    Everything depends on design. Generally kilns diameter vary from 3 to 6m, and length from 40 to 200m. From maintenance point of view very important parameter is shell thickness: 20mm – small shell thickness; 40mm – standard shell thickness. There is also some useful parameter of rotary kiln design – thickness / diameter ratio

    Rotary kilns are traditionally large steel pipes, several meters in diameter and up to 100 m in length (in larger facilities, however, kiln lengths of over 100 m are not uncommon). To protect the steel from intense heat, however, each kiln is lined with bricks composed of refractory material, which is typically a blend of various ceramic compounds
