I apologize in advance for my ignorance. Why are the different kinds of wheat grains mixed in the first place?

  Because a field of wheat isn't uniform. The goal is to make all the wheat perfect, but nature foils that by spoiling some of the wheat with mold/fungi; other parts of the field may grow over soil that has a higher heavy metal content. As truckloads of this non-uniform wheat are processed, the machinery sorts the grains to get a mostly uniform end product, rejecting grains that fall outside of an acceptable threshold.
