A Closer Look at Vertical and Horizontal Milling Machines
In vertical mills, the spindle axis is vertically oriented. Milling cutters are held in the spindle and rotate on its axis. Typically the spindle can be extended, or the table raised or lowered to produce the same effect, allowing for plunge cuts and drilling. The two kinds of vertical mills are bed mills and turret mills.

Mill (grinding) - Wikipedia
Tower mill. Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a grinding process. Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to help grind ore, however these mills ...
Windmill - Wikipedia
A windmill is a structure that converts wind power into rotational energy by means of vanes called sails or blades, specifically to mill grain (), but the term is also extended to windpumps, wind turbines and other applications. Windmills were used throughout the high medieval and early modern periods; the horizontal or panemone windmill first appeared in Greater Iran during the 9th century ...
