Every stone burr mill we offer has the widest possible texture range; they can produce ultra fine or very fine flour, coarser flour, meal texture, cereal grind, and even cracked grain. The stone burrs in most modern small mills have a synthetic engineered composition for precision, uniformity, efficient grinding, and long burr life.
It spins so quickly that the grain''s impact with the teeth causes the kernels to break into increasingly smaller particles. In order to choose the best grain mill, you need to consider how and why you''ll want to use grain mills offer greater versatility of textures, for those who plan to use their mill to make both coarse and super fine flours, while others boast efficiency or durability.

Our Sharpening Stone Grit Chart After discussing the topic of grit coarseness and fineness we decided to come up with our own chart. Since one person''s "fine" and one manufacturers "fine" may mean something completely different we established a 1 to 10 grit chart with 1 being the most coarse and 10 being the most fine.
