Innovations in contaminant removal and automation

The ease of use for this equipment was what the mill really appreciated. I ensured everything was in place the day before start-up, and after two hours the unit was removing contaminants without any issues. In fact, it still is." - Michel Normadin, Product Manager, Screening, Valmet

South Eastern Canada

ContaminentsValmet emerged as the preferred supplier among competitors, thanks to the innovative features of the Protection Screen DX. Unlike traditional HD cleaners, the solution offers positive protection, compact installation,  and enhanced removal capabilities for contaminants such as heavy plastics and more. The implementation of Valmet Protection Screen DX proved transformative for the mill's operations, replacing the outdated HD cleaner with a comprehensive solution. The automatic purging feature minimized manual intervention for operators while ensuring continuous operation without overload risks. In addition, integrated alarms and real-time monitoring further empowered mill operators to maintain optimal process conditions. Upon startup, the equipment led to improved raw material efficiency, safety, and the protection of downstream equipment.

Despite being the first unit installed in region and within the corporation, the process proceeded smoothly, showcasing the reliability and performance of the equipment.

The implementation of Valmet Protection Screen DX at the Canadian pulp and paper mill exemplifies a successful collaboration between technology and industry expertise. By addressing critical challenges related to contamination management, Valmet's innovative solution not only enhanced operational efficiency but also set a benchmark for future installations within the corporation. Best of all, the lack of oversight means that operators can simply push a button and walk away, allowing for operators to focus on other projects.

Summary

Location Pulp mill in Southeastern Canada
Challenges The mill faced challenges with contamination which led to frequent disruptions and equipment failures despite the presence of two magnetic traps. Inefficient cleanout mechanisms allowed metal pieces, pebbles, wood, and heavy plastic contaminants to bypass filtration, exacerbating issues like refiner plate failures and primary breakdowns. Manual purging by operators was ineffective leading to overload problems.
