Paper Machine Upgrades
Engineer of Record for Paper Machine Upgrades at Newberg, OR Mill.
Due to declining newsprint demand, the client’s mill needed to transition to new grades where market demands were more robust. The challenge was to allow for this conversion with minimal capital investment.
The project required a lean approach to design and engineering from stock preparation to the paper machine and roll handling system design.
How We Did It
Harris Group worked with mill engineering and equipment vendors to develop an OCC recycling system design utilizing many existing mill assets by re-purposing them for OCC production. For the screening and cleaning system, Harris Group provided 3D models enabling mill staff to view and have input into the final equipment and piping layout. Onsite field support was provided during the design and construction phase allowing the mill to achieve the projects budget and schedule requirements.
Harris Group served as design engineer for process, structural, mechanical and piping design for upgrades to the mill to allow production of packaging grades. This project installed the necessary upgrades to allow one of the two machines to be capable of producing packaging grades.
Harris Group leveraged state of the art tools and methods to allow best practices to be utilized for delivery of this project.
For the roll handling system, Harris Groups structural team collaborated on different structural solutions to address the removal of major building structural elements.
The team was able to develop simple and cost-effective design solutions that enabled the new system to be installed within the mills capital budget restraints.
Other project elements included: New 500 TPD OCC system, Paper machine white water segregation, Paper machine stock prep modifications, low consistency refining, forming section upgrades, PM steam and condensate system upgrades, New roll handling system.
