Wet rotary kiln, as building material equipment, is widely used in metallurgy, chemical industry, building refractory material, environmental protection and other industries. The rotary kiln consist cylinder, supporting device, support device with retainer wheel, drive device, active kiln head, kiln end sealing device, coal injection pipe device and other components. Wet rotary kiln body shows a certain degree of tilt to horizontal level. The entire kiln body is supported by roller device. It also has retainer wheel device to control the kiln body in case it runs up and down. The drive system also has auxiliary drive that can make kiln body drive when major power is off and prevent kiln body bending and being out of shape besides major drive. Kiln head and kiln end sealing device uses advanced technology to ensure reliability of sealing. |

Rotary kiln body is rolled by steel plate, with refractory lining inside and shows a certain degree to the horizontal level. Each block support device is supported by three wheel belts. Fix a gear ring in the inner cylinder around feeding wheel belt with cutting spring plate. There is a meshing pinion under it. When operating normally, transmit power to open gear device from main drive motor to main reducer to drive rotary kiln. |

This series of rotary kiln is the large-size advanced international calcining kiln and furnace which is developed by our company and many scientific research institutes such as Beijing General Research Institute of Mining and Metallurgy, Changsha Research Institute of Mining and Metallurgy, Suzhou Sinoma Research Institute of Non-metallic Mining Industry, etc. Compared with the rotary kiln with the same specification made by the traditional technology, this series of rotary kiln can make the production capacity increase by 30%, make the heat consumption reduce by 40% and make the discharged flue gas temperature <250℃, so it is convenient for collecting dust and meeting the modern environment protection needs about energy saving and consumption reducing. This rotary kiln is widely used for extracting nickel from laterite, calcining the activated limestone, oxidized pellet, magnesium oxide, aluminum oxide, titanium dioxide, etc. |

Jiangsu Pengfei Group independently developed rotary kiln system. In 2003, Pengfei got two patents. In 2006, Pengfei cement kiln was named "China Building Material Machinery Industry Famous Brand", "Jiangsu famous brand". In 2007 it won the "China Famous Brand" products title. On this basis, Pengfei Group and Southeast University, Yancheng Institute of technology jointly developed ---- cement kiln disposal of industrial waste and municipal solid waste technology and equipment. Large-scale rotary kiln intelligent control systems and rotary kiln waste heat power generation and integrated development use issues was borne by the Southeast University; preheater cyclone separation efficiency and low resistance, the use of precalciner burning garbage research topics was undertaken by Yancheng Institute of Technology. The project is applied to high energy saving calcined cement industry and use biomass from waste incineration as an auxiliary heat source. Also it can incorporate garbage to achieve circular economy. It is mainly used in daily output of 5,000 tons clinker of a large dry-process cement production line, and it can also be applied to energy-saving renovation of small and medium cement burning system. |
