The vertical preheater is one host device of the active lime production line ,and its main function is to send lime stone from the upper hopper to the body of the preheater ,while using high temperature exhaust gas (**0℃****0℃) discharged from the calcinations kiln to make heat exchange, and then preheat the materials evenly into above **0℃ in the preheater. after preheating ,there is *0% CaCO3  will be broken down and then puushed into rotary kiln for burning by the hydraulic push rod.so such a calcinations process not only shorten the time of lime stone burning in the kiln ,but also can get a high activity degree of lime.our company adopts LDO vertical preheater, and compared with ordinaty preheater, it reduces the loss of flue gas resistance and the power of smoke ventilator greatly, it saves the energy consumption .besides , it features few running equipments easy operation, little maintenance,simple masonry and reliable performance.
