Through the proven refining legacies of Valmet, GL&V and J&L Fiber Services, Valmet offers the industry’s widest, most trusted portfolio of patented and customized refiner segments for low consistency refining. Reach energy savings, shive reductions, freeness improvement, longer segment lifetime and more with Valmet Refiner Segments.
The key to a successful operation is to have segments customized for fiber dimensions. Our refining experts work in close cooperation with customers to design and produce segments that are tailored to their individual needs.
Valmet offers segment solutions for both hardwood (short fiber) and softwood (long fiber) applications.
To achieve optimal results, different refiner applications require different designs as system optimization is undertaken. With the right expertise our customers can optimize their low consistency refining operations by:
We can offer you low consistency fillings and segments for all existing LC refiners on the market. Valmet Refiner Segments offer a wide range of patterns and features for all refining needs.
|Alternating deep groove||Maximize groove width for less plugging. Achieve maximum hydraulic capacity, KM/Rev and increased wear resistance for longer life.|
||Tilted bars towards the direction of rotation for more sustainable bar leading edges.|
|Constant angle||Refine with a pattern that features bars positioned at a constant angle from the center circle of the segment.|
|Equal flow||Control shive content without sacrificing the strength properties of the pulp in mechanical pulping processes.|
|Maximum flow||Pumping inlet bars for increased hydraulic capacity.|
|Micro bar||Achieve optimal refining performance in applications requiring significantly denser designs mainly for hardwood and mixed pulp applications.|
|Milled bar||Refine with a pattern featuring precisely machined bars and grooves; particularly for low intensity refining of bleached hardwoods.|
|Parallel bar||Refine with a pattern that features bars positioned parallel to one another across all segment fields.|
|Pro safe||Lighter and safer than conventional segments. Weighing approximately 75% less than traditional alternatives, Pro safe segments are safer and easier to position while bolting to a mounting surface.|
|Reverse flare groove||Prevent plugging with grooves that widen from ID to OD.|
|Turbulence dams||Improve fiber treatment with better fiber-to-blade contact with a pattern that features subsurface Venturi dams in the grooves of the ID zone.|
|Ultra low intensity||Maximize fiber strength development with a segment featuring virtually zero bar draft (0.5 degree) and a large open groove for longer life.|
|Variable groove||Improve performance with a pattern that forces pulp into the disk gap.|
Pro safe segments are one example of Valmet innovations for improved safety and performance. They are easy to lift and positioned for easy, user-friendly mounting. Designed to minimize risk and prevent injuries to the user’s knuckles, hands or back, Pro safe cast segments weigh 75% less than traditional, full-size segments.
Valmet invests in a positive safety culture, constantly improving its products and practices towards the company’s common goal of zero harm to people and environment. One of the latest safety-driven innovations is Valmet Refiner Segments - Pro Safe.
