This is a "Grain Gobbler" mill, as sold by MoreBeer and Fermentap. At the heart of the mill are two 1.5" x 4" knurled rollers, which are adjustable through 10 pre-set positions for a uniform gap spacing. The rollers ride in bronze bushings and thus require no maintenance or lubrication. The mill includes the needed hardware to temporarily attach it to the top of a typical 6.5 gallon plastic fermenter pail, for ease of use. The included stainless steel hopper will hold up to 8 pounds of grain at a time. The mill itself is powered via a drill adaptor, and will handle about 4 pounds of grain per minute at 400 rpm. Sells new for $240. Yours for $150 plus shipping costs.
