rotary kiln zones in detail

Preheating Zone/Kiln Inlet Zone. The first reaction zone of rotary kiln system is known as the preheating zone. Here the charge gets heated up to about 800℃ before entering the calcining zone. Bricks in this area are prone to chemical attack from gases containing alkali and sulphur

    Rotary Kiln - an overview | ScienceDirect Topics

    The rotary kiln gasifier is used in several applications, varying from industrial waste to cement production and the reactor accomplishes two objectives simultaneously: (1) moving solids into and out of a high temperature reaction zone and (2) assuring thorough mixing of the solids during reaction. The kiln is typically comprised of a steel cylindrical shell lined with abrasion-resistant refractory – to prevent

    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

Direct-fired rotary kilns can operate in either the co-current mode, where combustion gases and solids move in the same direction, or in the counter current mode, where the gases and solids move in opposition to each other. While all FEECO kilns are custom engineered around the material to be processed and the unique processing
