Valmet supplied BM10 succesfully started-up at Liansheng Paper Longhai site
Oct 3, 2021
In the fall of 2020, during the Covid-19 pandemic, Liansheng Paper started up successfully and smoothly their Valmet-supplied BM10 board making line at their Longhai site. Since the start-up BM10 has been running stabily and is producing 125–230 g/m2 white top kraft liner. The whole production line has achieved very low levels of water, electricity, and gas consumption for the industry.
Despite the 100 percent domestic OCC with poor fiber quality we’re currently using, BM10 makes up for the disadvantage of the raw material due to the special design of its press section, enabling us to maintain the efficient high-speed production of lightweight products.
With the hood’s outstanding energy-saving effect, BM10 is superior to other machines in terms of steam consumption. The sizer also performs well, with precise sizing control, a wide adjustment range, high controllability, and a long-life sizing rod. The reel runs more smoothly than its predecessors and has a high turn-up efficiency, which improves our productivity.
The winder is amazing! It’s the first time Liansheng has attempted to match a paper machine with only one winder, and the result is better than expected. The automatic set change saves labor and enhances efficiency.”
