Abstract
Almost all of the powder materials, after having been calcined in a calcining furnace, are treated by the high temperature kiln exhaust without being directly fed into a rotary kiln, so that the materials may pass through at least two calcining zones in series so that they are calcined perfectly and uniformly before they are fed into the kiln, thereby contributing to make compact a rotary kiln in size and to improve overall thermal efficiency of the calcining and burning (sintering) apparatus.
