Key considerations Burr vs. impact mills. Grain mills all employ some mechanism to grind, crush, or shred the grain. You can choose from three main mechanism types: stone burrs, metal burrs, and impact mills. Traditional milling mechanisms employ burr grinders, in which two plates grind the grain.

A larger volume of removed material will require a bigger size of the burr's head. Select the tool r/min depending on the diameter of the burr head, the material to be ground and the material in the rotary burr. Use tungsten carbide burrs for hard and tough materials. High speed steel burs are recommended for unhardened and medium hard materials.
