Raw Ore: Lithium-bearing pegmatite ore (mainly Spodumene) Li₂O Grade: 1.15% Concentrate Grade: 5.5% Li₂O
We can provide different type graphitization furnace for changing carbon material into graphite include lengthwise graphitization furnace (LWG furnace), Acheson graphitization furnace (AC furnace) and Box type graphitization furnace (Box Furnace). Graphitization processing has different heating curve and treatment cycle for anode material, special graphite, Isostatic graphite, HP electrode & pins, UHP electrodes & pins.
Design temperature: Max. 3100°C
Loading capacity: 220t per furnace
HP electrode, UHP electrode baking and rebaking process; Artificial graphite anode material precarbonization process; Special graphite and Isostatic graphite…
The disordered microcrystalline structure formed by a large number of carbon atoms is ordered, the interlayer spacing is reduced, thereby obtaining the physical and chemical properties required for artificial graphite anode materials.
The carbonaceous material in the crucible is subjected to high temperature heat treatment to make it have the characteristics of graphite crystal structure.
Apart from the Acheson furnace, Prominer can also design the length-wise graphitization furnace and grid box graphitization furnace. Formaking the high end anode materials, the Acheson furnace is more stable and mature.
LWG furnaces are more efficient in UHP Graphitization, the working time is reduced from 80 hours/furnace to 24 hours/furnace with lower power consumption.
The box-type graphitization is based on the Acheson graphitization furnace, and a carbon plate box is set in the furnace, which is equivalent to the enlargement of the crucible ruler, thereby bringing a higher single-furnace output.
Graphitization accounts for about 50% of the cost of artificial graphite and is an important processing link of artificial graphite.
The LWG process heats the product directly for electrode processing, but need crucible for Anode material.
