Rancilio Rocky SD

The MD series offers a range of dosing grinders designed to optimize the grinding of every dose of espresso. The powerful motor allows grinding at a low speed, which prevents the bean from overheating to maintain its aroma and keep the flavor intact. Rancilio offers models with different capacities. Robust and reliable, the entire MD range offers excellent performance at a low cost.

MD Rocky has grinding burrs with a diameter of 1.9 inch (50 mm), guaranteeing a production of 5.5-7.7 lb/hour (2.5-3.5 kg/h). The dosage is 0.2 Oz (7 g), with a capacity for 10.5 Oz (300 g) of coffee beans. Semi-automatic version.

The New Rancilio Rocky is the most durable coffee bean grinder available in its price range. It is extremely well made and we highly recommend it for home use and light commercial use. It is a dosing grinder, which makes it especially suited for use with an espresso machine. Although, it would have no problem grinding fine or coarse enough for any type of coffee/espresso machine you might have. The forks that are designed to hold your espresso machine portafilter in place are removable so that you may use any receptacle you want to catch the coffee. The Rocky is the grinder of choice for the finicky home barista due to its quality of grind and durability. Please note that most grinders are tested at the manufacturer and coffee grounds may be found in the grinder as a result. All machines sold are new unless otherwise clearly stated. 

This stainless steel version has a stainless steel back panel and base with a heavy-duty black case aluminum frame. This commercial-quality construction is durable and designed to match your other Rancilio products.

The Rocky can be quickly and accurately adjusted using its 55 different grind settings. To make the adjustment you just push down on a release lever and turn the bean hopper. You can quickly and easily change from course to fine. It can grind your beans into a fine powder for Turkish coffee or espresso and even course enough for French press. With a Rocky the most particular barista will be able to fine-tune their extractions to perfection.

The Rocky’s motor is legendary. It is the same motor that Rancilio uses in the Commercial MD40 grinder. It has a high temperature overload switch to prevent possible damage if a stone gets caught in the burrs.
Like the motor the grinding burrs on the Rocky are the same ones that Rancilio uses in the commercial MD40 grinder. They are the flat plate style and 50mm in diameter that are even designed to handle a commercial load. To turn the grinder on and off you just have to flip the switch that is located on the lower left front corner.

Both the bean hopper and ground coffee container are made of tinted plastic that are designed to help keep your coffee fresh. They both have covers that also help seal in the freshness.  The Rocky is designed to dispense the ground coffee directly in to your espresso machine portafitler. After the coffee gets ground it drops in the ground coffee container. Then just pull the handle and it will dispense approximately 7 grams of coffee through a small hole in the front directly into your portafitler.
