The Mazzer Kony Espresso Grinder with Doser is THE grinder to own for fast paced high volume espresso shops.
Why buy a Kony? The conical burr advantage!
63mm Conical Grinder Burrs.
Conical burr espresso grinder's motor spins at a much slower speed. Usually at about 500-700 RPM however on the Mazzer Kony the speeds are between 420-500 RPM. The advantage of slower grinder burr speeds means excessive heat won't be transfered from burr to beans preserving all the flavor, aroma, and integrity the coffee has to offer.
Conical burr grinders also produce a more consistent and precise grind which help produce the most flavorful espresso-based beverages. Espresso grinds consistent in shape and size assist the espresso machine with even extraction.
