ABSTRACT:
A cellular wheel sluice for the feeding of hot bulk material with stabilization of the radial play between the web ends of the cellular wheel and the wall of the housing borehole by means of the combination of materials of different thermal expansion coefficients, whereby for stabilization of the radial play between the walls of the cellular wheel and the case wall its changes of diameter caused by heat are compensated. End strips used for sealing the gap, in their radial expansion, are fixed in a retention body with a low thermal expansion coefficient and therefore are always kept at a temperature-independent constant external diameter from the cellular wheel shaft.
