Grate kiln systems

The final induration of the pellet is accomplished in a rotary kiln, wherein the principal heat transfer mechanism is radiation from the system's main burner. 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.
