Product Details

Yuhong Vertical Rotary Kiln, Shaft kiln for limestone, dolomite & clay minerals

♣100TPD Lime shaft kiln working site (heating source: coal)

♣ Main features of the lime shaft kiln

1. A Wide range of product reactivity, due to easy adjustability of operating temperatures

2. Large stone size range

3. High flexibility in adjusting the burning zone temperature

4. Low impurity level in the product, e.g. sulphur or fluorine

5. Suitable for gaseous , liquid and solid fuels

6. Low investment cost per ton of product due to high specific output per M2 of shaft cross section

7. All kiln parts designed for transportation in containers

8. All structural steel designed for easy erection with reduced welding work

♣ Working Process of the lime shaft kiln

The raw material to be calcined is charged at the top of the kiln. It it then pre-heated by the combustion gases in the counter-current before reaching the burning zone. In the burning zone the material is calcined by means of fuel introduced together with primary combustion air through radially arranged burner lances. Cooling air is introduced at the discharge part of the kiln to cool the product in a counter-current manner. The heated cooling air travels upwards to the burning zone and is used again there as the secondary combustion air.

From the top of the kiln he exhaust gas are directed to a dust collecting system.
