Causes of various problems in slime dryer
- The life of internal wearing parts is short.
Cause: the internal material selection is not good, cutting corners, will lead to parts damage more easily, shorter service life.
- Due to the uneven drying and wetting degree of materials, there is no way for the bar making to work normally.
Reasons: ① improper operation of dryer.
② Raw materials are agglomerated.
- After the dryer manufacturer dries the materials, the moisture content must exceed the required value.
Reason: according to the production capacity, and the matching heat is not enough.
Troubleshooting: increase the furnace temperature and reduce the amount of feed.
- The final moisture content of the material dried by the dryer is less than the specified value.
Cause: too much heat supply or too little wet material feeding.
Solution: strengthen the feeding quantity of wet materials and reduce the amount of oil supply, gas supply or coal supply.
- The lower sliding material basin and air inlet pipe are easy to be blocked.
Reason: the matching furnace type is not suitable. High temperature boiling furnace can be used to change the air inlet mode.
- In the process of using, the sliding material basin on the upper part of mine dryer is easy to block.
Causes: 1) high initial moisture content
② The material is viscous
③ The layout of secondary air duct is unreasonable.
- The separator is too small.
Solution: replace or transform the separator.
