Lime is a so widely used material for painting, food, fertilizer, for environment protection, and so on.
We provide full range of solution for lime, including crushing, grinding, calcination, hydrated and so on.
The qualified limestone is stored in the silo, lifted by the hoist and transported to the top of the preheater. The top silo of preheater consists of the upper and lower level meter to control the amount of feeding, and the limestone is evenly distributed to the preheater through the discharging pipe.
The limestone is heated to designed temperature, about 30% are broken down, then through the hydraulic putter into the rotary kiln, the limestone is decomposed into CaO and CO2 in the rotary kiln is by sintering . The limestone generated after decomposition is into the cooler, and then is discharged out of the cooler by its temperature is cooled to about below 100 °C.
The 600 °C hot air by heat exchange into the kiln to burn mixed together with gas. The waste gas with cold wind is into bag filter through the induced draft fan and then into the chimney by the exhaust fan. The lime out of cooler is into the finished product silo through the vibrating feeder, chain bucket conveyor, bucket elevator, tape conveyor. The screening process is based on customers’ requirements.
