Re: Cement Pneumatic Calculation
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. ■

thanks for your interest mr Teus
i need to know what is the maximum length of pipe that i can transfer cement on the ship.
it is an existing system old one that iam not sure if it going to be efficient
pipe diameter=12inches
what should i calculate?
best regards ■
Cement Pneumatic Calculation
okay i was not correct before
i want to blow cement on a rate 180tonnes/hour through the below:
i have an aerzen VM 75 400kw DN200 and FK PUMP 180MT/HOUR
Flow at inlet : 93.6m3/min
press diff: 2.1 bar
motor speed = 2950
inlet pressure = 1 bar
12 inches pipe
IS IT POSSIBLE TO TRANSFER CEMENT WITH 160-180MT/HOUR ?
WHAT IS THE MAXIMUM LENGTH I CAN TRANSFER CEMENT ON THAT RATE?
THANKS ■
Re: Cement Pneumatic Calculation
Dear a5386445,
The first question is:
IS IT POSSIBLE TO TRANSFER CEMENT WITH 160-180MT/HOUR ?
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.
WHAT IS THE MAXIMUM LENGTH I CAN TRANSFER CEMENT ON THAT RATE?
This question can be assessed, when the 1st question is solved.
Have nice day

okay Mr Teus
i will come back tomorrow with all the details of the existing system design
thanks so much for evwrything so far ■

what should i calculate?
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.
it is an existing system old one that iam not sure if it going to be efficient
Is the equipment in good condition and what is your perception of efficient?
Take care ■

dear sirs
good day
i have an aerzen VM 75 400kw DN200
Flow at inlet : 93.6m3/min
press diff: 2.1 bar
motor speed = 2950
inlet pressure = 1 bar
whats the max distance i can blow the cement ?
horizontal distance: 50mtr
vertical : 15 mtr
horizontal = 5 meters ■
