At Hengyang, 16 different rotary kilns are available for your projects, trials and production needs, giving you a full range of size and configuration options. This diverse spectrum of equipment is designed to be as versatile and adaptable as possible – as such, Hengyang can offer clients almost any degree of thermal treatment necessary for project completion.

How Rotary Kilns Work

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 reduction. These treatments can be applied to powders, granulates, suspensions and green bodies. A rotary kiln consists of a cylindrical, rotating body mounted between stationary material feed and outlet housings. The constant turning of the kiln body mixes the material, ensuring that it is processed homogeneously. Rotary kilns are heated either directly (inside the kiln chamber) or indirectly (from outside), depending upon the requirements of the application.
