rotary kiln sizing design slideshare

Sep 07, 2016· The size of a rotary kiln is not just a function of capacity, but also of the amount of heat that can be generated during processing due to combustible and/or volatizing material. Kiln length and diameter are calculated based on the maximum feed rate, the required retention time, and what the bed profile will need to be (how full of material the kiln will be)

rotary kiln

Kiln Shell This is made from rolled mild steel plate, usually between 15 and 30 mm thick, welded to form a cylinder which may be up to 230 m in length and up to 6 m in diameter. Upper limits on diameter are set by the tendency of the shell to deform under its own weight to an oval cross section, with consequent flexure during rotation

gypsum rotary kiln gypsumkiln agico

The length-to-diameter ratio of the gypsum rotary kiln is reduced from the original 20~25 to 14~15. The shortening of the length not only reduces the heat loss from the surface of the gypsum rotary kiln, but also reduces the floor space of the equipment, and the transmission power of the kiln body is also reduced accordingly
