In the application of rotary kiln, it is most widely used in the cement industryt. The whole production process of cement can be summarized as "two grinding one burn", the" burn" refers to that the raw materials after ground and well confected will be firing to clinker under high temperature of the rotary kiln. Henan Daswell will tell the details of the feeding procedure of limestone rotary kiln:

1. Tell the site inspector stop the kiln slow rotating and separate the kiln from slow turning clutch, set the kiln at a speed of 0.4 ~ 0.5rpm and then start the kiln motor;

2. Close the entrance baffle of the high temperature fan, set the speed at 200rpm, start the main motor. When the fan runs smooth mobile crusher, you can gradually open the fan entrance baffle. And adjust the rotating speed of the fan based on the outlet pressure of pre-heater;

3. According to the wind pressure situation of the kiln hood, start the remaining fan of the cooling machine;

4. The first feeding of the rotary kiln should be 100t / h;

5. When feeding, the wind, material, coal changes greatly. You should notify the site inspector roll levels of flap valve to ensure the feeding smooth;

6. Notify the raw material system adjust the outlet fan baffle opening of the electric dust and ensure outlet negative pressure of the exhaust fan about - 150 ~ - 300Pa. And spray water when the kiln exhaust fan outlet...
