Rotary kiln - WikipediaA rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary kilns include: Cement · Lime · Refractories · Metakaolin · Titanium dioxide · Alumina · Vermiculite · Iron ore pellets. They are also used for roasting a wide variety of.cement rotary introduction,cement rotary introduction,Wet process rotary cement kilns: modeling and simulation .Based on a one-dimensional cell model, a simulation program for wet process rotary cement kilns with chain systems has been developed. With the aid of this simulation tool, the influence of chain systems on solid composition and temperature profiles, clinker throughput and fuel requirement is predicted and the design of.

A case study of high-temperature corrosion in rotary cement kilns

Introduction. Corrosion as far as cement is concerned is usually associated with its application in concrete and specifically the degradation of rebar in the concrete structure. The subject of reinforcement corrosion is well and widely described1-8, but descriptions of corrosion of the structures producing cement seldom appear.
