Lime processing plant is a lime production line to make lime which is also called quicklime. When limestone(calcium carbonate) is calcined, the decomposition of limestone will happen and produces quicklime(CaO) and carbon dioxide(CO₂). Since the temperature needed is high for the calcining, the limestone is often calcined in lime kilns, such as rotary lime kiln and vertical kiln. Of course, there are other machines for the lime processing plant. Daswell machinery, with rich experience and professional knowledge, offers tailored turnkey solutions for lime manufacturing plant, including plant designing and supplying of machinery. Daswell designed and built lime processing plant is of high cost efficiency and can produce high quality quicklime with great highness and uniformity.

Lime Processing Machinery
Lime calcining plant consists of a set of machines, while the lime kiln is the core equipment. Currently, there are mainly two kinds of lime kilns, one is rotary lime kiln and vertical lime kiln. Besides, there are many other machines. For example, there are crushers to crush the limestone into proper sizes. There are conveying systems to handle with the material. And there are silos to store the raw material and final product. For the consideration of environment, there are dust collectors to collect dust produced in the processing. Finally, there may have packing machines to pack the final product automatically. For modern rotary lime kiln system, there are often stand-alone vertical preheater and vertical coolers to reduce the length of rotary lime kiln the consumption of energy and improve the efficiency of the whole quicklime plant.
Lime Manufacturing Process
Mainly, there are several processes in the manufacturing of quicklime in lime plant. That is, the crushing process, conveying process, preheating, calcining and cooling systems, and dust collecting, finally the packing process. Firstly, the sifted and washed limestone will be crushed to proper sizes so as to feed in the kiln. Then the feed limestone will be transferred to raw material silo for use. For the preheating, calcining and cooling process, they are conducted in the vertical lime kiln itself , for the vertical shaft lime kiln consists of these three respective chambers. However, for the rotary lime kiln, it is also equipped with extra preheater and cooler. The feed limestone is preheated in the preheater with the hot exhausted air from rotary lime kiln. And the preheated limestone will go to the rotary lime kiln for calcining. After the calcining process, the hot quicklime will be cooled down with vertical cooler so that they can be handled by conveyors. And then the burnt lime will go through dust collector. Finally, the quicklime will be stored in silo waiting for packing.
