A year of successful board production for Liansheng’s new line
C
hina’s Fujian Liansheng Paper Industry is celebrating a year of successful production
for its new BM8 board machine supplied by Voith at its Zhangzhou mill in Fujian Province. Xue Rongjun, vice general manager of Liansheng Paper, said when commenting on the stable and productive performance of the machine: “Voith’s vast technological experience, high system efficiency and low operating costs are quite attractive.” Planned daily production was
reached less than two months after start-up and continues to exceed expectations. With a 7,300mm wire width and 1,100 m/min design speed, the Liansheng BM8 produces white lined chipboard in a basis
weight range of 200 to 450 g/m² and coated White Top Testliner from 175 to 200 g/m². Yearly production is expected to reach 700,000 tons. Using Voith’s DF Coat curtain
coating technology, which enables virgin fibre to be replaced with secondary fibre for the coating layer, the BM8 can produce board and packaging paper grades from 100 per cent
secondary fibre. This will help to achieve Fujian Liansheng Industry’s aims for recycling, resource conservation and sustainable development. At the same time, Voith has improved production properties so that whiteness and optical properties can be optimized as required with a much smoother surface. Voith also delivered an
automation package including the Machine Control System (MCS) and the Quality Control System (QCS). Also included in the scope of supply after start-up were fabrics, services for training, and technological support. Founded in 2005, Fujian Liansheng Paper Industry Co annually produces 2 million tons of board and paper grades for the Chinese market.
Scanner improvements for Ahlstrom’s filter paper mill
A upgrade of the integrated control system and scanners at an Ahlstrom Filtration filter paper plant in the US is being provided by ABB, the Swiss- based power and automation technology group. The upgrade is intended to deal with downtime risk due to aging parts while delivering better health diagnostics with improved process management and control. However, planning for this upgrade was not as straightforward as the previous ones. Ahlstrom knew that one of

potentially resulting in extended machine downtime. “We asked ABB if there was
