Laterite Nickel Ore Briquetting


Laterite nickel ore resources are surface weathering crust deposits formed by weathering-leaching-sedimentation of nickel sulfide ore bodies. The world’s laterite nickel ore is distributed in tropical countries within 30 degrees north and south of the equator line, concentrated in the tropical-subtropical zone of the Pacific Rim area.

Laterite Nickel Ore

The laterite nickel ore briquetting machine can press the mixed laterite nickel ore powder according to the process requirements of the reduction and roasting to form nickel-containing pellets of different shapes and sizes, which will be delivered to the rotary kiln for reduction and roasting after drying.

The finished product after being pressed by the ball press is energy-saving and environmentally friendly and is convenient for storage and processing, which can bring benefits to the enterprise.

The ball press ensures that the material can enter the roller area evenly by dosing. The variable frequency speed regulating motor with constant torque provides power for the screw feeding device, the worm gear reducer rotates, and the material enters the main feeding port through the belt.  Therefore, it is necessary to ensure that the pressing material content of the screw feeder is equal to the content of the material required by the principal machine to get stable quality pellets. If the feed amount is too small, the briquette cannot be formed; if the feed amount is too large, the feed device will be overloaded. Therefore, the normal operation of the ball press is inseparable from the correct operation and skilled technology.

Laterite nickel ore briquetting process

Collection of Laterite Nickel Ore: Gathering the laterite nickel ore, which is typically obtained from mining operations.

Drying: Drying the ore to reduce its moisture content. Low moisture content is essential for efficient briquetting.

Mixing with Binders: Combining the dried laterite nickel ore with binders. Binders are materials that help hold the briquettes together during and after the briquetting process. Common binders include various types of starches or other adhesive agents.

Briquetting Machine: The mixture of laterite nickel ore and binders is fed into a briquetting machine, where it undergoes compaction under high pressure. The machine may have specific dies or molds to shape the briquettes.

Cooling/Curing (Optional): Allowing the formed briquettes to cool or cure. This step helps in solidifying the briquettes and improving their strength.

Storage and Transportation: The finished laterite nickel ore briquettes are ready for storage or transportation. Briquettes are more compact and easier to handle than loose ore fines.

Laterite nickel ore briquetting is a process that involves the agglomeration of finely divided laterite nickel ore particles into briquettes under high pressure. Laterite nickel ore is a type of nickel ore that is mainly composed of nickel oxide minerals and other impurities. The briquetting process aims to transform the ore fines or powder into a more convenient and transportable form for further processing, such as smelting or direct reduction in a furnace.
