Indirect Fired Rotary Kiln/Iron Ore Concentration plant

The indirect fired rotary kiln has a compact and simple structure, reasonable layout, improve the materials and thermal heat exchange rate, so that the material drying effect is more better; less investment foundation, which is only half of the same production of single cylinder dryer, and reduce the time investment. It can be used in iron ore concentration plant. It is featured by reliable operation, low energy consumption, high thermal efficiency; at the same time, it is easy to achieve automatic control, reduce operator labor-saving resources.

The indirect fired rotary kiln is mainly used for drying certain humidity and particle size range of particulate materials. Such as sand, slag, cinder, small particle size clay, and the materials that are not afraid of high temperature and dust soiled small particulate materials. After drying, the moisture content of materials can reach 1-0.5%.

The working principle of indirect fired rotary kiln

Materials from the feed device enter the inner layer of the rotary drum, downstream drying, the materials in the inner copy board are constantly scattered and make spiral marching to achieve heat exchange. And the materials that move to the other end of the inner layer enter the middle for countercurrent drying.

The features of indirect fired rotary kiln

1.Equipment investment is one sixth of imported products.

2.The final moisture of materials ensures that less than 0.5%, and it is the preferred product for dry mortar and slag powder production line.

3.Self-cylinder insulation and thermal efficiency is more than 70% (the traditional single-cylinder dryer thermal efficiency is only 35%), which can improve the thermal efficiency of 35%.

4.The fuel can be adapted to the coal, oil, gas. It can bake block material, pellets and powder materials with less 20mm.

5.Single cylinder dryer reduces the area of about 50%, construction investment is reduced by about 50%, and 60% power consumption.

6.You can easily control the final moisture indicators according to user requirements.

7.The outlet temperature is low, the dust removal equipment can be used for a long time.

8.Use wheels to drive.
