Comparison of hard and soft bearing roll balancing methods
Hard bearing type balancers measure residual unbalance. Soft bearing type balancers use a stroboscope and pickups to measure vibration amplitude and direction.
Coated board reel control rebuild reduces waste, case study
A coated board mill reduced bottom waste at the reel and increased board quality, with a rebuild from pneumatic to hydraulic reel control.
Operational basics of Compaction Baffle Filters (webinar)
Producing chemical pulp requires several unit operations involving washing dissolved solids from the pulp. The CB Filter combines two operations in one machine.
Valmet reduces fabric change time with no creasing, a case study
A new fabric change system created through cooperation between mill personnel and Valmet improves work safety, significantly shortens fabric change time and increases production time.
Energy consumption minimization in LC refining (webinar)
Low-consistency refining uses a significant amount of a mill's electricity consumption, especially refining in paper/board grades based on virgin fibers.
Is it time to convert your boiler to gas for energy savings?
If your power or recovery boilers are older and running on oil or other fuel sources - converting to natural gas may be a wise decision. Valmet has rebuilt several boilers, resulting in a cleaner less costly operation.
Common pulp washing fundamentals – How and why do we wash pulp?
Washing of pulp is a critical unit operation in the fiberline. Although washer designs differ, each type functions to wash pulp using common fundamental principles.
High power generation from recovery boilers: What are the limits?
The energy efficiency of modern recovery boilers, such as Äänekoski, can be improved by introducing high power features. Particularly important are the effect of ash composition and ash treatment.
