SUBSTANCE: invention pertains to devices for dosing granular materials, inclined to arching, and can be used in the food, construction, pharmaceutical, chemical and other industries. The sluice feeder consists of a storage tower, a case with feeding and unloading connection pipes, mounted inside the case on a hollow bored shaft of a rotor wheel with blades. There are holes on the wall of the shaft, linked to the cavity of the shaft and the compartments of the rotor. There are detachable nozzles installed on the openings of the shaft with provision for rotation through a threaded joint. Openings in the nozzles are located at an angle to the axis of the nozzles. On the lateral surface the nozzle, openings are located along the perimeter.
