Product Description

Enverinomental Friendly Shaft Kiln And Rotary Kiln In Quicklime Production Plant


Lime Kiln Introduction:
Lime Kiln is the ideal equipment to produce quicklime by the calcination of limestone (calcium carbonate). Usually, it has two types: lime rotary kiln and lime vertical kiln. These two types calcination kiln has different advantages. We will suggest you the suitable type according to the different suitations.


Comprehensive Analysis and Comparison of Shaft Kiln and Rotary Kiln

Shaft kilns and rotary kilns are important equipment for calcination of materials. In operation, the processes of shaft kilns and rotary kilns are different, and each has advantages and disadvantages. A comprehensive analysis of their advantages and disadvantages is as follows:


1. The shaft kiln occupies a small area and the heat consumption is relatively small; however, due to the complex structure of the kiln, the materials are internally sealed and calcined, and the heating is uneven, and the product has a high overburning rate, which requires the formation of a type muffle furnace temperature The field effect will greatly increase the activity of the product. The sulfur in the fuel is easy to adhere, and the sulfur content of the product will increase; and due to the requirements of the airflow and pressure in the furnace, it is generally suitable for burning large pieces to ensure the air permeability in the furnace.


2. The rotary kiln occupies a large area and has a large heat loss; but the kiln body is simple and has smooth air flow. It is an open calcination, and sulfur-containing flue gas can be discharged in time. The sulfur in the fuel is not easy to adhere, and the sulfur content in the product is reduced; Because the material rolls forward uniformly inside, the heating is even, and the product activity is high. Moreover, the multi-channel burner of the rotary kiln realizes green energy saving, and is suitable for a wide range of raw material size, and is particularly suitable for burning small limestone.

3. The shaft kiln that can produce high active ash is basically a kiln introduced from abroad, and its investment level is about 10 million yuan to produce 100 tons of active ash per day; when the rotary kiln was introduced from abroad, its investment was greater than that of the shaft kiln, but After domestic digestion and absorption, especially the introduction and digestion of foreign preheating and cooling technologies, the rotary kiln can be successfully applied to small-scale production, and the investment has also dropped significantly. The investment level is basically similar to that of imported shaft kilns.


4. The shaft kiln has good sealing properties, large heat loss, and relatively low fuel consumption; the rotary kiln has a large heat loss due to the long cylinder, but after the use of preheating and cooling technology, the heat energy can be effectively used, and its fuel consumption has been It can be reduced to a reasonable level, and the production cost of the product can be effectively controlled.


It can be said that the rotary kiln and the shaft kiln have their own advantages in the operation. During the operation, the user can choose the appropriate equipment according to the actual situation in the operation.
