The Mills of Early America American Heritage

The Mills of Early America American Heritage

The miller was America's first industrial inventor. He was builder, banker, businessman and host to the countryside. When highways were no wider than today's bridle paths, the first good roads were built to the mills. Where there was a mill site, there was a nucleus for a town. America had so many Millvilles, Milltowns, Milfords and other ...

An evaluation of Relo grinding media (RGM, Reuleaux tetrahedronshaped bodies) performance versus standard grinding media (balls) was made through a series of grinding tests, including a slight modification of the standard Bond test procedure. Standard Bond tests showed a reduction in the Bond ball mill work index (wi) of the mineral sample used in this study when using Relo grinding media.

The earliest reference to an English mill was in 762 CE, in a charter issued by Aethelbert. By 1086, The Domesday Book indicated that there were more than 5,000 mills used throughout England; it has been argued that the majority of these mills were the same as the Norse mill. Overshot wheels were turned by the weight and speed of water.
