  • Rotary kiln

    Rotary kilns (sometimes called calciners or rotary furnaces) are used for thermal treatment processes such as calcination, sintering, pyrolysis and firing, as well as for oxidation and reductionThese treatments can be applied to powders, granulates, suspensions and green bodiA rotary kiln consists of a cylindrical, rotating body mounted between stationary material feed and outlet housings...

  • Moisture Reduction in a Rotary Kiln

    Although rotary kilns are designed to be used for driving a chemical reaction, an issue that often comes up in the processing of a material is when to draw the excess moisture from the feedstock Many times, there is an excess of moisture that needs to be removed from the material before it is converted in the rotary kiln,...
