The following are a few of the Technical Papers  available for download from the Repository: Understanding Clinker Liquid Phase This paper describes the importance of the liquid phase on clinker mineral formation and the impact of minor oxides on liquid phase viscosity and surface tension. Stop Kiln Shell Corrosion This paper describes the mechanism of kiln shell deterioration under the influence of temperature and chemical agents, and the economic impact of that on plant profitability. Present technologies to solve the problem are discussed and the use of ceramic coatings as a final solution is described. Nose Ring Lining This paper describes the thermal and mechanical constraints that lead to nose ring lining destruction, and it proposes simple solutions to each specific constraint during material selection, design, installation and curing. Long Lasting Cooler and Riser Linings This paper describes a unique lining design that encompasses the best of brick and castable. This self-anchored modular system is a proven concept already in use by many US cement plants. What Is The Optimum Thickness For My Kiln? This paper explains the correlation between lining thickness and brick performance in the rotary kiln. Kiln Heatup Schedule This paper discusses the many factors that affect kiln heatup. Eliminate Calcining Zone Rings This paper describes the mechanism of ring formation in the calcining zone of cement kilns, and proposes an inexpensive and reliable way to solve the problem without changing any kiln condition. The Wavy Refractory Lining This paper describes a patented lining designed to promote heat transfer in any type or size of rotary kiln, while inducing material mixing. It is a cost-effective alternative to tumblers, lifters, crosses and trefoils. Clinker Chemistry and Microscopy Made Easy This 16-page paper describes the practical use of clinker moduli such as LSF and SR, relating it to the main clinker properties assessed through microscopy. Carbide versus Zirconia Castables Against Buildups This paper describes the pros and cons of silicon carbide and zirconia low cement castables used in preheaters to combat buildups. Maximum Kiln Shell Temperature This paper discusses the risks of running kilns with hot and red spots on the shell, and defines, on scientific basis, the maximum safe operating shell temperature for well-maintained kilns.
