NEW Building Material Machinery Rotary Kiln Cement Production Line Introduction:
Rotary kiln cement production line is a preprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary kilns include: Cement, Lime, Refractories, Metakaolin, Titanium dioxide, Alumina, Vermiculite, Iron ore pellets, etc. Rotary kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burnerpipe (or "firing pipe") which acts like a large bunsen burner. The fuel for this may be gas, oil or pulverized coal. Rotary kiln is often compared to an industrial sized oven which is designed to withstand extreme temperatures as needed for the smelting process of all types of hydraulic cement.
