De Lelie is stage mill with an a stone base and a octagonal upper part. This means that the sails do not reach to the ground but can be reached from a stage or gallery. The mill is build on a square brick base with dimentions 6.3 m x 6.3 m and a height of 0.4 m. On the brick base stands the upper part, which starts with an square shape and end in an octagonal shape. The stage is on a height of 6,0m above the ground. On the upper part a rotating cap is placed, the windshaft is placed in the cap. The upper part and the cap are covered with reed.
The sails are of the common sail type. The welded steel stocks are manufactured by Bremer from Adorp en were made in 1969. The sail span of De Ster is 17,8 m. The cast iron windshaft is of unknown manufacturing. The mill has a Flemish brake consisting of four pieces and is operated with a lever. The cap rotates on a bearing consisting of 25 steel rolls and the cap is rotated with a windlass.
The mill is equipped with:
- A pair of edge runners for grinding of spices
- Five vats with each four stamps with knifes for grinding of snuff tobacco
- The remainings of two pair of spice stones
Edge runners
The edge runners are located in separate extension of the mill and is driven by the camshaft. The camshaft rotates just above the first floor and also drives the stamps. The edge runners consist of two ashlar runners which rotate on a cast iron platform. The runners have a diameter of 1,25m and a thickness of 28cm. Each runner has a weight of 0,8 metric tons. The gear ratio between the windshaft and the edge runners is 1:0,49. This means that the speed of the edgerunners is normally between 7 and 9 rounds per minute.
Vats
The stamps and the vats are driven by the camshaft. The camshaft is driven by means of a long axis by the windshaft. For each stamp three cams are mounted on the camshaft such that on one revolution of the camshaft each stamp is lifted three times. On each stamp are two knives mounted that cuts the snuff tobacco. The gearratio between the camshaft and the windshaft is 1:0,64. In this way, each minute between 110 and 150 times a stamp is lifted and dropped into the vat.
Pairs of spice stones
On the stage floor the spur wheel remains from the pair of spice stones that were located on this floor in the past. On the floor above the stage the sack hoist is mounted.
