Abstract: A device for comminuting bulk material grains (K) having a first element, designed as a rotor having a cylindrical circumferential surface with a first surface (31) and a first receiving portion (41), and a second element designed as a shear strip (51) having a second surface (61) and a second receiving portion (71), and a supply unit. The first and the second surfaces (31, 61) lie parallel to and face one another. The first and second elements are relatively movable between first and second positions (P1, P2) in a plane of the first and the second surfaces (31, 61). In the first position (P1), the first and second receiving portion (41, 71) communicate with one another, via a passage (9) forming a receptacle, in which the bulk material grain (K) can be positioned, and, upon moving to the second position (P2), a cross section of the passage (9) is narrowed.

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.

Abstract: A chipping apparatus includes a housing arranged about an axis of rotation and a chipping system within the housing rotating in a predefined direction about an axis of rotation. The chipping system has chipping tools that form a circular or ring-shaped chipping zone. The housing is divided into the sectors I, II, III and IV in the direction of rotation, with a material outlet being arranged in sector I. The axis of rotation of the chipping system is arranged eccentrically, with respect to a central axis of the housing, in the region of sector I or II.

An upper conical element is disposed above the rotor and is free-wheeling relative to the bottom rotor, and thus rotates in response to rotation of the bottom rotor.

Vertical spacing between the two rotating members may be adjusted for varying the degree or extent of the reduction. The axes of rotation of the two members may be offset to provide additional G forces and a scrubbing action.
