Pneumatic Conveying of Product Flyash Using FK pump

Posted in: , on 11. Sep. 2017 - 18:20

Dear Sirs,

Good Day!

We would like to convey flyash with our existing FK pump in dense phase. What is the maximum conveying rate for our pneumatic conveying system based on the data provided below.

Conveying Material Specification:

Material: Product Flyash (i.e. Grinded Flyash)

Median Particle Size: 12 microns

Bulk Density: 941 kg/m3

FK Pump Specification:

Model: M250

Screw Diameter: 250 mm

Design Capacity: 232 TPH

Outlet Diameter: 8"

Compressor Specification:

Model: Fuller C225

Differential Pressure: 1.66 Bar

Designed Capacity: 34.7 m3/min

Pipeline Arrangement

Pipe Diameter: 10" (i.e. Pipe diameter change from 8" at the FK pump oulet to 10")

Horizontal Distance: 300 m

Vertical Distance: 7.62 m

Number of Bends: 20

Any help on this would be greatly appreciated

Thank you!

Dear wilfredshu,

Your installation would perform approx. 70 tons/hr at a conveying pressure of approx. 1.5 barg.

However, there exists a wide range of fly-ashes.

Check with FLSmidt whether the FK pump, which you have, is suitable. (the right pitch ratio).

Also, do not underestimate the required FK-pump feeding system and the necessary controls.

Even better, ask your question directly to FLSmidt

Dear Teus,

Thank you for your help. Could you please explain how the pitch ratio of the FK pump screw would affect the conveying capacity of flyash?

Regards,

Wilfred

Dear wilfredshu,

The pitch, together with the rpm, sets the volumetric material flow

The pitch ratio controls the material compression to form the sealing plug.

Still better, ask your question directly to FLSmidt
