Example equipment update analysis - rebuild/replace/add a winder?
When examining an older piece of equipment that does not meet today’s performance requirements, a mill must determine if it should be rebuilt or replaced.
Stop waste due to cockle wrinkles - avoid contributing factors
Cockle wrinkles, common on light weight paper machines, cause waste paper and rejected rolls resulting from downstream sheet breaks. They are influenced by basis weight variation and high drying temperatures.
Wet end tools for paper/board quality and strength (webinar)
An upcoming webinar describes how each component at the wet end of a paper machine can be operated to optimize the quality and the strength of specific grades.
Recovery boiler optimization - Reduction rate control, case study
A recovery boiler’s main control variables of reduction rate were studied and the performance of the Valmet Recovery Analyzer’s online reduction rate measurement was evaluated in real recovery boiler conditions at Stora Enso Veitsiluoto in Kemi, Finland.
Mill Safety - Lockout procedures save lives and equipment
Locking out power sources and drives is an important safety procedure. If not done, components can be started while personnel are out of the operator's sight.
Measuring winder capacity - calculation and interpretation
There are many reasons to increase winder capacity. Speed up / quality are easy to predict, however operational / maintenance related issues are more difficult.
Reel service case study - Faulty turnups and mechanical audit
A U.S. mill was having problems with faulty turnups. Valmet personnel arrived at the mill, performed a mechanical audit and made adjustments to fix the problem.
Maintenance-free with reliable lifetime of Valmet Clothing Guide Valve
Pindo Deli - Perawang Mill Blok 4 in Indonesia faced the challenge of high maintenance costs due to the short operational lifetimes of their conventional clothing guide valves. To address this, they implemented the Valmet Clothing Guide Valve. This solution resulted in lower costs with interchangeable spare units, less maintenance with common functionality, reduced wear on machine clothing, and minimized failure risk.
Reliable results through pilot trials at Valmet Fiber Technology Center
Valmet Fiber Technology Center in Inkeroinen, Finland provides complete pilot processes for stock preparation, recycled fiber, mechanical pulping and pulp drying - driven by innovation and evolving raw materials. This world-class facility has conducted more than 10,000 pilot trials since it first opened, helping paper makers improve efficiency and competitiveness.
Pioneering new air drying technology at Zhejiang Forest United Paper PM 6
To close a gap in its production capacity, Zhejiang Forest United Paper invested in a new PM 6 board machine. Among other Valmet-supplied key technologies, the delivery included an OptiDry Coat double-pass air dryer - the world’s first installation of its kind.
