Product Description

Laterite Nickel Ore Rotary Kiln is an ideal equipment for calcining nickel ore, which is mainly composed of kiln head, kiln body, kiln tail, Rotary kiln support frame, preheating tower, cooler, etc., with simple and reasonable structure. Laterite Nickel Ore Rotary Kiln is welded with carbon steel plate. The barrel is supported on the supporting device by a tire, and a hydraulic retaining wheel is set on the supporting device to prevent the barrel from axial displacement during rotation. In order to prevent cold air from entering the barrel and smoke and dust from overflowing the barrel during production, a sealing device is also set at the inlet and outlet ends of the barrel.

Feature

1. Energy saving: The main energy source of laterite nickel ore Rotary kiln smelting is coal, not expensive coke or electric energy.

2. Wide range of materials: raw materials for laterite nickel ore Rotary kiln production can be freely selected, and various laterite nickel ores in Southeast Asia can be used.

3. High production quality: nickel iron produced by laterite nickel ore Rotary kiln is of high quality, containing about 20% Ni, and can be directly used as raw material for stainless steel production.

4. Diversified uses: The nickel products produced have a wider range of uses and can also be used as a coolant for molten steel melting.

Working principle

The processing step is to grind the raw laterite nickel ore, mix it with carbon containing materials and flux limestone, and then continuously feed it into the laterite nickel ore Rotary kiln. In the Rotary kiln of laterite nickel ore, the hot gas generated by the combustion of materials and coal moves in countercurrent, and undergoes all smelting steps drying, dehydration, reduction and metal growth. The metal is generated under the semi melting condition in laterite nickel ore Rotary kiln. The sintered material frit comes out of the Rotary kiln and is crushed by water. After grinding, the reduced nickel iron alloy is separated from the discharged frit by gravity separation and magnetic separator.
