EXPERIMENTAL ANALYSIS AND MODELLING OF A ROTARY

Jan 01, 1980  It is suggested a methodology for experimental analysis and modelling of complex industrial processes, with an example of application to a rotary cement kiln. This methodology takes into account the multivariable and non-linear aspects of the process as well as the restrictions due to the non direct intervention on the process.

Cement - Wikipedia

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Concrete is the most widely used material in existence and is behind only water

the cement kiln system. Sulfur in cement kilns is derived from both kiln feed and from the kiln fuel. The form of the sulfur dictates the location in the kiln where the SO2 generation takes place. Sulfur in the fuel is oxidized in the burning zone or calciner, and is easily removed by reactive lime present in the kiln.
