Kindly explain how you expect to deliver the material to the filter baghouse.

Make your mind up whether pneumatic conveying does or does not work for this hypothetical material.

Blockages happen all the time even when the material has been sampled before committing to a design.

You need to be more specific with your situation. ■

I am almost in the picture now.

If you talk to Ms Mohandes it might help. She can be found through the forums.

She has very recently asked about stack height from the filter baghouse and also, in another thread asked for a wet scrubber supplier.

I think you might have similar problems. A scrubber should not block and you could dewater with a suitable belt, drum or disc filter.

Sometimes it is better to make a clean sweep, so to speak. Downtime costs money. ■

Screw conveyors incorporating 'Lynflow' ribbon flights are used for handling cohesive and 'sticky' material, such as pastes and awkward materials, as their construction helps to keep material away from the centre shaft and avoids corners and adverse helical flight faces. ■

The only solution I know of would be to use a belt conveyor with a teflon or teflon coated (or a similar slippery material) belt. There would have to be a scraper across the belt located at the underside of the belt just inboard of the end so that anything that was still stuck to the belt as it moved around the end roller and started to go back under to return to the inlet would be knocked off. Check out this case study as well:

If I would have a powder that has such a high cohesiveness and stickiness, so it wouldn’t even pass through a rotary valve or a screw conveyor of a bag filter, how will the possible measures look like in order to extract it from a filter? How can the transport over let’s say a length where a pneumatic transport is usually used? Pneumatic transport won’t work because of the stickiness. This material will simply stick and therefore block the pipe after time. Is there any known industry, which produces a powder with comparable powder characteristics with very bad handling properties?

Thanks!

For (very) sticky cohesive materials you may consider this kind of bin discharger

or chain conveyor designed to discharge

But first it is necessary to make some bulk analysis to get the properties considering also that these may change if the product remains some time in a bin (30 minutes, 1 day, 2 days).

Please tell us how you managed your case, and add some pictures.

You are digging up old threads and hoping they will still be around. Maybe you should concentrate on the latest threads while promoting your products. Please check the thread dates before you post.

Better yet it might even be worth your while to advertise on this site.

Thank you, Garry.

But people also read this sites as an knowledge bank, because you can read many good answers and questions. By myself I learn here what the old experienced answers.

thanks again, and see you arround
