Gaining Control of Your Former's Water Weight

摘要

A familiar scenario: moisture fluctuations downstream of the former, and as a result, problems in the press. What is the answer? Folding box board producer Mayr-Melnhof Karton [MM Karton) worked with Voith to find the solution for its recycled cartonboard mill in Neuss, Germany. Two OnQ FormingSens units and four PrintForm HR forming fabrics improved board quality on the mill's BM 5. In addition, installing these products allowed the required drive output in the forming section to be reduced by 13%. This alone represents a cost saving of 87,000 euros per year. Following a successful startup of the two OnQ FormingSens sensors upstream of the DuoFormer D and suction couch roll, and of the four PrintForm HR forming fabrics, MM Karton and Voith's forming specialists jointly carried out a series of tests, including adjusting the vacuum at various dewatering elements. The goal was to improve board quality and reduce drive power, while maintaining the dry content.
