A Trusted Grinder

Trusted by cafés, roasteries, and retail stores across the world, the KR804 is the faithful flagship grinder of the Ditting line. At heart, the KR804 is a high-performance retail bag grinder optimized for a full range of grind sizes (from Turkish to cold brew), featuring a sturdy, spring-loaded bag clamp to hold coffee bags and vibrating steel shaker plate to settle the grounds as they fall. On the modified model, the vibration plate is replaced with a non-vibrating stationary plate designed to accommodate a range of receptacles, including single-dose grounds containers, bins, or bags.

The 804’s 80mm tool steel burrs (rated for 15,000 lbs.) are celebrated for producing cups of balance, clarity, and sweetness across the full grind range and are thus an improvement on many of the popular retail grinders on the market. The KR804 can easily handle the workload of specialty coffee shops, grinding for batch brewing, pour overs, and, due to its stepless adjustment, even espresso, but because of its attached plate, it is often used primarily to grind into retail bags for customers. The 804s are also incredibly speedy. The 500-watt motor rotates the burrs at 1650 RPM to grind an impressive 2lbs per minute at 800 microns, up to about 30 pounds per day, which is plenty enough for most cafés.

A Perfect Fit

For all its power and capabilities, the Ditting KR804 has a surprisingly compact, unassuming frame which is why it is the most ubiquitous grinder you may have never seen. It is just 19-inches high (a height that includes the built-in hopper), 8-inches wide, and 10.25-inches deep—and an equally surprising heft—50 pounds—, a weight doubtless attributable to the heavy metal components (all the way down to the retention knocker and fan blades) and very little plastic (only the lid and adjustment dial). Its dimensions and weight, in combination with its compact footprint, make the KR804 the perfect fit for nearly every commercial space, from the shallow or crowded countertops to those narrow windows between equipment. The KR804 is an easy addition to any café, retail setting or roastery.
