What should we do if something goes wrong with a sand dryer? We have brought you several methods for your reference.

  • Raw materials cannot be dried at one time

1. The dryer is too small to increase the drying temperature, but it is easy to cause fire in the dryer. The best way is to replace or modify the drying equipment.

2. The calculation of air pressure and flow of air network is wrong; the manufacturer is required to calculate the air pressure and flow again, and then provide the design change scheme according to the actual situation.

3. Improper use of the dryer; learn the correct use method according to the operation manual of the dryer.

  •  Explosion of sand dryer

1. If the drying temperature is too high, it will cause fire and combustion in the dryer, and reduce the drying temperature.

2. The drying equipment is blocked; clean up the drying equipment.

  • The finished material can not be discharged normally after drying

1. If the drying equipment is installed improperly, there is air leakage or wrong installation; check whether the installation is correct according to the installation drawing, and check whether there is air leakage at the four joints of the pipe;

2. Drying equipment design problems, air pressure is not enough.

  • Raw material in sand dryer catches fire

1. Improper use of sand drying equipment; learn the correct use method according to the operation manual of dryer equipment.

2. If the drying equipment is too small to achieve the drying effect, forced heating causes fire; replace or transform the drying equipment.

3. There are some problems in the design principle of drying equipment, and the manufacturer is required to replace or transform the drying equipment.

4. If the raw material can not be absorbed, it will cause fire in the dryer; check whether the drying equipment is installed correctly, whether there is air leakage or increase the air pressure.

  • Due to uneven drying and wetting of materials, the front bar making can not operate normally

1. Improper use of sand dryer equipment; learn the correct use method according to the operation manual of the dryer.

2. Raw materials are agglomerated (for example, raw materials are thawed in northern winter); raw materials are crushed and then dried.

  •  Drying equipment wastes fuel

1. The heat preservation performance of the equipment is poor; a layer of thermal insulation material is wrapped to improve the working condition of the drying equipment.

2. There is a problem in the design principle of the equipment; consult the furnace drawing.

3. Furnace design and production problems; consult furnace drawings.

I hope the above information can help you.
