KILN COMPRISING A PROTECTIVE SEGMENT AT THE KILN OUTLET

摘要

The invention relates to a kiln (10) for firing cement clinker, comprising: a tubular rotary drum (22), which can be rotated about its central axis, wherein the rotary drum (22) has a discharge end (24) at which the cement clinker leaves the kiln (10); a protective segment (38) attached at the discharge end (24), which has a wear surface (44) pointing outwards and a cooling surface (46) pointing inwards, wherein the kiln (10) has a cooling device (26) for generating a cooling air flow, which flows along the cooling surface (46) of the protective segment (38), wherein the cooling surface (46) has profile bodies (58) in the form of pins.
