Preheater in cement industries

In cement industry, suspension preheater is a series of cyclones and pipe containers used to preheat raw meal. With the kiln material moving to lower stage, the temperature gradually increases. Almost every suspension preheater includes a calciner vessel where additional fuel is burned to support the calcination process
