The Romans utilized vertical mill wheels very early on. This type of mill involved a vertical water wheel attached to a horizontal drive shaft. Pinion gears were used to transfer power to the upper millstones, changing the direction of the drive 90 °. This type of mill design is still utilized by most water-powered mills.احصل على السعر
