Pulp Beating/Refining Methods TRIZ Cases
- Refiner Blade Segment Geometry for Stable Flow and Low Vibration
Angled side edges in refiner blade segments stabilize fibrous-material flow paths and reduce pulse-driven vibration during refining.
- Refiner Bar Height Zoning for Wood Fiber Bundle Breakup
Varying refiner bar heights combine fiber refining and bundle breakup in one stage, reducing clogging and separate deflaking steps.
- Optical Reject Stream Monitoring for Fiber Loss Control
Optical imaging of reject streams measures fiber content, discharge rate, and material type to cut usable fiber loss and waste in pulp processing.
- Dual-Gap Rotor Refining for Raw Material Entry and Defibration
A larger first blade gap and tighter second gap let raw material enter smoothly, then shear effectively for better defibration and discharge.
- Stepped Refiner Bar Coatings for Wear and Hydraulic Capacity
Variable coating thickness protects high-wear refiner bar surfaces while preserving hydraulic capacity and lowering replacement cost.
- Two-Stage Rotor Refining Structure for Complete Pulverization
A partitioned two-stage rotor lets larger feed enter first, then refines it between blades and liner for more complete pulverization.
- Refiner Blade Segment With Zigzag Edges for Stable Flow
Zigzag side edges form slit-like openings that stabilize refiner flow and reduce vibrations caused by changing rotor-stator incidence angles.
- Refiner Plate Segment with Wear-Compensating Radial Channels
Radial channels help refiner plate segments retain grinding performance as wear progresses.
- Variable-Height Refiner Bars for Wood Fiber Deflaking
Varying bar heights combine wood fiber refining and deflaking, reducing bundles, downstream clogging, and extra processing.
- Discharge End Wall Inserts for Mill Wear Mitigation
Segmented wear-resistant inserts replace only damaged areas, extending service life and reducing downtime.
- Single-disc Refiner Zone Segmentation for Energy Reduction
Segmenting refining surfaces into dedicated feed and treatment zones reduces energy consumption by 40% while maintaining pulp mechanical properties.
- Disperser Teeth with Truncated Pyramid Elevations
Treatment tools feature truncated pyramid elevations extending beyond the tooth base to create additional working edges for mechanical processing.
- Biomass Refining Steam Recycle Path Reduces Impurity Release
Recycling steam from the refining zone to the presteaming bin reduces fresh steam consumption and minimizes impurities released into the atmosphere.
- Locknut Covering Part for Disc Refiner Oil Leakage
A covering part shields rotating locknut notches, stopping the paddle effect that agitates oil and causes shaft housing leakage.
- Pinned Fly Ring Segments Eliminate Welding
Laser cut ring segments join via lapped joints and custom fasteners, eliminating welding and machining to maintain tight tolerances.
- Refiner Plate Bar Design for Stress Reduction
Segmented refiner plate bars combine narrow upper sections with wide lower roots to enhance structural strength.
- Medium Consistency Refining Pulp Process Energy Reduction
A thermomechanical pulping method sequences high and medium consistency refining stages to dilute pulp for efficient fiber development.
- Variable Height Refiner Bars for Pulp Deflaking
Varying refiner bar heights combine refining and deflaking functions in one unit, eliminating the need for separate processing stages.
- Refiner Control via No-Load Power Tracking
Tracking idle power over tool life prevents energy waste and damage.
- Refining Segment Backside Recirculation for Pressure Control
Backside support projections channel fibrous material through a dedicated space, preventing accumulation and stabilizing pressure in series-connected refiners.
- Curved Bar Refiner Plate for Counter-Rotating Mechanical Pulping
A refiner plate with curved bars and serrated edges increases wood chip retention time in the peripheral zone to improve energy efficiency.
- Refiner Plate Asymmetric Bar Radial Positioning
Varying radial distances of grinding bars generate turbulence that improves fiber entry and reduces clogging in pulp refiners.
- Single Refiner With Multiple Zones For Lignocellulose Fibre Refining
A single refiner uses multiple refining zones to process lignocellulose fibre material fractions simultaneously with tailored surface characteristics.
- Interlaced Blade Bars Prevent Buckling in Refiner Segments
Interlaced blade bars prevent buckling at feed grooves and sustain consistent cutting-edge length for reliable fibrous material refinement.
- Refiner Blade Segment Side Edge Openings Casting
Moving blade segment openings from the middle section to side edges improves casting ease while increasing rigidity.
