Description: This series of rotary kilns is a large-scale calcination kiln with international advanced level jointly developed and researched by the company, Beijing Institute of Mining and Metallurgy, Changsha Institute of Mining and Metallurgy, Suzhou Institute of Non metallic Mineral Industry and other scientific research units. Compared with traditional kilns of the same specifications, this series of products has increased production by 30%, reduced heat consumption by 40%, and discharged flue gas temperature<250 ℃, making it easy to collect dust and meeting modern energy-saving, consumption reducing, and environmental protection requirements. Widely used in the calcination of products such as laterite nickel ore, active limestone, oxidized pellets, magnesium oxide, aluminum oxide, titanium dioxide, etc....

1. The design of the rotary kiln body fully considers the deflection support angle of the body, extending the service life of refractory bricks and castables. 2. Adopting large diameter and small aspect ratio idler bearings to improve reliability, the bearings are self-aligning bearings. 3. The new type of open gear cover sealing form has good sealing effect. 4. The laminated flexible seal of spring plates and the double-layer spring plate seal increase the insulation layer to improve reliability and service life.
