Rotary dryers,Rotary kiln

Mineral Roasting Kiln is a kind of rotary kiln furnace used to roasting various mineral materials. It can provide a 500 to 1450℃ roasting temperature. Common materials which Taeda mineral rotary kiln is suitable to dispose contain:sponge iron,iron ore,nickle ore,chrome,magnesium ore,bauxite ore,non-ferrous metal,magnetic powder,catalyst,Precious metals,dolomite, kaolin, cement, limestone, active carbon and coke,etc.

Mineral Roasting Kiln is a cylindrical vessel, slightly inclining it to the horizontal position, which is rotated slowly toward its axis. The material to be processed is fed into the upper end of the cylinder. As the Mineral Roasting Kiln rotates, material gradually moves down towards the lower end, and may undergo a certain amount of stirring and mixing. When hot gases pass along the kiln, sometimes it is 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 Bunsen burner. Its fuel may be gas, oil or pulverized coal.
