Kiln outlet graphite plates seal
THIS OUTLET SEAL CAN BE INSTALLED ON ANY ROTARY KILN EQUIPPED WITH A GRATE COOLER
Energy savings and production increase thanks to the graphite plates system which prevent false air entries
Advantages :
- Adjustable to any type and size of kilns
- Long lasting efficient leak tightness without any specific maintenance
- Prevents false air entries in the kiln
- Ensures pressure stability in the kiln
- Prevents release of hot gases and dust particles from the kiln
- The suppression of dust outside the kiln ensures a longer life time of the mechanical components (bearings, roller, etc.) located nearby
- Allows an increase of the throughput through the kiln
- Its installation requires only 10 days under our supervision
- The replacement of a graphite plate does not require a kiln shutdown
Principle :
- A specially designed circular bearing race (or sliding track) is mounted on the kiln and adjusted to compensate for any pre-existing eccentricity
- The graphite plates are mounted on a specific support (designed case by case) which is bolted on the kiln burning hood
- The graphite plates are held in contact with the circular bearing race with the help of 2 metal cables and adjustable counterweights
- Cooling of graphite plates is done with blown air whenever required
- The graphite plates are overlapping each others to enhance the overall leak tightness
Performances :
- Average life time of graphite plates : 4 to 5 years
- Fast payback, typically from 6 to 18 months depending on the condition of the seal to be replaced
