a) 竖式预热器Vertical preheater：
①预热器采用带有低压降梁的低压降预热器，烟气在预热器中的阻力损失大大降低减少排烟设备动力消耗。从窑尾来的高温热烟气，直接穿过料层，与石灰石进行充分热交换，石灰石预热温度可达900℃，约有近30%的石灰石分解，排出的废气温度小于220℃。
The preheater adopts a low pressure drop preheater with a low pressure drop beam, and the resistance loss of the flue gas in the preheater greatly reduces the power consumption of the smoke exhaust equipment.The high temperature hot flue gas from the end of the kiln passes directly through the material layer for full heat exchange with the limestone. The limestone preheating temperature can reach 900℃, about 30% limestone decomposition, and the exhaust gas temperature is less than 220℃.
②预热器采用液压推杆向回转窑加料，设备运行可靠

③预热器顶部料仓设有料位计控制，保证预热器料层高度稳定
The top material warehouse of the preheater is equipped with material level gauge control to ensure the high stability of the preheater material layer；
④预热器除顶部采用吊挂砖外，其余部位均采用耐火浇注料，砖型少，砌筑简单
The preheater, except with hanging bricks at the top, adopts refractory pouring materials, with less brick type and simple masonry；
⑤预热器运动设备少，设备维护量小
Preheater movement equipment and less equipment maintenance。
b) 回转窑 rotary kiln ：
①采用直径较大、窑长较短窑型，节约占地
Adopt larger diameter and shorter kiln type to save land；
②传动设备采用变频调速电机驱动窑体，并设有辅助电机，工作稳定，调节灵活Transmission equipment adopts frequency conversion speed control motor to drive the kiln body and has auxiliary motor with stable operation and flexible adjustment；
