 — 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.

Step 5: Wet Grinding (and Recirculation) In this step, the liquid slurry with dispersed solids is circulated in the media mill along with the grinding media until the final particle size, or grind gauge, and surface characteristics are achieved. This can require multiple passes and speed adjustments in the hands of an expert equipment operator.

Grinding Mills. Barry A. Wills, James A. Finch FRSC, FCIM, P.Eng., in Wills' Mineral Processing Technology (Eighth Edition), 2016 Grinding is the last stage in the comminution process where particles are reduced in size by a combination of impact and abrasion, either dry, or more commonly, in suspension in water.
