Continuous, External Heating Type Rotary Kiln
This machine is an indirect heating type of rotary kiln using electricity, heavy oil, or gas as the heat source. The shell, due to its equilateral hexagonal cross section, minimizes the "shear" of the material layer to provide a sharp distribution of residence time, enabling you to get stable and high quality products of uneven firing.
