snowman formation - Page 1 of 1 - International Cement Review

2009-07-01  Snowman formation is caused by some of the flux in the clinker remaining as a liquid after the clinker falls into the cooler. The root cause solution is therefore to achieve more cooling in the kiln itself. There are numerous solutions to the problem of the removing the snowman itself. Blasters are the most commonly used method. Alternatives are acoustic cleaners or Denko´s "pusher".

Dalmia - Preheater

The kiln inlet chamber (also called smoke chamber) is at the base of the preheater where the preheater ends and rotary kiln starts. Here, raw mix coming down from the preheater goes to the kiln and gases come from the kiln and go up the preheater. Due to continuous circulation of gases rich in alkali or sulphur, refractories in this area are prone to coating formation and chemical attack.
