Top quality from the very start
Bohui Paper very contented with BM 3
2014-05-20 - Every paper manufacturer wishes that its new system will achieve good performance after a successful startup. This happened exactly when Bohui Paper’s BM 3 was commissioned. The board machine’s starting curve and efficiency were very good from the beginning. In addition, the product, a quadruple-coated ivory board, conquered the market within a short time.
Production on the BM 3 began last year and launched a new chapter in the history of paper and board manufacturer Bohui Paper. Although it is a long-established company from the Chinese province of Shandong, the BM 3 was the first machine going into operation at its Dafeng site in Jiangsu Province, where the company plans to install other board machines. One year after commissioning the paper manufacturer is very contented with the performance of the BM 3 as Huang Ju, Vice President at Bohui Paper, confirms: “After a very fast start-up, we have soon been producing paper of perfect quality. We are very happy to work with Voith, a partner with large technological experience and know-how.”
Proven components, modern technology. With a wire width of 8,750 mm and a total length of 400m, the BM 3 is one of the most efficient board machines ever. It is designed for an annual production of 750,000 metric tons of quadruple-coated ivory board in the basis weight range of 290–340 g/m2. The machine components for the complete production line were supplied by Voith, as were the entire automation technology and the first clothing.
The BM 3 features three Master Jet III-F headboxes and a three-layer wire section with a latest generation DuoFormer D. On the wire section’s intermediate ply a DuoShake ensures optimum fiber orientation and higher strength values. The press section consists of a double felted Tandem NipcoFlex press for a maximum line load of 800 kN/m. A steam blower box is installed upstream of the second nip for moisture cross profile control. An offset press ensures the high surface quality necessary, while surface smoothness is achieved by an EcoCal Hardnip calender with nozzle-type moisturizer and a heated roll with FlexiTherm coil. The coater consists of four DynaCoat AT coating units that use JetFlow free-jet applicators for non-contacting application of the two preliminary coats, the rear and top coats. At the end of the production line a Sirius roller with EcoChange reel changing system rolls up the ivory board for downstream processing by two VariFlex winders.//
