Introduction of dolomite calcination system

Dolomite calcination equipment is one of products of Henan Zhengzhou Mining Machinery Co.,Ltd., our company has for many years engaged in dolomite calcination equipment supply. The following is a brief introduction of dolomite calcination system. Dolomite calcination system mainly includes: raw material storage and transportation system; dolomite calcination system and flue gas treatment system. 1. Raw material storage and transportation system. Dolomite 15 ~ 40mm size shipped to the plant, stacked in the yard, yard operations using loaders. Particle size of the material by the loader will be loaded into the yard set by the material storage tank, under the material tank quantitative feeding by the feeder, the stone feeded to a large angle belt conveyor, to the top of the preheater silos. 2. Dolomite calcination system. Dolomite calcination system consists of vertical preheater, rotary kiln and cooling machine. Material from the top of the preheater silo through the feed chute into the preheater body, while the high-temperature flue gas from the rotary kiln will preheat the material to above 600 ?, make the dolomite partial decomposition, and then pushed by the hydraulic push rod followed by the tail kiln, after the rotary kiln calcined into the cooler though chute, calcined white cooled to a certain temperature and then discharge from cooler. 3. Flue gas treatment system. Rotary kiln combustion produce high-temperature flue gas, after the heat exchange with the dolomite in the preheater, the temperature dropped below 250 ° C, then into the bag filter, dust after the high-temperature fans into the atmosphere, the exhaust gas achieve the national emission standards.
