The complete list of supporting equipment for the lime kiln, from the distributor to the ash discharge machine, is the core prerequisite for ensuring stable, low consumption, and compliant calcination of active lime. The entire configuration can be flexibly adjusted according to the daily production capacity of 300-500 tons of vertical kiln, and is suitable for the basic production needs of most industrial lime projects.
Priority should be given to configuring a flat material feeder at the kiln top, relying on the structural advantage of uniformly scattering materials at fixed points, to achieve a flatness deviation of less than 5cm on the material surface and avoid local sintering nodules. Compared with ordinary rotary material feeders, it is more suitable for the production needs of high activity lime. Equipped with an intelligent material level detection system, it provides real-time feedback on the height of the material level inside the kiln, and is linked with the feeding trolley to achieve precise material replenishment, eliminating problems such as empty burning and overflow.
The core configuration of the kiln is a simulated uniform pressure air cap, which is matched with a partitioned adjustable air supply pipeline to evenly distribute the air volume in the calcination zone, completely solving the pain points of lime burning and overburning. The activity of the finished product is stable and meets the standard of over 300ml. Paired with full process PLC automation control, it can not only reduce manual operation and maintenance intensity, but also ensure stable control of coal consumption per ton of ash standard within 130kg.
The bottom of the kiln is equipped with a sealed star shaped ash discharge valve and a rotary tower cone ash discharge machine, with an alternating air lock structure to prevent cold air from entering the kiln. The unloading process is smooth and free of dust, and the particle size of the discharged material is uniform without jamming, fully matching the long-term stable production needs of many industrial lime projects in Southwest and Northwest China.
