Sieving TRIZ Cases

Square openings and tangential discharge in a screening drum prevent blockages from fibrous materials, maintaining high separation throughput.

Sawtooth interlocks align nested U-sectioned segments to seal edges and prevent water leakage during placer mining operations.

Size classified fly ash undergoes exhaustive magnetic separation to remove iron oxide contaminants and produce high whiteness filler material.

Replacing welding with segmented screw fasteners prevents thermal distortion of end rings, preserving sieve opening precision and structural integrity.

A variable slope mechanism adjusts the gear case angle to maintain optimal oil distribution across three-shaft vibrating screens.

Decreasing mesh sizes on a vibrating sieve separate stones from mineral-rich excavated soil, creating a reusable substrate that reduces landfill waste.

Screening belts remove stones from excavated soil to prevent pipe damage while maintaining cathodic protection and productivity.

Flexible spikes and a yielding base prevent breakage when hard objects enter the waste paper sorting mechanism.

Embedding an RFID tag directly into the shaker screen frame prevents detachment from vibration and fluid exposure while optimizing separation efficiency.

Bent wire segments form traps that capture microchips from drilling fluids, enabling automated recovery without manual intervention.

Multi-layer sintered screen mesh with a rotor element resolves the trade-off between screening capacity and selectivity by generating controlled turbulence.

A negative pressure shale shaker integrates a vacuum pan and liquid mist separator to remove fluid from drill cuttings.
