The failure of steel chains which are used in rotary cement kilns costs cement companies a signiicant price. This study investigated the causes of chains failure at the Kufa cement plant and proposes new materials that can serve for a prolonged period of time. Two grades of steel chains were investigated including DIN (AISI 10F) and St37.
As with so much else in the cement sector, the exact reasons for a critical temperature increase differ from kiln to kiln, plant to plant and country to country. However, the main possible effects are the same everywhere: Increasing shell temperatures can lead to hot spots and, often, the need to stop the kiln.
Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silicabearing minerals to form a mixture of calcium a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

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.

Rotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed. The kiln is set at a slight slope to assist in moving material through the drum.
Cement Kilns: Design features of rotary kilns. Design features of rotary cement kilns. The shell of the kiln is made of mild steel plate. Mild steel is the only viable material for the purpose, but presents the problem that the maximum temperature of the feed inside the kiln is over 1400°C, while the gas temperatures reach 1900°C.
CEMENT ROTARY KILN Questions Answers Question1: What is the maximum continuous shell temperature a kiln stands without permanent damage to the shell? Answer1: The maximum recommended kiln shell temperature varies by plant, by country and by kiln manufacturer, despite the fact that most kiln shells are made of low alloy carbon steel.
