Automatic Domestic Flour Mill

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.When the upper circular stone rolls on the lower circular stones, it exerts pressure and force on the lower stone and the grains are placed in between them. Due to this force, the grains are crushed. However, these kinds of flour mills are manually operated and usually take a lot of time and energy.
