Activated Carbon
We have several systems conveying this material in the field. We commonly use atmospheric air to provide conveying media. Must use vacuum system as the material is very dusty and will tend to blow out of any creivise. Material will become extremely fluidized after conveying making bulk density go way down. Proper size of blender volume must be taken into account. Filter media as well as type plays an important role in keeping dust from clean air plenum. This material is manageable, however application requires several unique handling methologys to make system run reliably. Call on us if you need help with this.

Re: Activated Carbon Pneumatic Conveying
Dear Mr. Amir manoff
If you need a very safe system, you can use inert gas in a completely closed system + explosion rate equipment. We can provide the whole system backed by over 32 years of solid experience. Please visit out website www.cyclonaire.com

Vacuum Conveying Of Activated Carbon
Dear Mr. Amir Manoff,
The best way of moving activated carbon is in my opinion Vacuum
Conveying.
Depending on the following parameters usually it is not necessary to convey it under an inert gas:
Total Conveying distance: (m)
Conveying height: (m)
Bulk density: (kg/l)
Particle size distribution: (microns/mm)
Desired throughput: (kg/h)
Estimated Flowing Characteristic:
With these parameters first the right size of conveying system
is selected and then a decision can be made.
Under www.Volkmann.info you will find a huge range of different
Vacuum Conveying Systems, all ATEX certificated by the German
TUV. Because these system are free of ignition sources, they
even can be used for explosive powders.
Hope that helps.
Best Regards

Re: Activated Carbon Pneumatic Conveying
Dear Sir,
You can very well use Dense Phase conveying system.Very Low pressure and small quantityof atmospheric air would be required. You can select very low velocity in this method.
You can contact us directly, in case you need the complete ystem from us.
Best regards

Re: Activated Carbon Pneumatic Conveying
I would suggest a Cable-Vey conveyor since your system is very small. The tubular drag conveyor can be grounded and these are commonly used in the coffee industry. The cost will be lower. Drive motor is only power required. No air required. Check out their website www.cablevey.com

Re: Activated Carbon Pneumatic Conveying
Amir,
Much of the sucess of trasfering carbon black effectivley has to do with the type of material you are dealing with. Carbon black is as varied a material type as you will find. From light density powder form to pellitized and coated balls. Typically vacuum conveying (standard or dense phase) will work just fine coming from the bulk bag unloader. The only option we have found that keeps the fragile coated pellet material from breaking up is interlocking bucket elevators like Unitrak or Meyer. Pnuematic transfer of carbon black is not inherently an explosion risk. If you have other plant requirements for explosion proof equipment these systems can conform to such.
We are the leading US manufacturer of bulk bag (super sack) handling equipment. We integrate that equipment with conveyors, blenders, feeders, and packaging equipment and deliver them worldwide. We would be glad to provide you with a proposal for a system like this with just a bit more information (material type, rates, distance to convey, etc.)

Re: Activated Carbon Pneumatic Conveying
Dear Mr. Amir Manoff,
normaly it is no problem to convey activated carbon with vacuum conveyors. Therefore, it is not necessary to have a filter at your silo.
The type of conveyor you need depends on the particle size of the carbon. If you can give us more details about the material and the application, than we can recommend you a conveying system. I don´t see any problems with explosion or fire risc.

Re: Activated Carbon Pneumatic Conveying
thank for all the advice we got to amir's question.
we still learn the option.
let me add the typical proprties of active carbon we are going to use:
1. apparent density 300 kg/m3
2. particle size >75 mic. 19 v/v%
3. particle size >10 mic. 91 v/v%
4. particle size D50 41 mic
feeding capacity 20-240 kg/hr
ver. distance 5 m
hor. distance 17 m
any changes to the above replies?
Thanks for your assistance ■
Activated carbon pneumatic conveying
Hello colleagues.,
We are planning to offload activated carbon big bags (600 kg each) to a pneumatic conveying system.
The activated carbon will be pneumatic conveyed into a receiving silo ( 2m3 ) at a distance of 15 meters approx.
The carbon will be dosed from this silo via a rotary valve to the mixing vessel ( where the activated carbon is mixed with the process fluid).
In this silo the pneumatic conveying air will be discharged via a bag filter to the atmosphere.
Do you see any hazard in using atmospheric air as the conveying medium?
If there is a fire hazard / explosion hazard other hazard what do you recommend to do?Which measures should be considered/ implemented?
Thanks for your assistance.
