Abstract: A milling apparatus in which at least two independently driven axiaily mounted elements are eccentrically mounted one within the other so as to define a processing chamber (12) therebetween with the minimum radial gap between the elements at one position being diametrically opposite to the maximum radial gap. Stresses are applied to the material by passing it through the minimum radial gap, which is adjustable. The elements may be rotated in the same direction to apply compressive and extensional stresses to material within the minimum gap, or in opposite directions to apply shear stresses to the material within this gap. A third element may be incorporated within the chamber to provide heat transfer and distributive mixing to the stressed material.
