Rotary kiln is widely used in building materials, metallurgy, chemical and other industries for magnetizing roast of lean iron ore and oxidizing roasting of chromium, nickel and iron ore. Rotary kiln blockage will have a serious impact on normal operation of rotary kiln. Hongxing Machinery offers you some tips for preventing clogging of rotary kiln.

1. Make a systematic check before opening the kiln. After the overhaul of preheater system, please be sure to conduct a thorough and careful examination of the system and clean up the pipeline. Check whether the preheater liner is intact and solid. Inspect the ash valve step by step and guarantee the rotation is flexible.

2. System seal. Seal all inspection doors, flanges, and ash valve shaft tightly to prevent leakage of wind. Please pay attention to the seal of inspection door after dealing with congestion.

3. Make stable operation and strengthen the sense of responsibility. In the normal production process, operator need abide by the rules, regulations and operating procedures to maintain a reasonable temperature and pressure distribution. Feed and reduce raw material in time. Feeding amount synchronizes with the kiln speed. When you are forced to reduce the material because of lack of materials or other reasons, please do not reduce down the exhaust air substantially to prevent the formation of material accumulation. The operator need make regular inspection, contact and observation.

4. Improve the quality of raw material and fuel. Guarantee the uniform and stable raw materials and fuel element. Adopt high quality ingredient and adjust clinker modular value to keep the liquid phase amount in 24-27%. Keep the coal power fineness to about 10% and moisture of coal power to about 1.0%. Avoid the usage of low quality coal and high sulfur coal.
