Description

De Bullemolen is what the Dutch describe as a Grondzeiler. It is a three storey smock mill on a single storey base. There is no stage, the sails reaching almost to ground level. The mill is winded by tailpole and winch. The smock and cap are thatched. The sails are Common sails, with one pair having leading edges on the Fauël system. They have a span of 20.5 metre. The sails are carried on a cast iron windshaft. which was cast by Fabrikaat L Enthoven en Compagnië in 1882. The windshaft also carries the brake wheel which has 55 cogs. This drives the wallower (30 cogs) at the top of the upright shaft. At the bottom of the upright shaft the crown wheel, which has 40 cogs drives a gearwheel with 33 cogs on the axle of the Archimedes screw. The axle of the Archimedes screw is 580 millimetre diameter. The screw is 1.44 metre diameter and 4.82 metre long. It is inclined at 18°. Each revolution of the screw lifts 1130 litres (248.6 imp gal) of water.
