Rotary Kiln an overview ScienceDirect Topics

Graeme Moir, in Advanced Concrete Technology, 2003. 1.3.2 The modern rotary kiln. The rotary kilns used in the first half of the twentieth century were wet process kilns which were fed with raw mix in the form of a slurry. Moisture contents were typically 40% by mass and although the wet process enabled the raw mix to be homogenized easily, it carried a very heavy fuel penalty as the water

The cement kiln

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.

Cement Kilns: Wet and semi-wet process kilns

Two ways were identified to improve this situation by the early rotary kiln operators: to lengthen the kiln, allowing more space for drying to take place; to line the kiln with “lifters” to agitate the slurry and pour it through the gas stream, and to add extra surface area.

Rotating Kiln an overview ScienceDirect Topics

The TOSCO (The Oil Shale Corporation) process used a rotating kiln that was reminiscent of a cement kiln in which heat was transferred to the shale by ceramic balls heated in an exterior burner (Figure 4.6) (Whitcombe and Vawter, 1976).The process, which was initiated in the 1960s and 1970s and developed by the Oil Shale Corporation, is more correctly described as a retorting/upgrading process

Manufacturing of Portland Cement Process and Materials

The slurry on being sprayed against a hot surface of a flexible chain loses moisture and becomes flakes. These flakes peel off and fall on the floor. The rotation of the rotary kiln causes the flakes to move from the upper end towards the lower end of the kiln subjecting itself to higher and higher temperatures. The kiln is fired from the lower

Reinforcement Learning-Based Supervisory Control Strategy

Jan 01, 2008· The alumina rotary kiln process is described as follows. Raw material slurry is sprayed into the rotary kiln from upper end (the kiln tail). At the lower end (the kiln head), the coal powders from the coal injector and the primary air from the air blower are mixed into bi-phase fuel flow, which is sprayed into the kiln head hood and combusts with the secondary air, which comes from the cooler.
