Abstract   

    The rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. The basic components of a rotary kiln are the shell, the refractory linings, support tires (riding rings) and rollers, drive gear, and the heating elements. Y&H has designed different solutions according to the needs of different customers. Y&H is particularly good at sintering powder and particles containing water and organic matter in products with relatively rich production experience.

WorkFlow

    The rotary kiln's tube is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its longitudinal axis(Controlled by a rotating motor). The process feedstock is using the screw feeder fed the upper end of the cylinder. As the kiln rotates, material gradually moves down toward the lower end and may undergo a certain amount of stirring and mixing. Using the electric resistance heating method to heating the materials, and once the process completed, the material can be discharged to the cooling section.

Rotary Kiln Working Principles

    Conveying materials of different properties through screw feeder (variable frequency control) into rotary kiln's tube, The rotary kiln itself will be installed with a certain tilt Angle(Maximum 5 Degree),As the tube rotates, the material will automatically fall into the tube and pile up at the end. Customers can make corresponding Settings according to their own heating process. The furnace will heat up by itself according to the parameters set. After heating up, the discharging operation can be carried out.If the discharge temperature is too high, the tail can be considered to add cooling section (water spray, or other cooling methods can be customized).
