Common Troubles
|
Causes
|
Trouble Shooting
|
|
1.No powder output or low powder output
|
1.Backward inhalation of the powder is caused by improper adjustment and bad sealing of the powder-locking device.
2.The spade is too worm out to handle the raw material.
|
1. Check and adjust the sealing of the powder locking device.Seal all the air leakage spots.
2.Replace the spade with a new one.
|
|
2.The finished particles are too coarse or too fine
|
1.The blades of the classifier are severely worn out without the classifying function.
2.The airflow of the blower in not proper.
|
1.If the particles are too coarse,replace the blades and adjust the blower to reduce the airflow of inlet.
2.If the particles are too fine,enlarge the airflow of the inlet.
|
|
3.The current of the main motor and the temperature of the machine go up while the current of the blower drops.
|
The material is fed too much that the air passage is blocked by powder.The airflow in the pipes is not discharged smoothly so that the heating of the circulating airflow makes the current of the main unit and temperature of the machine rise up and the current of the blower drop.
|
1.Reduce the quantity of feeding material and clean the accumulated power in the air passage.
2.Open the value of the residual air pipe and control the temperature of the feeding material below 6℃.
|
|
4.The main motor has loud noise and strong vibration.
|
1.The quantity of the feeding material is small or the main motor is not coaxial with the transmission device.There is no gap between two clutches.The ground bolts are too loose.
2.The raw material is very hard which results in strong impact,or there is no material layer.
3.The grinding rollers and ring are not so round or seriously deformed.
|
1.Regulate the quantity of feeding material,correct the coaxial grade,adjust the gap between two clutches.
2.Reduce the particle size of the feeding material.
3.Replace the grinding rollers and ring.
|
|
5.The blower vibrates.
|
1.Powder accumulates on the blades or the blades are worm out and not blanced.
2.The ground bolts are too loose.
|
1.Remove the accumulated powder on the blades or replace the blades.
2.Tighten the ground bolts.
