Cement and Lime Kilns AMETEK PROCESS INSTRUMENTS

网页Kilns are normally fired with pulverized coal or gas at one end. Raw materials are fed to the kiln at the back end, furthest from the burners. Travelling through the kiln, the ingredients are progressively heated. Here, flue gas flows in the opposite direction. The kiln can be divided into three zones drying, calcining and burning.
