Carbon Anode Production [x4e6m56wv9n3]

Rotary kiln is made up of strong reinforced steel outer shell that is coated with a high resistant inner lining, support by special roller and drive gear to move the contents in a continuous rotating motion and the heat exchanger produces a temperature up to 1500 oC. As the rotary kiln rotates, it will undergo a process of string and mixing.
