More patterns, optimum design for refiner 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.
