The title says commercial while the marketplace application taxonomy also includes household, vehicle and outdoor contexts. Only package gross weight is exposed; it is not treated as machine net weight.

There are discrepancies in the listingA listing field says Grinding capacity of espresso coffee: 800 KG without a time basis or test definition; it was not used as throughput. The dimension value has no unit in the retrieved structured attribute, so no unit was inferred.
There are discrepancies in the listingThe title uses the market term DF64 although the listing identifies model YS-026 with a 60 mm conical burr; no 64 mm burr is claimed in the structured attributes.

The commercial title is accompanied by a broad application taxonomy that includes household, car and RV.

There are discrepancies in the listingStructured attributes say stainless-steel burr material, while the supplier detail says titanium. The material is not normalized. The page labels the model A85 but the supplier description calls the grinder an upgrade from 64 mm to 74 mm; 74 mm is retained as the current stated burr diameter. 14.4–14.5 kg is shown as gross/package weight, so product net weight remains null.
Does Burrs Diameter Determine the Quality of Espresso?+
No. That's one of the parameters. The geometry, the alignment, the revs, the state of the burrs and the tuning of the particular model also influence the outcome.
Is it possible to choose a coffee grinder only by grams per second?+
Clarify the fraction and method of measurement, then check the series of doses, heating, retention and adjustment.
When do you need a second coffee grinder?+
For the second grade, decaf, flow sharing, or reserve, the solution depends on the menu and peak workflow.
Link grinding to real workflow
Match the product, peak series, cleaning and the next step before choosing a specific model.
