Rotary kiln is a calcining kiln, belongs to building material equipment. Rotary kiln can be divided into cement rotary kiln, metallurgy chemical rotary kiln and lime rotary kiln according to different processing materials. Cement kiln is mainly used to calcine cement clinker.

Following is the introduction of cement rotary kiln feeding procedures of Xixiang great wall corporation

1. Notice the scene inspection work to stop slow turning of rotary kiln, slow release the clutch, to set the kiln speed is 0.4 ~ 0.5 RPM, start kiln-owners' motor;

2. Close the high temperature fan inlet baffle, speed setting of 200 RPM, start the main motor, fan, smoothly operation, gradually open the fan inlet baffle, adjusting the rotational speed of the fans according to the preheater outlet pressure. When feeding the fan speed control is controlled in 450 RPM, preheater exit pressure is less than 1200 pa;

3. According to the kiln head cover wind pressure situation, start the cooling machines left the room fan;

4. The rotary kiln feed 100 tons per hour for the first time;

5. Release the wind, change of material, coal is bigger, inform the on-site inspection work in all levels of the flap valve, and ensure smooth when feeding material;

6. Inform the raw material system adjust the opening of electric dust collecting export fan damper, guaranteed kiln-owners' exhaust fan outlet suction - 150 - - 150 pa, when kiln-owners' exhaust fan outlet temperature reaches 200 ℃ + 10 ℃ for humidifying water tower;

7. After the clinker into the cooling machine, gradually increase the grate speed and grate cooler air volume, should be raised at this time two or three times the wind temperature; table rotary kiln hood negative pressure.

8. Kiln feeding stability, notify the diesel pumps, and extract oil gun.
