Advantages of graphite electrodes The discharge generates a high temperature on the electrodes. Graphite has a melting point of 3850 50 and a boiling point of 4250 . Copper has a melting point of 1083.4 0.2 and a boiling point of 2567 . Therefore, graphite has higher temperature resistance than copper. Disadvantages
H.Y. Sohn, M. Olivas-Martinez, in Treatise on Process Metallurgy Industrial Processes, 2014 188.8.131.52.4.3 Rotary Kiln. The rotary kiln is used to process the lead-containing components resulting from the breaking and separation of waste batteries. The main components of a rotary kiln are an inclined cylindrical, refractory-lined reaction shaft equipped to rotate over rollers and a burner.
