The limestone is back to the rotary kiln brick kilns, its production and development mainly with limestone and raw materials. The rotary kiln system is in active limestone limestone rotary kiln production based on the development of the invention of the research, the system of the technology request higher, and can promote the development of the technology of rotary kiln.

The process of the production line is: qualified limestone mandibles crusher stored in the warehouse inside, consists of two material location control and shoes, and then through the feeding tube will limestone evenly distributed to preheater each room. The limestone is 1150 degrees Celsius in the preheater kiln gas heated to 900 degrees Celsius, about 30% decomposition, the hydraulic push the push rod in rotary kiln, limestone in rotary kiln roasting decomposition theory for CaO and CO2. Decomposition generation into the cooler lime, in cooler in the cold air cooling drum to 100 degree Celsius eduction. The heat to 600 degrees Celsius heat of air into the kiln and the mixed fuel gas. The cold wind confirmed by waste gas again into the bag filter induced fan, then the drained to the chimney. Discharge of the cooler the lime vibrating feeder, chain conveyor and fight a pattern lift machine and belt into the lime library. According to the needs of user to determine whether screening process classification.

In the whole lime roasting system, preheater according to yield divided into many different preheating room, lime rotary kiln each room is equipped with a hydraulic preheated push mixture device, sand and magnetic separation machine is equipped with automatic control system will be transported to the relevant data of the central control room PLC control platform to realize the central impactcrusher centralized control. This system is a high degree of automation, may realize the single point controllable, make the production process more convenient. We in the process on attention system balance, in the air leakage system improvement, make the material and fuel ratio more reasonable, reduce the fuel energy loss, save investment.

Active limestone systems to the development of limestone and rotary kiln technology development with the power, in the construction sector development today, effective use new technology and equipment has become each big enterprise competition between the base of development activity limestone rotary kiln system also will once again continue to develop and expand their application scope.
