Fibrous Raw Materials TRIZ Cases

A tapered backflow guide groove redirects shives and backward-flowing fibers into the refining gap to improve pulp quality without extra processing.

Concave grooves replace wear strips to keep an even rotor-screen gap, reducing wear and impurity entry while improving pulp screening throughput.

Sequential compression and mechanical modification sections target nozzle clogging, energy use, and uneven fibre treatment.

This case adapts fibrous suspension and rinse-water inflow, plus cycle duration, to rotor power and changing contaminant loads.

Dry refining with chemical additives separates polyethylene from paper fibers, preventing micro-plastic pollution while producing recyclable insulation.

Counter-rotating rotors apply shear and impact forces to fibrillate cellulose fibers, enabling single-pass industrial production without multiple refining runs.

Pre-compressing grass fibers before joint milling protects sensitive structures from breaking, maintaining fiber length while improving paper surface area.

Circumferential groove and radial channels in the center ring collect back-traveling steam, preventing interference with fibrous material processing.

A refiner segment uses border openings to guide back-streaming steam inward while retaining unprocessed material within refining zones.

Spaced rotary cutters with obtuse angles tear paper into small pieces, preserving long fibers to enhance recycled paper strength and reduce binder usage.

A mixer with rotating compression elements modifies cellulose fibers in aqueous suspension.

Angled dam geometry reduces flow restriction and blade wear, lowering energy consumption during lignocellulosic refining.

A central froth collection launder repositions overflow capture within large flotation cells to optimize surface area ratios.
