Rotary kiln process layout is not very reasonable, especially used in cement making production line and electric dust tail pipe have multiple ninety degree sharp turns, causing the great loss of flow resistance in pipeline, exhaust fan has high wind pressure but the blowing rate is reduced, causing that the wind pumping force of entire air system decreases. Especially the configuration of cement equipment, the un-reasonability causes air leakage, leading to the too low negative pressure in reveloving kiln. In order to ensure the stable operation of airflow within the system, we must take measures to stop air leakage. Otherwise the blower pumping power will increase, the air leakage phenomenon aggravates, power consumption and cost will be increased greatly, it is not conducive to solving node circle problem.
Let’s go on the question that how to operate it.
1. The first thing is how to watch the fire. The focus is on the flame profile, the length of the black flame tip, the brightness of the flame and weather it is smooth and powerful. You also need to watch the situation of the clinker grains, for instance, the height of the grain can be bring at, the flatness and thickness of the kiln shell in the clinkering zone.
2. To monitor the variables continually in the clinker rotary kiln, consisting of the temperature and the pressure in the kiln, the content of the oxygen and carbon monoxide, the complete system of thermal regulations. And make sure that all the fuel is complete combusted. All the clinker granulation shall be tiny and small as soon as possible.
3. When operate the process of the dry and wet types rotary kiln, you should consider both the situation of the clinkers in the predecomposition system and in the front end to avoid some unusual phenomenon, such as, big rise and fall, unsintered clinkers in the front end.
4. Keep the exhaust gas in a right temperature and will not fluctuate too much.
5. make sure that the circumgyrate kiln shell is complete and firm and no bad effects on its thickness.
6. f-CaO≤1.5%，litre weight is within ±50g/L
