Rotary kiln working principle
The rotary kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly around its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, the materials gradually move down towards the lower end and may undergo a certain amount of stirring and mixing.
Hot gases pass along the kiln sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current).
The hot gases may be generated in an external furnace or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or ‘firing pipe’), which acts like a large burner. The fuel may be gas, oil or pulverized coal.
