Abstract
A device for transferring solid particles from an area of higher pressure to one of lower pressure. A stack-up section (3) between the areas is full of particles and large enough to reduce the current of gas flowing through the open stack-up section from the area of higher pressure as a result of the pressure loss that occurs in the stack-up section to a level that prevents pneumatic conveyance of the particles. A conveyor is in or at the end of the stack-up section.
