Re: Volume Of Air Required
It will be very difficult to split the conveying system as you suggest and it is not possible just to add additional gas to the pipe half way up to convey it the rest of the way.
You can probably use the onboard blower on the delivery tanker if you can accept a longer discharge time for the tanker, if not, you will really need to install a dedicated tanker offloading system from ground to the top of the silo.
The company who supply the tanker should be able to advise the offloading time for your full 32 m lift. There are many different types of tanker with different operating pressures and blower sizes so it is not possible for anyone in this forum to advise without more information. ■
Re: Volume Of Air Required
Gentleman, You can also go for the following systems --
1. Install a small hopper of 50-70 t on the ground
Feeding to this hopper shall be done by compressor of cement bulker .
Extraction from this steel silo to main silo shall be done by two methods--
1.By Pnuematically.
2. By Bucket elevator.

Re: Volume Of Air Required
Dear Mr Hayath,
Conveying cement to an elevation of 32 meters from a bulk truck into a silo is common practice.
If you can let us know the tank blower type and volume (m3/min and pressure) and the pipeline diameter and number of bends, then it is just a 1-minute calculation to determine the conveying rate.
Designing an alternative set-up is also no problem.
The effect of a half way booster can be made clear in these calculations as well.
Feel free to respond.
best regards

Re: Volume Of Air Required
Blower is piston compressor with 8 m3/min with 2 bar.
diameter of main conveying pipe is 4 inches.
2 no of 90 degree bends.
thank you ■
Re: Volume Of Air Required
Dear Mr Hayath Star,
Please note this summary of the various calculations of your bulktruck cement conveying system.
In the attachment you will find the capacity/pressure tables.
Summary:
pipeline 20 m vertical – 4”
compressor 0.1333 m3/sec (8 m3/min)
capacity 56 tons hr – 2 bar
pipeline 32 m vertical – 4”
compressor 0.1333 m3/sec (8 m3/min)
capacity 43 tons hr – 2 bar
pipeline 32 m vertical – 4”
compressor 0.1333 m3/sec (8 m3/min)
booster 0.1333 m3/sec after 20m vertical
capacity 38 tons hr – 2 bar
pipeline 20 m vertical – 4” and 12m vertical 6”
compressor 0.1333 m3/sec (8 m3/min)
booster 0.1333 m3/sec after 20m vertical
capacity 59 tons hr – 2 bar
pipeline 32 m vertical – 6”
compressor 0.2 m3/sec (12 m3/min)
capacity 88 tons hr – 2 bar
If further information is needed, we will hear from you.
success

thank you Mr.Teus for ur kind help.
it will be useful for me ■
Volume of air required
i want to convey the cement from the bulk tanker to silo top. The itself having a compressor, with that i can convey half the height of the silo (approx. 20 m). but now i want to convey it to the silo top (32 m) with external source. so how much volume of air at what pressure at what velocity i need? ■
