Granulation In Rotating Drums TRIZ Cases

A toothed scraper forms variable-height circumferential ridges that extend residence time and improve uniformity when balling metallurgical waste.

Separate sulfur and water flows control nozzle conditions for single-pass granulation, reducing screens and return conveyors.

Controlled particle size distribution and flow characteristics resolve edge portion filling insufficiency while eliminating material waste from overfilling.

Biochar aggregate particles form through starch binding and extrusion, resolving inconsistent particle size distribution from pyrolysis.

Selective extraction removes phytotoxic residuals from biochar, preserving carbon porosity while isolating soluble signaling compounds.

Water vapor heats granulated sintering raw material in a drum mixer to boost gas permeability.

Tumbling olive pit fragments creates rounded infill for artificial turf.

Segmented lifting flights elevate sulfur seeds into falling curtains that cool and enlarge particles without fan-driven air circulation.

Flash evaporation removes ethane-1,2-diol from unstable ester mixtures to produce stable crystalline flakes for cost-effective polyester reuse.

Movable first wall transitions between working and cleaning positions, resolving narrow hatch access constraints in granulating apparatus.

Circumferential ridges on a coated rotating tube increase friction and compaction, enabling faster fertiliser pellet production with controlled size.
