Dear a5386445,

Your question what is the max distance i can blow the cement ? seems not relevant, because you also give the distance (70 m).

To answer your question, the maximum length you can convey cement with your compressor is estimated at approx. 4 km with a capacity of 1 ton/hr.

Probably, you are more interested in the conveying rate of the VM75 at a distance of 70m and which pipeline diameter.

Let us know. ■

Dear a5386445,

The first question is:

How much cement can be fed by a Fuller Kinyon pump DN200 into a pneumatic conveying line? The FLS website is not providing this information.

Keep in mind that the FK pump (probably a FK M200) has an 8” outlet.

The VM75 is a too big compressor for the 8" FK pump.

The VM75 is also a too big compressor for a 12”pipeline. (a 14” pipeline at 2.1 barg is more suitable)

The combination VM75 and FK M200 might require a FK pump air by pass arrangement, which is not easy to control with only one compressor.

This question can be assessed, when the 1st question is solved.

Have nice day

Dear a5386445,

Preliminary calculation result:

L-horizontal = 55m

L-vertical = 15 m

Number of bends = 3

Compressor: Aerzen VM 75 = 93.6 m3/min

Feeder: FK pump M250 = 180 tons/hr at 2.1 bar (??????)

Compressor pressure = 0.82 barg

Pressure drop FK pump M250 = 0.187 bar

The calculated maximum conveying length is estimated at approx. 380 m (L-hor= 335 m, L-vert = 15 m)

Compressor pressure = 2.1 barg

Pressure drop FK pump M250 = 0.143 bar

Remark:

A FK pump requires a controlled feed into a surge hopper with filter above the screw pump intake.

This is to prevent stalling of the screw pump.

The drive motor must be capable of starting in Delta.

Notice that the above figures are an indication only.

Is the equipment in good condition and what is your perception of efficient?

Take care ■
