Coating Formation And Shell Cooling Fans In Cement Kiln

An external cooling of the kiln shell in the damaged area through a fan promotes the formation of coating also. Thereby the shell temperature is reduced locally, which decreases also the temperature inside the kiln. The meal or already formed clinker will solidify more likely on the cooled area than in the hotter neighborhood.

Stabilization Of Kiln Coating Industrial Efficiency

Coating formed on the brick working surface in the kiln burning zone lowers the shell temperature, reducing radiation heat losses and protecting the refractory material. Unstable coating easily leads to problems with the refractory material and causes loss of energy and disturbs stable kiln operation. Various measures can be taken to assist formation and maintenance of stable coating in the kiln

Longer Service Life By Efficient Rotary Kiln Cooling

By means of a new, large-area kiln shell cooling system, the coating conditions are stabilized and the service lives of the refrac-tory lining and the kiln itself are increased. This kiln shell cooling system primarily regulates the temperatures in the area between the middle supporting roller station and the outlet-end roller station the clinkering zone.

Automated Fan Systems Unlock Productivity Potential

The coating of the brick in the kiln becomes unstable. Keeping the shell temperature within a certain range encourages build-up of coating on the kiln brick, which protects the brick from wear. However, if the fans are left on the coating can grow to form rings or become excessively thick. The rings will disrupt kiln operation and coating ...
