Jan 12, 2022

The delivery of Valmet IQ Web Inspection System for dirt count to Stora Enso Sunila Mill consists of an industrial camera system and a matching light source to capture crystal clear images of defects in the sheet. Located on the pulp drying machine after the drying section, utilization of the system gives the mill efficient and continuous online quality control.

Valmet IQ Dirt Count System
The results reached with the traditional dirt count method on a light table and the Valmet's Web Inspection System correlate well. Additionally, we now have access to real-time dirt count data in the control room without any delay, and this helps us to control our process faster and more precisely than before.
