Lime Kiln Manufacturer

Lime kiln is also known as quicklime kiln or limestone kiln. And according to shapes and operation principles, there are rotary lime kilns and vertical lime kilns. Quicklime kiln is the core equipment of quicklime plant to burn limestone to produce quicklime or burnt lime. Lime kiln has been used for this application for long time. However, lack of high technology as well as quality materials, the traditional lime kilns often consumes lot of energy in the lime manufacturing process. With the development of high technology and quality materials, modern limestone kilns are more cost efficient than the traditional ones. As a professional lime kilns manufacturer, Daswell machinery provides high quality lime kilns, whether the rotary lime kiln or the vertical kiln, producing high capacity of uniform quicklime with low energy consumption.

Rotary Lime Kiln

Rotary lime kiln is also called lime rotary kiln or limestone rotary kiln. It is used for the calcination of limestone to make quicklime. And specifically speaking, it is a slightly horizontal device that can rotate continuously to burn down ...

Limestone Kiln Process

The working principles of limestone kilns are the same for rotary lime kiln and vertical lime kiln. It is well known that limestone contains mainly calcium carbonate. And when calcium carbonate is heated at proper high temperatures, usually above 1000 degrees, the decomposition of calcium carbonate will produce quicklime and carbon dioxide. And the burnt lime is the end product.

For the modern rotary lime kiln with preheater and cooler, the sifted limestone will first go to the preheater. In the preheater, the hot air from the rotary lime kiln will preheat the limestone to about 800 degrees, which as a result saves lot of energy as well as money. Then the limestone will be transferred to the rotary lime kiln. After the constant rotating of rotary lime kiln for required time, the thoroughly burnt lime will be transported to the cooler. From there, the hot quicklime will be cooled down so that they can be packed.

As for the vertical lime kiln, it contains three parts from up to down: preheating, calcining and cooling. When the limestone is feed from the top of vertical lime kiln, the limestone will go through these three parts and become burnt lime. Finally, the quicklime will be discharged from the low end of the vertical lime kiln.

Differences between Rotary Lime Kiln and Vertical Lime Kiln

The differences of rotary lime kiln and vertical lime kiln lie in that they are different in shapes and constructions. The rotary lime kiln is slightly inclined to horizontal and rotates on a set of riding rings. Traditionally, in order to burn down the limestone thoroughly, rotary lime kiln is often very long. However, modern rotary lime kiln tends to be shorter and is equipped with pre-heater and cooler to save energy as well enhance quicklime plant efficiency. For the vertical shaft lime kiln, as the name implies, is vertical. And all the processes can be done in the vertical lime kiln alone. As for capacity, rotary lime kiln can produce quicklime with larger capacity than vertical lime kiln. Daswell rotary lime kiln can produce quicklime 150-1200 ton/day, while the capacity of vertical lime kiln is 100-500 ton/day.

How to Choose Lime Kilns

As stated above, Daswell provides both rotary lime kilns and vertical lime kilns. And all these lime kilns can be customized according to customer’s needs. So how can you choose a proper lime kiln? There are several factors to consider.

  1. End product quality. The quality of quicklime can affect which lime kilns to choose. It is thought that rotary lime kiln can burn limestone more thoroughly than vertical lime kiln.
  2. End product applications. The use of quicklime can impact what types of lime kiln you want for your lime calcination plant. Usually, the quicklime produced from vertical lime kiln can be used to produce hydrated lime by reacting with water.
  3. Production capacity. Daswell rotary lime kilns can produce high capacity of burnt lime about 150-1200 ton/day, while the vertical lime kilns can produce quicklime 100-500 ton/day.
  4. The properties of raw materials. The quality of limestone can affect the quality end product which in return impact which types of lime kiln you want.
