix diversified and printing and converting equipment evolved, so did the need for more consistent quality. Variability reduction is an important part of the mill‘s continuous improvement. Three of the four paper machines had ABB Quality Control Systems (QCS) installed. ABB supported the mill with several weeks of optimization services, including a Paper Machine Fingerprint assessment on a paper machine in 2009. In 2010, ABB won the order to replace the machine's QCS with an ABB system. The paper mill chose an ABB 800xA QCS that included two ABB Network 1200 scanning platforms, one at the size press and one at the reel. The mill selected the ABB QCS system for improved caliper measurement and control.
