The document discusses the grate-kiln process for producing iron ore pellets. It was originally developed by Allis Chalmers in 1960 as an improvement over the straight grate process. The grate-kiln process uses three connected machines - a traveling grate for drying and preheating pellets, a rotary kiln for induration, and an annular cooler. This allows independent control of …

One method used for pelletizing is the grate-kiln process, first established in 1960. During the past decade, the establishment of new grate-kiln plants has increased rapidly, especially in China, and new constructors of pellet plants have started to operate in the market.
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 …
