Jul 08, 2018 The Sintering Temperature (ST) in the burning zone of the alumina rotary kiln determines the quality of the alumina clinker directly and the energy consumption. What is more, the ST is a key controlled parameter to the alumina rotary kiln. In this paper, a kind of Phase-Space-Reconstruction-based (PSR-based) prediction methods are proposed to accurately predict the ST. After comparative

Rotary Kilns. A rotary kiln is a continuous process designed specifically for drying, calcining, processing, or sintering bulk materials. The rotary kiln heated chamber is a long horizontal tube that is rotated with one end slightly elevated. The bulk material is continuously fed into the elevated end of the tube and cascades down the length of

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
