How to choose the induced draft fan for coal slime dryer ?

Time:2020年06月12日      Hits:

Induced Draft Fan is an important equipment in the coal slime dryer, which can help the coal slime dryer to complete the drying task smoothly. For materials such as coal slurry with strong viscosity, the induced draft fan plays a great role, so how to choose the induced draft fan of the coal slime dryer?

First of all, we need to determine the capacity of the induced draft fan according to the moisture that needs to be evaporated by coal slurry dryer, and make sure the model can meet our production needs.

Secondly, we need to select induced draf fan according to the production capacity of the coal slime dryer itself. When we purchase the equipment, we will determine it according to our production demand. So when we purchase the induced draft fans, we need to determine the air volume and air pressure of the fans according to the production capacity and resistance of the coal slurry drying system. Here, we need to pay attention to whether we use single or double fans, their total pressure state is greater than the resistance of the coal slime drying system itself.

It is also necessary to note that the temperature of the induced draft fan cannot change too much. When selecting the fan for the coal slime dryer, the manufacturer will tell you the designed temperature of the draft fan. We need to pay attention to this temperature range when using the fan. If the temperature is too high, it means that the fan motor is running under overload, and the body will burn the motor if it is serious.
