Gate rotary reduction kiln process

For reduction-reactions in rotary kilns, there are a number of such reducing agents; the more common ones being Hydrogen, Carbon, gaseous hydrocarbons and carbon monoxide.Ammonia and hydrogen sulfide are used, as well. Because the moving rotary kiln-tube requires a seal to the stationary material inlet- and outlet-housings, ensuring the reaction atmosphere can be a challenge
