1. The Evolution of the Incorporating Process Marker
These buildings have been restored to their condition in 1885. They represent the highest level of development of roll mills and are, except for the source of power, identical to those in production throughout the world today. Many other methods of incorporating have been and are tried, but none has produced power as high quality as does this form of roll mill.
Earlier incorporating mills employed mortars and pestles. In 1839, the last of the "stamp" mills in the Hagley Yard was replaced by a roll mill.
