How to select the Roots blower for pneumatic conveying?

The air volume required in pneumatic conveying is determined by the conveying volume of materials and the mixing ratio of the feeder. The conveying volume refers to the weight of materials transported per hour, and the mixing ratio refers to the mixing proportion of materials transported and gas;

The calculation formula is Q=G/M ρ (Air volume Q is equal to conveying capacity G divided by mixing ratio M times air density ρ Product of)

In general, The greater the mixing ratio , the stronger the conveying capacity of the system , the higher the economy. Such as conveying materials Quantitative time , mixing ratio increases , which means transportation Company Quantity of material Air volume reduction , fan power decreases , pipe diameter And with it Smaller So that the system investment and Lower energy consumption cost; General:

The mixture ratio of low pressure conveying (below 50Kpa) is 1-10;

Medium pressure transmission (50Kpa-100Kpa): the mixture ratio of material and gas is 10-25;

For high-pressure transmission (100Kpa-700Kpa), the mixture ratio of material and gas can be as high as 40.

Pressure calculation method of pneumatic conveying fan

In pneumatic conveying, the pressure of the fan must be greater than the sum of all resistances when the material moves in the conveying pipeline. This resistance is also called pressure drop.

Generally, the most reliable way to determine the pressure required for the stable transportation of a certain material is to do material transportation experiments. The pressure drop of materials in 1m horizontal conveying pipe, 1m vertical conveying pipe and 1m conveying bend can be measured separately, and then the corresponding pressure drop can be calculated according to the actual length of the system. Finally, the total pressure required by the system can be calculated by adding the pressure drop of the unloader and dust remover.

If you do not do experiments, you can also estimate based on experience, but it is difficult to ensure accuracy!
