Splicing safety, controls, quality and rear splice methods
Basic tips for good splices are presented, as well as an overview of splicing safety and two rear splice methods (under and over).
Two front splicing methods and safety precautions with each
Two efficient winder front splicing methods are presented. Front splicing is more dangerous than rear splicing, i.e. nip hazards. One person should supervise.
Off-machine coater splicing is affected by several parameters
Splicing efficiency on coaters averages about 98%. Variables that affect the splicing process include primary roll speed match, paster roll speed match, paster roll gap, paster roll pressure, paper caliper/hardness profiles, splice tape pattern and tail length.
Steam & condensate 2 - condensate, heat transfer and maintenance
In the second of a two part series, we explain condensate behavior and heat transfer, as well as how syphons are used for condensate removal. We also list the most important maintenance checkpoints for air, steam and condensate systems.
Burning NCGs in recovery boilers makes pulp mills odorless
NCG (non-condensable gases) are composed of mostly sulfur gases and methanol. In large concentrations they can be toxic. NCGs can be collected and disposed of using the recovery boiler in a safe and reliable way.
Understanding coating viscosity, rheograms and rheology problems
Coating rheology is measured with low shear and high shear viscosity instruments. In coating rheology, viscosity is the measure of the resistance of a coating formulation to an imposed flow.
Valmet Online Learning - reduce your mill's knowledge gap
The current workforce is growing older, with many retiring within three to five years. The new workforce lacks fundamental skills and knowledge. Valmet's online training portal is an affordable alternative to bridge that knowledge gap.
Press fabric monitoring explains machine operating performance
Good press felt monitoring and conditioning methods help avoid runnability and quality problems. There is no single approach - but some of the best practices are described in this article.
Power and heating plant training increase profitability
Valmet offers training tools to cover all aspects of the plant, ranging from classroom style to web-based E-learning, with solutions tailor-made for your mill.
Web handling, construction & proper setup of bowed roll spreaders
Bowed spreader rolls are the most commonly used spreader roll and are critical to most web handling processes. Learn how the construction, web orientation, cover material and wrap angles play important parts in web handling.
