Why Was Everyone Talking About This Machine at the GENMA Booth?

At Breakbulk Europe 2026, one piece of equipment at the GENMA stand drew non-stop attention — the 2nd-generation Alumina Pneumatic Ship Un-loader. Attendees kept stopping, pointing at an unassuming device on the pipeline, and asking, "What's that?"

The conversations that followed often lasted half an hour. So we've rounded up the five most frequently asked questions from the show floor. If you're a terminal operator dealing with tricky bulk materials like alumina, see if any of these resonate.

Question 1: Alumina is basically sandpaper. How do you handle the wear and tear?
Alumina powder flows everywhere, finds every gap, and worst of all — it grinds. Pipes, elbows, valves — replacing them gets old fast.
GENMA took a deep dive into the material's flow characteristics, wear mechanisms, and dust behavior. Then we integrated a proprietary intelligent wear-reduction device at critical conveying points. The principle is straightforward: reduce hard friction between material and pipe walls at high speed, while keeping friction heat within a safe range. In short — we don't make wear disappear, we make it "slow enough you can live with it."

Question 2: How do you separate the air from the solids without blanketing the terminal in dust?
Pneumatic unloaders use airflow to pull material up, but it's not just cargo coming through — there's a lot of dust-laden air. If separation fails, you've got two problems: dust escaping (hello, environmental violations) or fine material blowing away (hello, angry cargo owners).
GENMA's approach: fully enclosed conveying from suction nozzle through pipeline all the way to the separation tower. Inside that sealed system, specially designed separation mechanisms split the dust-laden airflow from the material particles. The terminal stays visibly clean.

Question 3: When waves kick up and the vessel is heaving, how does the unloader move with it?
When a bulk carrier is half-empty, swell can make the hull rise and fall by a meter or two. If the suction nozzle can't follow, it either hangs in the air missing material or slams into the hold floor.

GENMA fitted this unloader with an anti-surge device — the nozzle automatically follows the vessel's vertical movement, handling up to two meters of heave. The ship bobs, the nozzle tracks, the material keeps flowing. No hovering, no collisions.

Question 4: Can you speed up the clean-up stage? The last bit always takes forever.
Standard nozzles struggle when the material gets thin — vertical inlets just can't reach, and you end up wasting time, fuel, and patience.
GENMA designed a 3D fishtail clean-up nozzle. The inlet switches from vertical to horizontal, the suction width expands significantly, and paired with a slewing mechanism, it sweeps and sucks simultaneously. Dead zones shrink. Clean-up efficiency jumps considerably.

Question 5: What about maintaining pipes, elbows, and other wear parts?
Maintenance convenience is the thing everyone overlooks — and it directly impacts downtime.

The Alumina Pneumatic Ship Un-loader's boom can be fully lowered. Not partially disassembled — fully laid flat. Pipes, elbows, trolley assemblies all fully exposed, and maintenance crews can reach everything from ground level. That means no scheduling cranes, no waiting for access windows. Inspect anytime, repair anytime, minimum downtime.

This new-generation Alumina Pneumatic Ship Un-loader isn't just for alumina. Granular materials like grain, powdered materials like cement — it handles them all.
