Daswell Lime Manufacturing Process
The main operation principle of quicklime production plant is the decomposition or calcination of limestone which contains mainly calcium carbonate. In the calcination process, when calcium carbonate is heated with high but appropriate temperature, the calcium carbonate decomposes into quicklime(CaO) and carbon dioxide(CO₂).
For the manufacturing process of quicklime plant, there are several stages: crushing, calcining, de-dusting and packing. As for the specific quicklime manufacturing processes, they are different in quicklime plant with rotary lime kiln and with vertical lime kiln.
Quicklime plant with rotary lime kiln:
In the lime processing plant with rotary lime kiln, it is advisable to add vertical preheater and vertical cooler. For the perheater can use the hot air from rotary lime kiln to heat the limestone so that some of the limestone can decompose. And then they are transported to the rotary lime kiln which can save energy to burn the limestone. For the cooler, it can cool the burnt lime to about 60℃. So the process can be a little complex than the lime production line with vertical lime kiln. Firstly, the sifted limestone of required sizes is transferred to the silo in pre-heater by belt conveyor. Then in the pre-heater, the limestone is pre-heated to about 900 degrees, through which about 30%-40% of limestone will decompose. Then the preheated limestone is transferred to the heating rotary lime kiln. At the other end of rotary lime kiln, which is also material outlet, the energy material is put in though fire furnace. After the calcination process in rotary lime kiln, the burnt lime is transported to vertical cooler. Then the cooled quicklime will be transferred to product silo. Of course, to eliminate pollution, there are also dust collectors, pollutant air chimney.
Quicklime plant with vertical lime kiln:
The quicklime manufacturing process of quicklime plant with vertical kiln is mostly the same with that of lime calcination plant with rotary lime kiln.
Compared with the process of quicklime plant with vertical lime kiln, manufacturing process of quicklime plant with rotary lime kiln is more simple. There is no need for pre-heater and cooler, for the vertical lime kiln can respective chambers to pre-heat the limestone and cool down the burnt lime. As for other procedures, they are the same with lime calcination plant with rotary lime kiln.

Daswell Lime Processing Plant Machinery
Lime production plant contains a complete set of machinery, including lime kilns, dust collectors, conveying devices, blowers and so on. It is well known that the decomposition of limestone is often done in lime kilns such as rotary lime kiln or vertical lime kiln. So lime kiln is the core equipment of the quicklime production line. Daswell manufactures two kinds of lime kilns: rotary lime kiln and vertical lime kiln. For quicklime plant with rotary lime kiln, there are also vertical pre-heator to heat the limestone previously before going into the rotary lime kiln and vertical cooler to cool down the burnt lime from the kiln. When it comes to quicklime production plant with vertical shaft kiln, there is no need for extra preheator and cooler, for the vertical lime kiln is composed of these sectors. Except for the lime kiln, there is same need for other equipment, such as crushing and screening machines, dust collectors, conveying devices, product silos, blowers, firing systems and other machines. Daswell machinery provides reliable and durable lime processing machinery in line with customer’s specific needs in capacity, product applications and so on.

Applications of Quicklime
What is quicklime used for? The major use of quicklime is in steel making industry to neutralize the acidic oxides. Besides, ground quicklime can be used to produce aerated concrete blocks. And when reacted with water, quicklime can produce hydrated lime which also can be used in many industry. Daswell quicklime production plant can produce high quality quicklime with great uniform and purity. And the lime calcination plant of Daswell are of high efficiency, producing high capacity of quicklime with low energy consumption. With the development of modernization worldwide, quicklime is in urgent need. So it is of great economic value to build quicklime plant. And Daswell machinery is always here for you.
