Abstract
A kiln for firing cement clinker may include a tubular rotary drum that can be rotated about its central axis. The tubular rotary drum may have a discharge end at which the cement clinker leaves the kiln. A protective segment may be attached at the discharge end and may have an outward-facing wear surface and an inward-facing cooling surface. The kiln may include a cooling device for generating a cooling air flow that flows along the inward-facing cooling surface of the protective segment. The inward-facing cooling surface can include profile bodies that are pin-shaped. The profile bodies may be uniformly spaced apart, parallel to one another, and/or present over 20% to 60% of the inward-facing cooling surface.
Claims13
A kiln for firing cement clinker, the kiln comprising:
- a tubular rotary drum that is rotatable about a central axis, wherein the tubular rotary drum includes a discharge end at which the cement clinker leaves the kiln;
- a protective segment that is attached at the discharge end and includes an outward-facing wear surface and an inward-facing cooling surface, wherein the inward-facing cooling surface includes profile bodies that are pin-shaped, and wherein the profile bodies are spaced apart such that a gap is formed between each two adjoining profile bodies;
- and
- a cooling device for generating a cooling air flow that flows along the inward-facing cooling surface of the protective segment.
