In 2022, Asia Symbol Guangdong Paper (ASGD) started up their new PM 13 machine. The project took just 17 months and started up on schedule in March 2022. Just four months later it reached a speed of 1,610 m/min.
PM 13 exceeded 1,610 m/min early in July, and the time efficiency of PM 11/12 reached 99.6 percent early in June. All this is due to the project team’s work. ASGD’s team has great confidence in Valmet because of their full life cycle services, and this is also a very important reason for choosing Valmet – they have always offered us improvements. For example, we applied hard nip calendering technology to PM 12, which extended the rolls’ service life and also reduced the replacement frequency. So, we continued to use this in PM 13."
The delivery also included the fabrics for the whole machine, the Valmet DNA Automation System, the Valmet IQ Quality Control System, and the control valve and on-off valve system for the complete line.
Results
The start-up curve was excellent. PM 13 exceeded 1,610 m/min early in July 2022, and the time efficiency of PM 11/12 reached 99.6 percent early in June. Asia Symbol has increased output without increasing pollution, and have reduced water, electricity and gas consumption.
