Ditting / Bizerba KF902 shop grinder rebuilt - Home-Barista
Ditting stated those burrs have a life expectancy of 20.000 lbs at medium grind (well at 250€ per burr set one would expect no less) someone on HB quoted a Ditting person saying that the burrs are at its best after appr. 300-400 lbs (lowest fines production), but i think that was referring to the 80mm burrs of the 804/805/Tanzania
