回转窑
三档回转窑
●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.
两档窑
●静定结构，支承受力分配合理；
Statically determined structure ensures even distribution of forces onto the twoe supports;
●筒体表面散热少，降低系统热耗
Less heat dissipation on the shell surface to reduce the heat consumption of the system.
●单位截面热负荷低，耐火砖消耗显著降低；
Low heat load per unit cross-section, low consumption of refractory brick;
●设备可靠性高，避免机件超负荷；
High equipment reliability by avoiding mechanical overload;
●占地省，建设投资低；
Minimum space requirement, low investment in land acquisition and civil works;
●检修维护费用低；
Low maintenance costs.
