working principle:
Lime kiln is installed with slope, generally 4-5%. The motor drives the gearwheels to rotate. The materials to be calcinated are put into the feeding port, which is on the higher side. While the lime rotary kiln is rotating, materials go through the cylinder of lime kiln. The cylinder can be divided into four areas: feeding area, preheating area, main calcinating area and cooling area. After going through these four areas, materials are discharged. Generally the discharging port of lime kiln is connected with cooler so that the discharged materials can go to the cooler to lower the temperature.
