Prevent The Coating Of Rotary Kiln - CIPREF Bourgogne

Prevent The Coating Of Rotary Kiln - CIPREF Bourgogne

Coating thickness protection in the burning zone of a rotary cement kiln during operation is important from the viewpoint of the kiln productivity. In this paper, an integrated model is presented to estimate the coating thickness in the burning zone of a rotary cement kiln by using measured process variables and scanned shell temperature

The material cold end is the inlet of hot meal into the rotary kiln. In the transition zone, the materials start to melt and form the clinker nodules. The clinker reactions take place in the burning zone, or the hot end of the rotary kiln, where the clinker achieves a temperature of up to 1450 C11-13,19

Wet process kilns. The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter
