Traditional Rotary Kiln Overview 5-45t/h Capacity

A rotary kiln is a type of furnace commonly used to heat solid materials in the form of a powder, lump or other granular form. Rotary kilns are used for any number of purposes, from heating soil to remove volatile contaminants, to heating stones to remove moisture. By far the most common materials processed within a rotary kiln are cement, lime, and iron ore. For these most common rotary kiln materials, high temperatures in the range of 1100°C / 2000°F are used to instigate a chemical conversion (cement and lime) or to fuse fines (fine ore powder) into pellet form (iron ore). Most rotary kilns are direct fired – with a flame shooting into the kiln from the discharge end (the fire wall). As the kiln rotates, the heated material climbs the kiln wall before flopping down and flipping over. With each flop, the material travels a short distance along the length of the kiln because it is at a slight angle. This slight tilt allows the material to enter one end of the kiln and to exit the other end. This heating technique is most appropriate for powdered or pebble-like materials and this constant flopping and flipping of the material allows the heat to reach each particle without relying on conduction.
