Through the proven refining legacies of Valmet, GL&V and J&L Fiber Services, Valmet offers the paper and board 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.
Let us be your co-driver for success. Our refining experts work in close cooperation with you to design and produce segments that are tailored to your individual needs. They understand your refining goals and the many related process variables that are critical to achieving success.
You can optimize the low consistency refining operations by
Pro safe segments 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 Low Consistency Refiner Segments give customers the flexibility to customize their approach to fiber processing to achieve specific goals in refining performance.
Valmet offers a wide range of patterns/features to low consistency fillings and segments for all existing LC refiners on the market.
| Alternating deep groove | Maximize groove width for less plugging. Achieve maximum hydraulic capacity, KM/Rev and increased wear resistance for longer life. |
| Attack bar |
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. |
