Pugmill
From Wikipedia, the free encyclopedia
A pugmill or pug mill is a machine in which materials are simultaneously ground and mixed with a liquid. Applications can include the mixing of clay for pottery production, as well as industrial applications such as building materials and road paving: bricks, cement and some parts of the concrete and asphalt mixing processes.
According to the 1913 edition of Webster's Dictionary, a clay pug mill typically consists of an upright shaft armed with projecting knives, which is caused to revolve in a hollow cylinder, tub, or vat, in which the clay is placed.
The origin of the term is the verb to pug, meaning to mix and stir when wet.
