  • Rotary Calciners FEECO International Inc.

    Rotary Calciners. Rotary calciners, also commonly called indirect kilns, are used in various calcination operations where exhaust gases must be minimized, when processing finely divided solids, or where temperature must be tightly controlled along the length of the kiln.. A calciner is comprised of a rotating drum inside a furnace, which is externally heated.

  • LIMESTONE CALCINATION IN ROTARY KILNS

    found in the literature for the calcination of limestone in rotary kilns to produce lime. The objective of this was to modify the model proposed by Perron et al. (1992) for petroleum coke calcination in order to describe calcination of limestone in rotary kilns. Modifications were introduced to the sub-models to account for variations in

  • Kiln vs flash calciner

    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.
