●合理优化回转窑筒体跨距分布和钢板厚度，减少筒体的弯曲和变形；
Kiln span distribution and steel plate thickness are carefully designed to reduce bending and deformation of kiln shell.
●采用大直径小长径比浮动托轮轴承，提高可靠性
Kiln support rollers are equipped with floating roller bearings with large diameter and small L/D for higher reliability;
●选用分段大齿圈或两半调质大齿圈，大幅提高齿面硬度，减少齿面磨损和变形，提高齿圈寿命，迷宫结构的齿轮罩，可
有效提高密封性能避免漏油问题；
The segmented girth gear or two-half quenched and tempered girth gear is selected to greatly improve the hardness of the gear
surface, to reduce the wear and deformation of the gear surface, and improve the service life of the girth gear. The gear cover with
labyrinth structure can effectively improve the sealing performance and avoid oil leakage;
●改进窑内耐火砖的配置，降低筒体表面温度，延长火砖使用寿命；
Improve the configuration of refractory bricks in kiln, reduce the surface temperature of kiln shell and prolong the service life of
refractory bricks
●窑头密封采用带轴向迷宫的结构和复合密封叠片，内部增加两道反向密封叠片，大幅提高密封性能；
The kiln outlet seal adopts the structure with axial labyrinth and composite seal lamination, and two reverse seal laminations are
added inside to greatly improve the sealing performance.
●窑尾密封采用重锤压紧或气缸压紧摩擦圈结构，摩擦片之间加入润滑脂，密封效果好，操作维护简便，使用寿命长。
The kiln inlet seal adopts the structure of heavy hammer compression or cylinder compression friction ring. Lubricating grease is
added between the friction plates, which has good sealing effect, simple operation and maintenance with long service life.
