Our electrically heated indirect rotary kilns are a versatile solution for the thermal treatment processes up to 1050°C. Particularly effective for beta spodumene to lithium sulphate conversion, they support carbon footprint reduction and carbon capture ambitions in applications where process CO2 emissions are an issue.
Our indirect rotary kilns can handle a wide range of raw materials – from alumina and bauxite to vanadium salts, and many in between, including the highly effective treatment of beta spodumene in lithium processing applications, and the calcination of minerals up to 1050°C. We can deliver kilns from 1m to 20m diameter and up to 90m long. Lower-temperature units are available with natural gas heating in the event electric heating is not a viable option.
Product Description
Rotary kiln is a rotating cylindrical vessel which is used for drying, calcination and sintering in a continuous process with the use of hot gases. The hot gases may be generated in an external furnace or by a flame inside the kiln.Hengyang rotary kiln and sponge iron rotary kiln has been developed for performing drying, calcination and sintering work in a continuous process. Widely used for cement, pet coke calcination, dolomite, bauxite, sponge iron and other materials, it uses hot gases for the operation. Integrated with variable speed drive, process automation and instrumentation, this kiln ensures optimum operational control. In addition to technology, its design features better inlet and outlet sealing to ensure minimum false air entry.
