The Six Main Processes A Rotary Kiln Can Accomplish
The Six Main Processes A Kiln Can Accomplish. Calcination is the process of heating a material to a point that chemical separation occurs, such as when creating inorganic materials. For example, calcium carbonate can be heated to create calcium oxide + carbon dioxide. This same process can also be used to remove bound moisture from a substance.

MoreKiln vs flash calciner - FLSmidth
TK: Both the rotary kiln approach and the suspension calciner effectively convert spodumene. The primary consideration of which approach is best is the concentrate particle size distribution (PSD). Concentrate produced via dense media separation (DMS) often results in feed size from 3mm to as large as 12mm or sometimes larger.

Rotary kiln - Wikipedia
A rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary kilns include: Cement; Lime; Refractories; Metakaolin; Titanium dioxide; Alumina; Vermiculite; Iron ore pellets; They are also used for roasting a wide variety of sulfide ores prior to metal extraction.
