Rotary Kiln – IspatGuru

Dec 26, 2019 · Rotary kiln sizing and design. Every material is different in terms of how it behaves in the kiln and at what temperatures different reactions are going to occur. When designing a process around a rotary kiln, as well as in the design of the kiln itself, the material is required to undergo thorough chemical and thermal analyses.
