Rotary kiln is a type of rotary cylinder equipment. Mainly divided into oxidation pellet rotary kiln and metallurgical rotary kiln.The structure includes the supporting device, the cylinder body, the transmission device, the head and tail sealing cover, the structure cooling device, the head and tail sealing device and other parts.The rotary kiln designed and produced by our company has a maximum diameter of 8.28 meters and a maximum length of 165 meters. It has the characteristics of advanced structure, low failure rate, low energy consumption, and convenient maintenance. It is widely used in the non-ferrous metallurgical industry (such as alumina roasting, copper oxide reduction, Zinc oxide reduction, arsenic removal from tin concentrate, nickel-iron reduction roasting, tungsten concentrate calcination, pre-reduction of ferrochrome pellets, titanium dioxide roasting, kaolin roasting, etc.), ferrous metallurgy industry (such as poor iron ore magnetization roasting, blast furnace ironmaking Pellet roasting, direct reduction of pellets, etc.), chemical industry (such as acidification roasting of lithium carbonate, calcination of carbon products, etc.).
