Improved paper pulp control at Crown van Gelder.
Result:40% reduction in grinding fluctuationsCrown van Gelder is a paper producer. When paper is produced from pulp, the grinding of the pulp must be performed with minimal fluctuations, while the pulp level in the mixer (tank) must remain within fixed limits. DotX has changed the control system in January 2008 in such a way that the grinding fluctuations reduced by more than 40%. The figure below shows (scaled) measurements.
