    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. Direct-fired kilns utilize direct contact between the material and

    May 01, 2017 The rotary kiln at the Lake Charles calciner failed on December 25, 2015. In January 2016, Alcoa said calcining operations at the plant were likely to be offline for at least five months. At the time of the outage, the calciner produced about 250,000 mt/year of CPC for Alcoa's smelters, and sourced green coke from various oil refineries
