Re: Pneumatic Conveying Challenge
Yes it can be done. You have not mentioned the conveying rate.
Depending on the conveying rate blower size will need to be calculated. ■
Re: Pneumatic Conveying Challenge
Thank you Mantoo.
The nominal rate we need is 30 tph considering the carbon around 1.25 t/m3
My concerning is the risk of clogging due to variability of grain size.
Do you have some tip for this application? ■
Re: Pneumatic Conveying Challenge
This is a typical screw conveyor application. Can easily be done by two screws. First question is why you want to use pneumatic conveying. If the answer is no space for screws then I can understand.
If you want to go for pneumatic conveying then I would recommend lean phase vacuum conveying. Size for 18 m/s pick up in 6" pipe with 200 mbar dp on exhauster. Size distribution will be fine for occasional 30 mm lumps. ■
Re: Pneumatic Conveying Challenge
Thanks very much for your tips,
First of all ve have to discharge in an air lifter working at 1 bar.
Furthermore yes we have not so much room to use screws. ■
Re: Pneumatic Conveying Challenge
If you require discharge against 1 barg pressure you can still use a vac system and use a
Rotary valve as an airlock and then a screw to discharge into the airlift.
If you want to go for positive pressure then you will need a min 1300 mbar dp on the blower
compressor. ■
Pneumatic Conveying Challenge
Hi all,
I would like to know if it is possible to convey a mix of fine and coarse carbon with a pneumatic system.
The size of granules is up to 30 mm but 75% is less than 5 mm.
The distance to reach is about 12 m with only 1 elbow and I intend to use a 6" pipe at 1 bar.
Then it will be discharged in a airlift.
Basing on your experience, can be possible to arrange a relliable system for this purpose?
Thank you ■
