Shoe press belts
Valmet Black Belt is a unique shoe press belt made of high performance elastomer material reinforced with dimensionally stable synthetic yarns.
The belt is available in different reinforcing structures and surface options to fulfill the demands of every shoe press. Valmet Black Belt is wear, chemical and heat resistant which ensures long and trouble free running.
Valmet Black Belt H
- Valmet Black Belt H (high performance) is the newest member of Valmet’s belt family. With the H design you reach longer lifetime and constant dewatering. The belt features:
Better dewatering with decreased water absorption and less decrease in void volume
Minimized crack development
Partly transparent elastomer for exact control of the casting process and quality
Valmet Black Belt structures
Valmet Black Belt surface options
- Plain belt for shoe presses with no nip dewatering.
Discontinuous grooves (DG)
- Discontinues Grooves prevent water to flow backwards in the nip.
Semi grooved (SG)
- Semi-grooved belt for high water contents to add the void volume of the press felt. The water is absorbed out of the grooves by the felt. Target grades pulp and fluting.
- Grooved belt for fast paper machines
High density grooved (HD)
- High density grooves for marking prone positions.
Making the right choices to boost wet pressing efficiency
Wet pressing has an impact all the way from paper machine drying capacity and web runnability to end product properties. The secret of process efficiency often lies in making the right choices for the press section consumables.
The shoe press belt family is growing
Valmet has been producing shoe press belts for the global market since the mid-1990s. Today, Valmet Black Belts are known for their excellent material mix, long lifetime and good dewatering capability. To meet the demands of today’s paper production, Valmet has recently developed yet another belt type: Valmet Black Belt H.
Proven by tests: Valmet Black Belt has highest impact strength
The most important property of a shoe press belt, used in paper and board machines, is its toughness, in all probability. Tough material survives in even the hardest and fastest impact situations. In tests made at Tampere University of Technology, Valmet Black Belt showed the best impact resistance compared to other belt designs.
New Valmet Black Belt E shoe press belt
Valmet Black Belt E provides paper and board makers with lower shoe press belt costs per produced tonne thanks to its excellent dimensional stability, wear resistance and long running time.
Valmet’s 1,000th Black Belt: success at Palm
There are two good reasons to celebrate the Valmet Black Belt that ran on Papierfabrik Palm’s PM 6 from July 2013 to January 2014: First, it was the 1,000th delivery of this unique shoe press belt, and second, it ran for almost 200 days. Congratulations!
