Rotary kilns (sometimes called calciners or rotary furnaces) are used for thermal treatment processes such as calcination, sintering, pyrolysis and firing, as well as for oxidation and reduction.These treatments can be applied to powders, granulates, suspensions and green bodies.A rotary kiln consists of a cylindrical, rotating body mounted between stationary …

VTT's unique electric rotary kiln supports carbon-intensive industries research and develop clean, flexible, and more efficient alternatives to traditional, emissions-heavy processes used in lime and cement production. We'll help you to find ways to replace fossil-fuel based solutions for calcination – while allowing CO2 capture in the process.

THE SEMIDRY (LEPOL) KILN. The drying, the dissociation of the chemical water, the preheating to calcining temperature, and even partial calcination in this system takes place outside the rotary kiln, i.e, in the grate preheater.Hence, the rotary kiln proper has only to complete the calcination and form the clinker com· pounds. The length of the zones in …

The rotary calcination process runs on similar principals to those of clinkerization. Which is not really surprising, given it uses much the same equipment. ... in the cement kiln temperatures reach over 1500°C, whereas clay is calcined at 650-850°C. Calcined clay production thus consumes less than half of the specific thermal energy of ...
