Structural features

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. In addtion, the sealing type for housing of set girth gear and pinion is optimized.

The sealing of labyrinth plus spring pressing slices with asbestos heat isolation layers attached, is applied at higher reliability and longer service life of sealing are achieved.
