clinker ball formation in semi wet kiln ppt
clinker ball formation in semi wet kiln ppt Semi-wet Process. As in the wet process the raw mix used in the semi-wet process is prepared as a slurry. Unlike the wet process the slurry is then dried in crusher-dryer before being delivered to a preheater for preheating, calcination and clinker formation in the rotary section of the kiln.

clinker ball formation in pre burning zone of the rotary kiln
Possible reasons for ringball formation, Raw mix design, High coal ash %. High liquid phase. Quality/ condition of refractory. High alkali feed. Burner pipe condition. Cooler condition. But to study all above reasons we have to run our kiln for 20 ~ 30 days continuously, we have technique to remove big clinker balls without stopping the kiln.

Thermodynamics of Clinker Formation
Model 2 shows that the formation of clinker is endothermic at all stages, whereas Model 1 suggests that, at high temperature, the reactions to form the silicates are highly exothermic.

rial that is fed into the kiln: in the wet process the material is fed into the kiln with a humidity of 30 to 40%; in the semi-wet process humidity is 20%; in the semi-dry process humidity is between 10 and 15% and in the dry process humidity is less than 1%. Specific heat consumption for each of the processes varies according to the process.

Cement Kilns: Wet and semi-wet process kilns
From this it is possible to calculate the minimum energy penalty for water evaporation: for a kiln using 1.56 kg of dry rawmix to make 1 kg clinker, 20% water in the feed requires 1.06 MJ, 30% requires 1.81, 40% requires 2.82 and 50% requires 4.32.

Clinkerization Cement Plant Optimization
Therefore, when SM is too high, nodulization becomes weak and clinkerization reaction (C3S formation) rate slows down, kiln becomes dusty and difficult to operate. While as when SM is too low, more melt is formed in kiln, issues like thick kiln coating, kiln melting, snowman formation in cooler are more prone. Normal range of SM is 2.3-2.7.
