Regarding the above mentioned topic, I got some questions and I would appreciate your help.

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?
