KILN INLET & OUTLET SEAL

Graphite seals are essential for reducing false air intake and allowing flexibility in a kiln's movements. They are held in place by a wire rope system, ensuring an efficient seal against the outer air casing. False air intake increases fuel consumption, production output decreases, and operating expenses increase. Graphite seals require no greasing and are maintenance-free under normal conditions. They provide effective leak tightness around the kiln discharge hood, improve pressure stability, allow installation on existing kilns without modifying the shell or inlet, absorb kiln expansion and slide range, and require no maintenance.

The kiln inlet seal is a flexible and secure sealing system that connects the kiln to the preheater. It features heat-resistant steel scoops to collect spillage and return it to the kiln. The smoke chamber suspends spillage, carrying it into the kiln riser pipe. The inlet seal provides 10,000-20000 service hours, while the outlet seal offers flexible sealing between the kiln and cooler. It consists of a non-rotating cylindrical ring of steel plates around the kiln on the kiln hood, supporting special steel that slides on the cooling mantle. A material return system is included on either the first grate or the external drag chain, collecting escaping dust and returning it to the cooler. The kiln outlet seal delivers 7,000-14,000 service hours, providing secure sealing, material return system, and long lifetime for wear parts.
