Grate kiln pelletizing plant
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.
