Mazzer Robur S Automatic 3.5 lbs Doser Espresso Grinder, 500 RPM, Matt Black

The Mazzer Robur S is a commercial espresso grinder designed for high-volume coffee service in restaurants, cafes, and specialty coffee bars. Built from aluminum die casting and finished in black, this doser-style grinder draws on Mazzer's manufacturing heritage in Venice to deliver consistent, repeatable grinding performance on the commercial kitchen counter.

At the core of the Robur S is a 71 mm conical burr set spinning at 500 RPM, paired with micrometric grind adjustment so baristas can dial in espresso extraction with fine-step precision. The single hopper holds up to 3.5 lb of whole beans, reducing the frequency of refills during a busy service. The doser mechanism dispenses ground coffee in measured doses, keeping workflow structured and consistent.

The automatic grinding feature activates every 12 doses via the Memory Track System, replenishing the doser chamber automatically so the grinder stays ready without constant manual intervention. The unit operates at 120V, 60 Hz, and draws 800 watts, making it compatible with standard commercial kitchen electrical circuits. Dimensions of 11.5" (D) x 9.25" (W) x 28.5" (H) and a weight of 62 lb give the Robur S a stable, upright footprint suited to counter or dedicated station placement.

Each unit ships with an aluminum tamper and a stainless steel tray. The Robur S carries ETL Listed, ETL Sanitation Listed, CE, VDE, GS, KC, EAC, RCM, and Espresso Italiano certifications, confirming compliance with multiple international safety and sanitation standards. It includes a 1-year warranty by the manufacturer.
