Kiln and Cooler Control and Optimisation. By Dr Y C Naidu Cement Plant Typical View Basics of Kiln and Cooler Kiln for pyroprocessing of raw material to make clinker Technology development from wet semiwet/semi dry- preheater kilns- precalciner kilns Cooler to cool clinker for further material conveying and also recuperation of heat
The advantages for the cement production process are manifold ranging from lower fuel consumption or higher alternative fuel substitution rate to more stable and smooth kiln operation. This, in turn, leads to less thermal stress on kiln parts, such as lining, resulting in fewer and shorter kiln stops.
A dry process kiln might be only 70m long and 6m wide but produce a similar quantity of clinker (usually measured in tonnes per day) as a wet process kiln of the same diameter but 200m in length. For the same output, a dry process kiln without a precalciner would be shorter than a wet process kiln but longer than a dry process kiln with a ...

Aug 30, 2012 Cement is the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.
The EO system was first started up, together with ABB experts, at Adana Cement on 11 May 2009 for process optimisation of clinker production line 4, which has an average capacity of 4500 tpd, including the control of the rotary kiln, calciner and clinker cooler. In a second step the raw mill of line 4 and coal mill 2 were included in the EO system.

This was a typical cement plant analysis: from early times, more scientific investigations performed additional analysis for Na, P, Cl, K, Ti, Mn, Zn, Sr, Ba, etc. No even moderately accurate method of analysis for Al 2 O 3 existed until the arrival of XRF in the 1960s. Reliable alkali metal analysis remained quite inaccessible until flame ...
