Cement Rotary Kiln Laterite Ferronickel Rotary Kiln
Ⅰ. Basic introduction of laterite nickel-iron rotary kiln(Cement Rotary Kiln)
The company's large-scale laterite-nickel-iron rotary kiln series products can meet the production line matching of large-scale laterite-nickel ore smelting nickel projects. The company has the testing and testing methods of laterite ferronickel rotary kiln and sophisticated laterite ferronickel rotary kiln manufacturing equipment and manufacturing technology, forming a complete technology and production system integrating the design, manufacture, installation and commissioning services of laterite ferronickel rotary kiln.
Common specifications and models of laterite nickel-iron rotary kilns: φ4.4×100m, φ5.2×118m, Φ4.5×110, Φ4.5×110.
Ⅱ. Production process of laterite ferronickel rotary kiln(Cement Rotary Kiln)
Raw material field - screening, crushing and mixing ingredients - rotary kiln - submerged arc furnace - iron ladle desulfurization - refining converter - casting. On this basis, the development of raw material pre-drying, raw material pelletizing, rotary kiln energy saving and waste heat power generation, submerged arc furnace high-efficiency smelting and low melting point slag batching, bottom blowing or side blowing refining converter instead of top blowing converter, nickel iron pellets Chemical and other technologies, suitable for factories with different conditions.
Ⅲ. Process overview of laterite-nickel-iron rotary kiln(Cement Rotary Kiln)
The ore, limestone and reducing agent are screened and crushed in the raw material yard and the material preparation room, and then the mixed ingredients are sent to the rotary kiln.
In the laterite ferronickel rotary kiln, the raw materials are dried, roasted, and pre-reduced to make ferronickel at about 1000 °C. The flue gas of the rotary kiln is discharged after the waste heat boiler, dust removal and desulfurization, and the dust is mixed with the raw materials and then enters the cellar again.
The nickel slag is distributed into the submerged arc furnace through the feeding pipes at different positions according to the process requirements in a closed and insulated state. The submerged arc furnace is fully enclosed.
Ⅳ. Process characteristics of laterite-nickel-iron rotary kiln(Cement Rotary Kiln)
(1) The raw material has strong adaptability. Most suitable for high-medium, low-iron nickel oxide ores that are difficult to process using wet processes.
(2) The nickel-iron grade is high and the harmful elements are few. The desulfurization and converter refining process of this process can reduce the harmful elements of ferronickel, which is welcomed by steelmaking users.
(3) Energy saving and environmental protection, recycling. The raw material has a lot of moisture, and no dust is generated during the material yard and screening, crushing and transportation. The waste heat of the rotary kiln flue gas can be recovered as steam for power generation. After the flue gas desulfurization meets the environmental protection requirements, it is discharged into the atmosphere, and the rotary kiln and submerged arc furnace dust Return to the material yard; the submerged arc furnace gas is sent to the rotary kiln as fuel after being dedusted, and the slag becomes the raw material for the construction industry after water quenching. The waste heat of the converter flue gas is used to recover steam, and the gas is recycled. The slag is magnetically separated and returned to the furnace. The tailings can be used to pave roads or make cement. From the water-containing charge entering the rotary kiln to the whole process of iron and slag tapping in the submerged arc furnace, the charge is fully enclosed, which is environmentally friendly and energy-saving.
(4) The nickel slag ore is fed into the submerged arc furnace. The nickel slag produced by the rotary kiln is fed into the furnace at a high temperature above 900 °C. Compared with the cold material fed into the furnace, a lot of physical heat and chemical heat are saved, the consumption of electric energy and reducing agent is significantly reduced, and the production efficiency is improved.
