De Drie Waaien (English: The Three Breaches) is a tower mill in Afferden, Gelderland, Netherlands which was built in 1869 and is in working order.
[2] De Drie Waaien is what the Dutch describe as a "Ronde stellingmolen".
This drives the lantern pinion wallower (21 staves) at the top of the wooden upright shaft.
At the bottom of the upright shaft is the wooden great spur wheel, which has 56 cogs.
The great spur wheel drives a pair of 1.50 metres (4 ft 11 in) Cullen millstones and a pair of 1.50 metres (4 ft 11 in) French Burr millstones via lantern pinion stone nuts which have 20 staves each.
