Nuova Simonelli MDJ Coffee Grinder

A Nuova Simonelli MDJ coffee grinder with a 1.6 kg bean hopper, grinding at 4 g/s on an 800 W motor at 230 V, weighing 15 kg. Output of 4 grams per second means an 18 g double dose takes about four and a half seconds — fast enough that the grinder never becomes the queue at a busy bar.

Who it suits

For busy cafes and hotel bars, particularly those already running Nuova Simonelli espresso machines and wanting a matched grinder. The 1.6 kg hopper is generous, so refills interrupt service less often than smaller grinders. Low-volume sites will not need this throughput and can choose something more compact.

Common questions

How fast is 4 g/s in practice?
An 18 g double dose takes roughly four and a half seconds, so dosing does not hold up the bar during a rush.

How much does the hopper hold?
1.6 kg, which is larger than most commercial grinders and means fewer refills through a service.

Does it need to match my espresso machine?
No, any grinder works with any machine. Matching brands is an aesthetic and service-support choice rather than a technical requirement.

Why does it list two power figures?
800 W at 230 V and 900 W at 115 V reflect different regional supplies. UAE installations use the 230 V figure.
