Description
Single dosing on the Ditting 804
The 804 is Ditting’s shop grinder, sitting alongside the larger 807 in the same family — closely enough that Ditting sells a shared 804/807 Lab Sweet burr set. Its bean hopper holds around 500 g.
We have not quoted a burr diameter for the 804 here. The figure we can source with confidence is for the 807 Lab Sweet at 80 mm, and we are not going to assume your 804 matches it. If the exact diameter matters, Ditting’s own product documentation is the place to confirm it.
Why replace the hopper
The 804 was designed for retail bulk grinding, where beans are loaded and worked through. If you are using yours for cupping, QC or espresso at home, that is not how the day goes — you want one weighed dose, then a different coffee, then another.
This hopper takes the stock hopper’s place so each dose is loaded on its own. The silicone bellows lets you push grounds out of the chamber and chute after each grind rather than leaving them to carry into the next sample.
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.
