ertical Preheater Introduction：
The vertical preheater is one host device of the active lime production line, and its main function is to send limestone from the upper hopper to the body of preheater, while using high-temperature exhaust gas (950℃--1100℃) discharged from the calcinations kiln to make heat exchange, and then preheat the materials evenly into above 900℃ in the preheater. After preheating ,there is 30% CaCO3 will be broken down and then pushed into rotary kiln for burning by the hydraulic push rod .So such a calcinations process not only shorten the time of limestone burning in the kiln, but also can get a high activity degree of lime.
Our company adopts LDO vertical preheater, and compared with ordinary perheater, 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.
