Re: Precipitated Silica Pneumatic Conveying
Dear Chetan,
Of course, Precipitated Silica can be conveyed pneumatically, as it is a very fine powder.
The problem is more:
-the container needs to be prepared and lined for silica tightness
-the silica content of a 20’ container will be between 3.5 to 13.5 tons, when 100% filled.
-Separating and de-dusting the conveying air from the silica in the container.
Another approach is to build a tilting- and filling station for the containers, which will be a considerable investment.
Your best option seems a bulk bag loading station and load the standard container with bulk bags by using a forklift truck.

A tank container, filled under a loading station is also an option.
The annual throughput is a very important parameter, on which a decision can be based.

Dear Sir,
Many thanks for your valuable reply.
at the moment the container is loaded with big bags only and We thought of doing the same i.e. install a container tilting unit under the silo and with a telescopic chute we can fill the container directly from the silo.
But, here we have a constraint & no possibility of installing container tilting unit. hence we though of pneumatic conveying system.
presently, in a day we have to fill the 3 x 20' container and designed to fill the 6 x 20' container for future in case required.
What should we do?? please suggest.
Regards,

Re: Precipitated Silica Pneumatic Conveying
Dear Chetan,
Obviously, you have the means for filling big bags, loading the 3 20’ containers and the company, which is receiving the containers has the equipment to unload and empty the big bags.
Each container stores approx. 30 big bags, which could take 2.5 hrs to fill.
3 containers are filled in one shift.
Expanding your production to 6 containers, can be achieved by an extra shift.
Investing in a tilting unit with additional loading equipment (f.i. screws), container internal lining (comparable to a giant big bag) and all the extra handlings is probably economically not feasible.
Opting for a pneumatic conveying system to fill the container is even less feasible, because of the extra required equipment, (compressor, tank, controls, container connections and a filter receiver, which is required to take care of the dust).
The handling of the loading operation is even more extensive as with mechanical loading.
I suggest, that you put the virtual operations for the various options on paper with all operational, financial and environmental consequences and make your choice.
This should also include the required modifications at the receiving end.
I assume that you want to use ordinary containers and not specialized containers, although a bulk tank container is a dust free and easy alternative, but probably more costly.
Best regards

De-Aeration Of Fine Powders.
Product from a pneumatic conveying system is invariably dilated and fine powders in this state can take a long time to settle to a stable condition. Big bags will be floppy and can be awkward to handle until the powder settles. It is no easy task to accelerate de-aeration, but improvements can be made by careful attention to the filling process and techniquies for providing preferential routes for the escape of air from deep beds. These range from de-aeration frames to insert and venting systems in containers. Notes on de-aeration are available from lyn@ajax.co.uk ■

Precipitated Silica Pneumatic Conveying for Filling 20" / 40" ISO containers
Dear All,
You all must be aware about the Precipitated Silica is a very fine powder with low bulk density and Hygroscopic in nature.
It has a high air retention property which leads a dusty environment and the powder will become a Milky air while conveying through pneumatic conveying system.
I would like to know whether we can use pneumatic conveying system for container filling for precipitated silica?
If yes, then whether we should use dilute phase or dense phase conveying method for proper and maximum filling of the container.
Bulk density of precipitated silica is 0.1 kg/m3 to max of 0.4 kg/m3
Please let us know your views and also, need a suggestion for how to do the deaeration of the container to settle down the powder as early as possible.
Thanks & Regards,
Chetan ■
