Laterite nickel ore smelting process for nickel-iron reduction, the main raw material is laterite nickel ore, reducing agent using cheap coal, peat, coal can be, the process steps are mainly material preheating treatment, reduction melting process, separation and refining three steps. When the equipment is running, the main drive motor transmits power to the open gear device through the main reducer to drive the kiln to rotate, and laterite nickel ore is calcined in the rotary kiln from the kiln tail. Due to the tilting and slow rotation of the cylinder, the material both rolls in the circumferential direction and moves in the axial direction to continue its process. Then, the generated clinker enters the cooler for cooling through the kiln head. The fuel is sprayed into the kiln from the kiln head, and the waste gas generated by combustion is exchanged with the material and exported from the kiln tail.
