Dust retention curtain incorporated
7,000 - 14,000 service hours for the wear parts (dependent on the process conditions).
The lamella seal consists of a non-rotating cylindrical ring of steel plates fitted around the kiln on the kiln hood. This cylindrical ring supports a number of special steel lamellae which slide on the circular cooling mantle surrounding the kiln outlet & inlet section.
The lamella seal consists of two sets of spring lamellae and heat-resistant fabric.
The inner set of lamellae supporting the fabric is exposed to the intense heat of the kiln. Over a period of time the lamellae may lose their original spring characteristics. To protect the outer set of lamellae and enable them to maintain their resilience, a layer of heat-resistant fabric is positioned between the two sets of steel lamellae.
The cooling mantle is constructed from heat-resistant plate and is positioned on the kiln shell and fixed by a number of spring plates.
To prevent overheating of the outlet sectors and sealing parts, a separate fan supplies cooling air via a circular manifold to the space between the kiln shell and the cooling mantle.
In the concentric dust chamber the escaping dust is collected and is then returned directly to the cooler via a chute.
