rotary kiln used for calcination nickel ore

About this site

Nov 15, 2020  Coal is used as a common fuel for calcination of nickel laterites in rotary kiln. Due to the depletion of high-quality coal with low impurity content, high-sulfur coal has been used as fuel in nickel laterite rotary kilns. This investigation examines the behavior of sulfur present in the rotary kiln fuel in the calcination stage.
