This is determined by (i) the maximum flow rate of the proposed burden through a kiln, and (ii) the residence time at temperatures that would allow sufficient reduction to take place. A calculation method was developed that allows for the prediction of the bed profile and residence time in a rotary kiln

    Historically, the construction of rotary kiln shells has closely paralleled the construction of boilers. The engineers who pioneered the first rotary kilns all had a background in locomotive construction. Shell sections were made from flat rolled plate, of thickness typically in the range 18-25 mm

    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

This simple calculation already shows the steep increase in the cost of production loss when simply replacing the 4000t/day by higher production rates like 10,000t/day or more
