Rotary kiln for ferro manganese

The rotary kiln has a burner capable of mixed combustion with kerosene and electric furnace gas, and its length and the refractory inner diameter are 45 m and 3 m, respectively. The slant angle is 35/1000, the maximum rotation speed is 0.3 rpm, and the raw material residence time is at most 9 h. The pre-reduced ore that comes out of the rotary kiln is quickly cooled to 300 C in
