Abstract:
1. A system for grinding grain into particles, the system defining a grain path with an input for receiving grain to form a grain stream and an output stream for ground grain particles, the system comprising: a first grinding apparatus configured to grind grain in the grain stream moving along the grain path into grain particles, the first grinding apparatus having a first output; a sifting apparatus configured to receive ground grain particles from the first output of the first grinding apparatus and to remove grain particles having a size less than a threshold size from the grain path, the sifting apparatus diverting the ground grain particles less than the threshold size from the grain path to the output stream such that the ground grain particles of the output stream are not subjected to further grinding; a second grinding apparatus configured to grind grain exiting the sifting apparatus on the first diversion path by the first outlet, the second grinding apparatus having a second output in communication with the sifting apparatus such that ground grain particles exiting the second grinding apparatus through the second output are directed to the sifting apparatus.
