ANDRITZ successfully starts up OCC line at Wamat Paper, China
International technology Group ANDRITZ has successfully started up the first of two OCC lines, each with a capacity of 1,000 bdtm/d, supplied to Shandong Wamat Paper Co., Ltd., Shandong Province, China.
Start-up of the second OCC line is scheduled for the end of this year. Both lines produce pulp for corrugated medium as the final product.
The ANDRITZ scope comprises the entire equipment from pulping to headbox screening and includes a saveall disc filter for fiber recovery.
The equipment and technologies supplied by ANDRITZ enable excellent stock quality and yield significant savings in energy consumption. The lines feature the following technological highlights:
- Low-consistency (LC) pulping system, including a FibreSolve FSR pulper with flow-optimized rotor and vat for low power consumption, as well as a FibreGuard detrashing system with a FibreWash Drum in order to remove non-disintegrated rejects early in the process.
- Special coarse screening set-up combined with cleaners for light and heavy reject removal to provide superior stock quality and reliable separation of styrene foam. Fine screens and fractionators are equipped with innovative PrimeRotors to ensure highly efficient reduction of stickies and debris.
- The complete system is characterized by a special concept using a smaller number of pumps, resulting in significant reductions in energy consumption.
Mr. Zhang Yanjun, General Manager, Wamat Paper recalls: “Despite several difficulties relating to accommodation and transport as well as strictest health and safety precautions in view of the COVID-19 pandemic, ANDRITZ provided excellent start-up support and was first on site after the government permitted people from other provinces to enter our region again.”
Wamat Paper and ANDRITZ (China) Ltd. have once more demonstrated their excellent cooperation and completed this successful start-up even in the most challenging crisis situation.
Shandong Wamat Paper was established in 2017 and is a subsidiary of the Shandong Century Sunshine Paper Group Co., Ltd. – an important player in the Chinese but also the global papermaking industry.
