Aug 19, 2011 By 1900, Atlas Cement Company, based in the Lehigh Valley, had 29 rotary cement kilns producing cement 10 times more rapidly than earlier kilns. By this point Portland cement had undergone a large number of incremental improvements, but its place at the top of the global cement pile was far from assured. 11

Calcined petroleum coke is a critical ingredient in the production of aluminum. It is created by placing high quality raw green petroleum coke into rotary kilns, where it is heated to temperatures between 1200 to 1350 C (2192 to 2460 F). The high temperatures remove excess moisture, extract all remaining hydrocarbons and modify the ...

before the feed enters the rotary kiln. The precalcination of the feed brings many advantages, the most important of which is high kiln output from a relatively short and small-diameter rotary kiln. Almost all new kilns installed since 1980 have been of this type. Figure 1.4 illustrates the main features of a precalciner kiln.
