Abstract: A cellular wheel sluice has a housing, a feed shaft opening therein and an outlet shaft opening out therefrom. Arranged between the shafts is a cellular wheel. The latter is arranged so as to be rotatably drivable about a horizontal rotational axis in a cylindrical cellular wheel housing portion. A cellular wheel drive shaft non-rotatably connected to the cellular wheel is rotatably mounted in the housing. A pressure drop is applied during operation of the cellular wheel sluice, a higher pressure being present in the feed shaft than in the outlet shaft. The cellular wheel is operated during the product conveyance between the feed shaft and the outlet shaft at a rotational speed in such a way that an outer periphery of the cellular wheel reaches a speed that is greater than 0.6 m/s.

Abstract: The assembly is so configured as to use common parts, whereby another assembly, having a different gear ratio, can be formed using the selfsame common parts. Only different gears, and a different frame is required to form the alternative assembly having the other gear ratio. Accordingly, stocking of discrete parts for the differing assemblies is greatly reduced.
