Windmills and Their Technology since the Middle Ages
The first practical windmills were panemone windmills, using sails that rotated in a horizontal plane, around a vertical axis. Made of six to 12 sails covered in reed matting or cloth material, these windmills were used to grind grain or draw up water. [9] These windmills are recorded by Persian geographer Estakhri in the 9th century as being …
Tower mill and its application to fine grinding
Abstract. The Tower mill is a vertical stirred mill using steel balls or pebble grinding media. This device is designed for fine grinding at significant power savings when compared to conventional tumbling mills. This paper describes the machine and its operation, application, and performance for wet grinding.

The objective of the work is to simulate and scale-up the pilot vertical mill from parameters obtained in batch ball mill tests using small quantities of samples and simple laboratory equipment. 2.
(PDF) DESIGN AND FABRICATION OF VERTICAL AXIS WIND …
1.1 BACKGROUND Vertical axis windmills, such as the Savonius (built in 1930) use drag instead of lift. Drag is resistance to the wind, like a brick wall. The blades on vertical axis windmills are designed to give resistance to the wind and are as a result pushed by the wind. Windmills, both vertical and horizontal axis, have many uses.
