Handling of abnormal conditions of Cement Manufacturing Process Machine
Cement Manufacturing Process Machine vibration is too large
1. The feeding is uneven or too small. When the slag is milled, the time is large and small. When the difference is large, the thickness of the upper layer of the grinding disc is uneven, and even the grinding roller hits the damper, resulting in grinding. The solution is to stabilize the amount of material to be milled, adjust the feeding speed or reduce the operating pressure, and appropriately reduce the speed of the powder separator under the premise of ensuring the specific surface area of the material.
2. The metal object enters the Cement Manufacturing Process Machine to check whether the metal detector and the drum separator work normally. Increase the iron removal device of the feeding and feeding system and material circulation system to reduce the metal ingress.
Cement Manufacturing Process Machine production capacity is too low
The possible reasons are:
1. Low drying capacity;
2, low grinding pressure;
3. The specific surface area of the product is too high;
4. The system has a low air volume.
The solution is to increase the heating capacity of the hot blast stove under the premise of ensuring the feeding capacity, increase the grinding pressure, reduce the speed of the sizing machine, and increase the exhaust volume of the system.
When it is found that the feed bin is insufficient, it should be stopped. If there is any danger of dry grinding after continuous operation, the Cement Manufacturing Process Machine should be stopped to feed. After the feed is sufficient and stable, the feed will be run, otherwise the bed will be thinned. The Cement Manufacturing Process Machine vibrates and damages the reducer. However, the temperature of the Cement Manufacturing Process Machine must be controlled to prevent the dust collector from burning the bag due to the temperature being too high.
Cement Manufacturing Process Machine pressure difference is too big or too small
When the pressure difference is too large, the feed should be reduced immediately and the differential pressure indicating device should be observed. Check for possible causes:
1. The feeding device is faulty and the feeding is excessive;
2. The squeezing hole of the grinding disc is blocked;
3. The air volume is too low or unstable;
4. The fineness of the adjustment of the classifier is too fine.
The reason why the pressure difference is too small:
1. The feed amount is too low or the feed is interrupted;
2. The fineness of the product is too thick;
3. The ventilation capacity is too strong.
Also check that the pressure gauge is working properly.
System temperature is too low
The entire system should be inspected immediately to check for possible causes:
1. The feed amount is too large or the material is too wet;
2. The heating capacity of the hot blast stove is reduced;
3. Each control valve is out of order or inaccurate.
Conversely, if the system temperature is too high, it should be checked accordingly. And deal with it accordingly.
System operating pressure drop
1. Whether the oil pipe leaks;
2. Whether the pressure control solenoid valve is malfunctioning or damaged;
3. Whether the pressure pump works normally;
4. Whether the pressure switch is abnormal or not, and whether the pressure gauge is normal.
If the above equipment is in good condition after inspection, the pressure pump can be restarted at this time. If the pressure is normal after the pressure pump is turned off, there is no need to stop the machine. Otherwise, the machine will stop and check to eliminate the fault before starting the machine.
