Rotary kilns

Latest drive systems for rotary kilns

The rotary kiln is the core of lime and cement clinker production. In the slightly inclined cylindrical tube, which rotates around its longitudinal axis during the firing process, the lime powder is heated up to 1450 °C and burned into cement clinker. The rotation has both a transport and an air injection effect. The length of such a kiln can be well over 100 meters. In this type of kiln, the limestone is added at the slightly higher end and slowly passes through the kiln due to the rotation. All drive elements must also be inclined accordingly. FLENDER offers the latest drive systems for rotary kilns.
