Discover how easy it is to mill your own grain. Sturdy rollers made from highly tempered steel have adjustable settings to obtain desired grain consistency anywhere from flakes to flour. A special screen separates the flour from the bran and a convenient brush is enclosed for easy cleaning. The grinder attaches easily to multiple surfaces with the supplied “C” clamp. And the hopper holds approximately 1 cup. Within minutes you can have freshly ground flour for all your baking needs.
