  • Rotary kilns - Metso

    Pelletization process. Because the induration of the pellets occur in the rotary kiln, the pellets produced in a Grate-KilnTM system are consistently of higher quality than those produced in a straight grate. The rotary kiln provides constant mixing of the pellets, bringing all the pellets to the same temperature.

  • Upgrading Phosphate Ores with Rotary Kilns

    How Phosphate Rotary Kilns Work. Rotary kilns (sometimes called calciners) are an advanced thermal processing device used for high temperature processing, typically with the intention of causing a physical change or chemical reaction within the material. Rotary kilns are available in two configurations: direct-fired and indirect-fired.

  • Grate kiln systems - Metso

    The process system is designed so that material transfer from the grate to the kiln occurs when the material on the grate is sufficiently preheated to have the requisite indurate strength for subsequent processing in the rotary kiln. A rotary kiln is a steel round shell with refractory lining that rotates. This shell is rotated by a drive gear ...
