The picker would wear a special corn hook that would help pick clean and picking clean was preferred. As for shelling the corn, husks made no difference to mechanical shellers as they shelled the corn from the cob and separated corn from cobs and husks. Hand shellers required clean corn. As for grinding, hammer mills would grind cobs and husks.

Shaft speed. The 2nd key design and operational aspect for a hammer mill is the rotation speed. As the milling principle is based on the energy of the impact, the higher the speed, the finer the product can be expected as the particles will hit the hammer at high speed, but also be sent against each other or against the screen at high speed.
