Applied material:
Limonite rotary kiln is a kind of equipment for calcining, roasting, treating and sintering limonite ore. It is widely used in metallurgy, building materials, chemical and environmental protection industries.
The limonite rotary kiln is mainly composed of rotary kiln cylinder, support device, transmission device, rim support device, sealing device, flue gas piping device and other parts.
The working principle of limonite rotary kiln is to convert limonite ore into high quality iron ore products by entering the rotary kiln cylinder and calcining it at high temperature. In the rotary kiln cylinder, the ore is in constant contact and friction with the high temperature gas, so that its internal moisture and impurities are evaporated and decomposed.
The rolling motion of the ore in the rotary kiln barrel makes its surface constantly renewed, making the calcination more uniform and thorough. During the calcination process, the ore gradually softens, melts and combines to form a granular iron ore product for subsequent processing or use.
Working Principle:
1. the limonite powder ore with particle size less than 10mm and moisture less than 15% is mixed with coal dust in the weight proportion of 0-8% into the rotary kiln; the limonite powder ore completes the drying, magnetization, arsenic removal and desulphurization process in the same rotary kiln with a rotational speed of 0.8-1.5 rpm; the temperature of the roasting zone of the rotary kiln is 800±150°C and the temperature of the drying zone is 350±80°C.
3. For low iron grade high arsenic and sulphur impurity limonite powder ore for coal distribution, drying, roasting, magnetization and removal of arsenic and sulphur impurities in the same kiln, the process is simplified, the roasted ore is quenched and graded with water and then magnetically separated, after magnetic separation to obtain a magnetic iron ore concentrate with high iron grade, low arsenic and sulphur impurities; widely used in the beneficiation of ores and waste slag containing weakly magnetic iron minerals.
Features And Advantages
1. The limonite rotary kiln adopts advanced technology and equipment, which can remove impurities and moisture from the ore at high temperature, thus improving the quality and yield of iron ore.
2. In the process of calcination, the high temperature gas is recovered by preheating in the limonite rotary kiln, which reduces the energy loss and thus achieves low energy consumption production.
3. The limonite rotary kiln adopts advanced dust removal equipment and flue gas treatment system, which can effectively control the emission of exhaust gas and dust during the calcination process and realize environmental protection production.
4. The limonite rotary kiln is made of high quality refractory materials and high quality steel plates, which can guarantee the service life of the equipment and the quality of the products.
