Limestone rotary kiln calcination system

Lime rotary kiln is a one of rotary kilns, its production and development mainly based on limestone raw materials. The active limestone rotary kiln system was developed on the basis of the development of limestone rotary kiln production, which requires a higher technological requirement and more conducive to the development of rotary kiln technology.
Lime production line process is: qualified limestone stored in the silo, from the upper and lower 2 level meter to control the amount of feeding, and then through the pipe to the limestone evenly distributed to the preheater each room. Limestone in the preheater was 1150 degrees Celsius kiln smoke heated to 900 degrees Celsius, about 30% decomposition, the hydraulic putter into the rotary kiln, limestone in the rotary kiln by roasting into Cao and CO2. After the decomposition of lime into the cooler, in the cooler was sucked into the cold air cooled to 100 degrees Celsius below discharge. The heat exchange of 600 degrees Celsius hot air into the kiln and gas mixed fuel. Exhaust gas and then into the cold air by the fan into the bag filter, and then discharged into the chimney by the exhaust fan. The lime discharged from the cooler is fed into the lime reservoir by vibrating feeder, chain conveyor, bucket elevator and belt conveyor. According to the user needs to determine whether the screening process.
In the whole lime roasting system, the preheater is divided into several preheating chambers according to the output. Each preheating chamber is equipped with a hydraulic push device and equipped with automatic control system to transmit the relevant data to the PLC control platform of the central control room, to achieve centralized control. This system has a high degree of automation, can achieve a single point of control, the production process more convenient.
We pay attention to the system balance in the process, the system leaks and other aspects of the improvement, so that the ratio of materials and fuel more reasonable, reducing the fuel energy loss, saving investment.
The active limestone system has contributed to the development of limestone and the development of rotary kiln technology. Today, the effective usage of new technologies and equipment in the construction industry has become the basis for the development of competition among major enterprises. Active limestone rotary kiln system will also continue to develop, and expand its application.
