Abstract (en)
[origin: ES8304657A1] A device for sealing the gap between the inlet end of a rotary kiln and a stationary inlet housing. In this device a ring which is capable of sliding in the axial direction is supported on a stationary ring by at least one first annular sealing element, and the sliding ring has on its end facing the rotary kiln a first wearing surface which co-operates with a second wearing surface on a rotating ring fixed on the inlet end of the rotary kiln. Cylinders operated by a pressure medium urge the sliding ring in a direction towards the inlet end of the rotary kiln and hold the two wearing surfaces in close sealing contact with one another. To ensure that the sealing contact of the wearing surfaces can be maintained even with relatively long rotary kilns in all states (cold and hot), the sliding ring includes a plurality of ring elements which are concentric and telescopic. The inner ring element is supported by the first sealing element on the stationary ring while the outer ring element bearing the first wearing surface is supported by a second sealing element on the inner ring element.
