Dry process rotary kiln for cement plant

Temperature Measurements in Cement Manufacture

The rotary kiln is the key component in a cement plant. It is a long steel cylinder, lined with refractory brickwork to protect the outer shell from the high temperatures of the interior. The kiln is very large, up to 4 m diameter and up to 50 m long. It typically rotates three to five times per minute.

PDF 11.6 Portland Cement Manufacturing

In the wet process and long dry process, all of the pyroprocessing activity occurs in the rotary kiln. Depending on the process type, kilns have length-to-diameter ratios in the range of 15:1 to 40:1. While some wet process kilns may be as long as 210 m (700 ft), many wet process kilns and all dry process kilns are shorter.

US5572938A - Oxygen lancing for production of cement

Oxygen is lanced into the main combustion reaction of a cement kiln to increase heat transfer to the clinker bed and to increase clinker production. Oxygen is separately lanced along the floor, i.e. the lowest wall of the kiln, to delay mixing with the flame to provide deep staging. The deeply staged oxygen flow is adjusted frequently to control emissions and stabilize the burning zone while

Cement Kilns: Wet and semi-wet process kilns

The resulting "cake" could be fed directly to a rotary kiln - typically a converted wet kiln, or dried out in a preheater before feeding to a dry process kiln. The first example of the former was at Billingham in 1929, where ICI, who had plenty of experience of vacuum filtration in their other processes, used this for forty years to reduce
