Description
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 calcination 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 calcination process not only shorten the time of limestone burning in the kiln,but also can get a high activity degree of lime.
