Industrial Flour Mill Machine

A gristmill (also: grist mill, corn mill, flour mill, feed mill or feedmill) grinds cereal grain into flour and middlings. The term can refer to either the grinding mechanism or the building that holds it. Grist is grain that has been separated from its chaff in preparation for grinding.Grain is fed in at the center of the running stone, and the turning of the stone shears the grain without crushing it. Centrifugal force carries the cut grain, called meal, through chiseled grooves in the bed stone to the rim of the millstones, where it collected in a vat and funneled down to the basement.
