A feed mill is shown for chopping and crushing grain, such as corn, for the production of animal feed or fodder. The feed mill has an input hopper defining a longitudinal outlet opening. An elongate rotatable cutter assembly is located in the hopper adjacent to the hopper outlet for chopping and feeding the grain therethrough. A pair of adjacent, parallel, rotatable crushing rolls defining a nip are located below the hopper outlet. The crushing rolls have cylindrical surfaces defining pyramid shape indentations arranged in a diamond pattern and surrounded by protuberant cutting edges. Drive means are coupled to the cutter assembly and the crushing rolls for rotating same. The crushing rolls are rotated in opposite directions so that grain from the hopper outlet enters the nip to be crushed and passed through the crushing rolls. A conveyor removes the crushed grain from below the crushing rolls. The crushing rolls include a driving roll, and a driven roll, the latter roll being driven by frictional contact between the adjacent surfaces of the respective rolls.
