The English Medieval Windmill | History Today

In the earliest Middle Ages milling - where it was not done by hand using quern-stones ('blood-mills', as they were sometimes expressively called) - was performed using either water-power or horsepower. But from the late twelfth century in Europe a new source of power became available through the invention and rapid spread of the windmill. Dependent as they were on the vagaries of the wind ...

Stirred Milling Technology – A New Concept in Fine Grinding

Mill structure The vertical stirred media grinding mill uses a grinding chamber filled with small beads whereby comminution takes place by attrition between the beads. The stirring effect is caused by rotating discs mounted on a shaft. There are also stationary discs on the mill body positioned in .

Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
