Working principle of rotary kiln: 1) With a certain slope to the level, the whole kiln body is supported by rollers and fitted with thrust rollers to control up and down movement of the kiln body. 2) Besides main driving unit for driving system, it is also fitted with the auxiliary driving unit so as to ensure the kiln body still can rotating when the main motor is powered off and prevent it from deforming. 3) The kiln head adopts housing type sealing and kiln rear uses axial contact sealing unit so that reliability of sealing could be ensured. The advantages of rotary kiln: The kiln has advantages of reasonable structure, high efficiency, low energy consumption and convenient for transportation, and convenient and reliable operation; Therefore, the consumption of the coal and the electricity is lower than the common ones. While the production capacity is higher than ****5%. Structure Features of Rotary Kiln: The kiln shell is made of rolled steel plates; its structure is optimized by computer software, and features" longitudinal flexible and transverse rigid”, which improved the loading of supporting device and stability of refractory lining, The supporting roller bearings features smaller width over diameter ratio L/D, leading to its higher reliability. The special high-started torque motor for cement industry rotary kiln is applied for driving system. The sealing of labyrinth plus spring pressing with asbestos heat isolation layers attached, is applied higher so that reliability and longer service life of sealing are achieved.
