Snowman formation pradeep kumar - SlideShare

The dust is the main culprit of the snowman formation and then the uneven distribution of air further aggravates the situation. The red river area is aerated more, the dust Is blown back into the kiln. In modern beam aerated cooler the sand blasting effect must be low. If it is so then the cooler plates slaught profile needs check.

Clinkerization - Cement Plant Optimization

The liquid phase plays an important role in coating formation and nodulisation. The liquid percentage at 1450 0 C can be estimated using the formula % Liquid content (1450 0C) = 3.0 x A+2.25 x F+S Where A=Al 2 O, F=Fe 2 O 3, S= MgO+K 2 O+Na 2 O+SO 3 In Clinker. The normal range of liquid phase is 22-27%.

Unusual. Normally these are not called 'snowmen' but rather 'rhino horns' (for obvious reasons) and are the result of high-alkali dust accumulating and then solidifying on the top of the burner pipe in the shape of a horn. If the 'horn' grows too heavy it can cause the burner to go out of alignment or in worst case even damage it internally.
