Active lime rotary kiln _ lime rotary kiln _ Ceramsite Rotary Kiln _ Metallurgical Rotary Kiln Why are there so many kinds of rotary kilns? What's their difference?

Lime rotary kiln: lime rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to building materials equipment. In recent years, with the implementation of national environmental protection policies and resource utilization policies, rotary kilns have gradually replaced earth kilns and vertical kilns with backward facilities, high pollution and high energy consumption. Rotary kilns can be divided into cement kilns, metallurgical and chemical kilns and lime kilns according to different materials. The medium temperature (950℃ ~ 1050℃) ceramsite rotary kiln calcination technology is mature and advanced in China, which represents the development direction of ultrafine kaolin calcination technology. This calcination technology has low energy consumption, high output, stable performance after dehydration, decarbonization and whitening, and can be used in industrial fields such as papermaking and coatings. Ceramsite rotary kiln has the advantages of long kiln life, high operation rate, stable operation, high heat transfer efficiency and low thermal efficiency. In the iron and steel metallurgical industry, rotary kiln is used for producing iron oxide pellets, direct reduction of iron concentrate, recovery and utilization of ultrafine iron concentrate and blast furnace ash slag.
