The PrimeLineCOMPACT tissue machine has a design speed of 1,900 m/min and a paper width of 2.8 m. A PrimePress XT Evo shoe press installed there dewaters the web gently, but still achieves a far higher post-press dryness than conventional presses. The 16 ft. PrimeDry Steel Yankee is made entirely of steel, having an evaporation rate that is 10-15% higher than that of cast iron models, which results in 8-10% better machine performance.
This combination – the latest shoe press technology and a steel Yankee – leads to a high drying capacity and achieves remarkable cost savings and operational flexibility as well as improved product quality. The entire line is equipped with an ANDRITZ PrimeControl automation package, providing an optimized production process.
In addition, ANDRITZ supplied the stock preparation system with two lines in order to process both short-fiber and long-fiber pulp, with the option of adding recycled fiber. The lines also have an approach flow system and a dissolved air flotation (DAF) unit for fiber recovery. The water system installed is designed to minimize water consumption, thus ensuring highest efficiency and sustainable operation.
The line was started up successfully under very challenging conditions due to the Covid pandemic. A key part of this success is thanks to Metris – the ANDRITZ digitalization platform – which ensures maximum mill performance at Berli Jucker Cellox, Prachinburi. In these challenging times with their travel restrictions, Metris effectively reduced personal contact by making use of remote functionalities. Remote assistance by ANDRITZ specialists enabled a straightforward commissioning-to-start-up phase and, in addition, ensures constant optimization of production processes, operator troubleshooting and decision support.
“I can remember when we first started talking about commissioning during the pandemic and, to be honest, we both felt some uncertainty given the challenging circumstances,” explains Tine Kocbek, ANDRITZ Project Manager for Tissue. Apinan Laocharoensuk, Managing Director of Berli Jucker Cellox Ltd., adds: “It took a lot of courage from both sides and also mutual trust to agree on such an arrangement. We really appreciated the excellent teamwork by the ANDRITZ colleagues from Europe and China. Today, we can confirm, it was the right decision!“
