1.At first,you should leran how to watch the internal fire of rotary kiln.including the flame profile, the length of black flame head,flame brightness and whether the flame is smooth and forceful, to see clinker grain,take feed height and rolling condition and how much incoming materials,to see the flatness and the thickness of kiln leather .this is the first question of rotary kiln operation.

2.keep watch on rotary kiln and tempreture of predecomposition system and pressure change,the O2 and CO content in waste gas and thermal regulation change of entire system.make sure fuel to complete combustion, reduce the yellow center material.try to make the clinker grain Small uniformity,reach the fineness of rotary kiln discharging.

3.to operate predissociation rotary kiln stick to give consideration to two or more things,take consider predissociation system condition in connection with rotary kiln head clinkering zone condition, to improve the rotary kiln rotating rate.in theoperation, be cautious of big rise and fall, top fire forced burn,strictly prohibit escape raw or stop dry burning of rotary kiln.

4. strictly control fCaO content under 1.5% inside rotary kiln,litre weight wave range with 50g/L.

5. within the premise of ensuring rotary kiln clinker production quality，keep proper waste gas tempreture,,reduce the wave range and fuel consumption.

6. make sure conpleteness and firm of rotary kiln clinkering zone kiln leather, thickness uniformity,firmness.make an effect to protect rotary kiln liner when operating, extend the period of safe handling.
