the process of long service life rotary kiln

Rotary kiln Wikipedia

Aug 23, 2006· Heat exchange in a rotary kiln may be by conduction, convection and radiation, in descending order of efficiency. In low-temperature processes, and in the cooler parts of long kilns lacking preheaters, the kiln is often furnished with internal heat exchangers to encourage heat exchange between the gas and the feed.

Rotary Kiln an overview ScienceDirect Topics

H.Y. Sohn, M. Olivas-Martinez, in Treatise on Process Metallurgy: Industrial Processes, 2014. 2.3.1.2.4.3 Rotary Kiln. The rotary kiln is used to process the lead-containing components resulting from the breaking and separation of waste batteries. The main components of a rotary kiln are an inclined cylindrical, refractory-lined reaction shaft equipped to rotate over rollers and a burner.

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
