Indirect Fired Rotary Kiln Applications Part 3

Indirect fired rotary kilns can be beneficial when the material to be processed consists of finely divided solids. In a direct fired rotary kiln, the heat source is hot gas (products of combustion and air) which flows with an inherent velocity. These gases can carry discrete particles through form drag. The degree of entrainment depends on a

DAMAGES ON INDIRECTLY HEATED ROTARY KILNS
