Abstract:
1. A grain crushing apparatus comprising: a first sidewall and a second sidewall spaced apart from one another a throat dimension in a first direction; a first support shaft and a second support shaft positioned transverse to the first sidewall and the second sidewall, the first support shaft and the second support shaft each configured to rotate about an axis of rotation and are positioned a spacing distance from one another in a second direction normal to the first direction; a first grain crushing roller and a second grain crushing roller, each of the grain crushing rollers comprising a root diameter, an outer diameter, and a plurality of teeth; and a roller carrier assembly that is selectively extendible from the first sidewall and the second sidewall in the first direction, the roller carrier assembly comprising a first mount plate and a second mount plate spaced apart from one another in the first direction, wherein the plurality of teeth extend a tooth height from the root diameter to the outer diameter, wherein the first grain crushing roller is selectively coupled to the first support shaft and the second grain crushing roller is selectively coupled to the second support shaft, wherein the first grain crushing roller and the second grain crushing roller are intermeshed with one another such the first grain crushing roller and the second grain crushing roller are maintained at positions spaced apart from one another in the second direction by an overlap distance less than the tooth height and wherein the first support shaft and the second support shaft extend through the first mount plate and the second mount plate and are rigidly spaced apart from one another in the second direction.
