Impact mill

Apparatus for impacting a granular material, such as grains, seeds, comprising

• housing means having a distribution head mounted therein for rotation about a longitudinal axis;
• said distribution head having wall means forming at least one radially extending channel;
• drive means for rotating said distribution head;
• a ring-shaped impact member surrounding said distribution head and having a central axis;
• supply means arranged for supplying said granular material to said distribution head within a central region of the distribution head located at said longitudinal axis, so that the granular material being under the action of centrifugal force enters said at least one channel to be impacted against said impact member, said impact member being spaced apart from said supply means allowing said supply means to remain stationary independent of rotation of said impact member;
• rotating means for rotating said impact member around the central axis of said impact member and around said distribution head;
• wherein the longitudinal axis of said distribution head and said central axis of said impact member form an angle with each other;
• wherein said housing means further comprises
• lid means being movable between an open position and a closed position for enabling access to said distribution head, said lid means being arranged at the top side of the housing means;
• and
• bearing means for rotatably supporting said impact member on said lid means wherein said supply means comprises tubing means passing through an opening in said lid means, said opening being larger in diameter than said tubing means to permit a pivoting of said lid means while said tubing means is stationary;
• and
• wherein passages are provided by said at least one clearance above said impact member for discharge of said granular material, there being a space bypassing said bearing means between said annular wall of said impact member and said lid means for receiving granular material discharged via said passages.
