Active lime kiln system process description qualified limestone stored in silos, the lifting and transported into the pre heater top of the silo, pre heater top hopper, the bottom two materials position control feeding quantity, and then through the next feeding tube will be evenly distributed to the pre heater limestone calvary indoors.Limestone pre heater kiln flue gas is 1150c or so, about 30% of the decomposition, the hydraulic plunger push the rotary kiln, rotary kiln sintered limestone decomposed into cao and co2. Generated after decomposition of limestone into the cooler, the cooler was bubbled into the cold air cooled to 100 c at the discharge. The hot-swappable 600c hot air into the kiln and gas combustion. Exhaust fan in blended with cold air entering through the bag house, and then the exhaust fan into the chimney.The vibration of cooler lime feeder, chain bucket conveyor, bucket elevator, belt conveyor into lime finished products. Limekiln price according to customer requirements whether screening processes. Energy saving active lime kiln:technical characteristics:1) the installation of vertical pre heater kiln, kiln flue gas waste heat to make a direct transfer to the limestone flue gas temperature can be reduced to below 280c, electively recovered exhaust heat taken away, which also reduces the load for subsequent removal.2) by a conventional rotary aspect ratio is reduced to 20-25 to 14-15. Shortening the length of the kiln surface not only reduces the heat loss to the surrounding, the device also reduces the footprint.3) using the vertical kiln cooler cooling the materials to replace the original cooling tube, avoiding the lime sensible hear loss, failing from the hot lime kiln, with the drum into the secondary air heat exchanger, lime is cooled, the air absorbs heat into the rotary kiln temperature combustion .
