A mill is a facility for grinding or crushing. The term usually refers to a grist mill, for grinding grain into flour: it consists of one or more large circular stones (“millstones”), mounted on an axle, and turned by wind, water, or animals. The mill is a period charge, found in the canting arms (German Mühle, “mill”) of von Uhrmuhl, 1605 [Siebmacher 98]. In this form, the axle is vertical, with a balancing beam on top. For related charges, see grindstone. See also windmill.
