— Grist for one's mill ~ Since wheat and corn are ground by 'teeth,' the grinding stones 'chew' the grist into flour; thus to 'chew' over something became a thought or idea to ponder. The daily grind ~ The repetitive nature of milling led to the concept of 'the daily (same old) grind.' Run of the mill ~ The ordinary, daily grind.
— As the mills tumble and turn the grinding media wears away until the mill charge is too low to maintain the grind. The solution to this problem is to add more media. In the case of the rod mill the circuit will have to be shut down to accomplish this, the ball mill, however may have its media added while it is running.
