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.
