In recent years, the rapid development of lime kiln industry, China's metallurgical technology regardless of lime production in the equipment, or the scale of energy consumption or products have entered a new stage of development. Nickname roller kiln lime kiln, advanced structure, low loss vertical preheater can effectively improve the preheating effect preheated limestone kiln decomposition rate of up to 20-25%, and the direct use of 10-15mm fine grade limestone; rotary lime kiln reliable modular scales sealed at both ends The leakage coefficient is less than. 10% use of composite refractory material to reduce radiant heat loss; lime kiln filled, can be partitioned ventilated round or square vertical cooler, Cone crusher     resorted to the cooler temperature of 800C + lime ambient temperature, easy transportation, storage, and secondary air into the kiln will be heated to 7000C or more, reducing the moving parts and special materials. Henan YuFeng Heavy professionally built lime kiln, the company's technical staff painstaking research on the lime kiln to be improved step by step, making it very prominent advantages, for lime kiln drying kiln firing system, the ignition system is to be put into the kiln drying The key aspects of the production, so it should be fully prepared. For roasting and feeding system for all devices, including preheater, rotary kiln, such as no-load single normal operation and adjust it to start the work of the state, the fuel supply device is working properly and can in front of the fuel to the kiln to ensure preheat, coolers, and other equipment safe operation of auxiliary systems such as compressed air, lubrication systems should be put into normal operation in advance. In the stand-alone test process, pay attention to the drag operation shaft lime kiln temperature changes and wear, the bearing temperature does not exceed 60 degrees. In the liner preheater most castable refractory, the process of drying kiln flue gas contains a lot of water, so the process of lime kiln gas kilns generally be discharged through the bypass, without passing through the baghouse.
