Single dosing on the Gemilai CRM9009

The CRM9009 uses a 60 mm stainless steel flat burr driven by a 180 W motor, in a compact body measuring roughly 218 × 122 × 312 mm. The same grinder is sold under the Akira and 600N names in some markets. Its bean hopper holds around 120 g.

Worth being straight about that number: 120 g is already small — roughly six espresso doses. So unlike a grinder with a 1.5 kg hopper, you are not buying this to shrink a bulk container.

What you are actually buying

Two things. First, a hopper you can load with one weighed dose, so the beans in the machine are only ever the beans you are about to grind — no six-dose remainder going stale, no emptying before you switch coffee.

Second, the silicone bellows. A 60 mm burr chamber still holds grounds between doses, and on a compact grinder feeding small doses that carry-over is a meaningful proportion of what lands in the basket. Pressing the bellows after each grind pushes it out.

Version 3

Every unit we ship today is Version 3. The bellows is a custom branded, factory moulded silicone part — it is no longer 3D printed, as our earlier versions were.

How it is made

• 3D printed: lid, lid lock ring, connector, air-leak prevention gasket
• Factory machine moulded: silicone bellows

Materials

• Lid, lock ring, connector: PETG hard plastic
• Air-leak prevention gasket: TPU — material info
• Bellows: factory moulded silicone

Fitting

This hopper is made for the grinder named on this page. Fit tolerances vary between units and production runs, so minor adjustment may be needed to seat it perfectly on your grinder. Every unit is covered by our 2 year warranty.
