device for dosed enter a dust in a traegergasstrom.

摘要

An apparatus for the dosed incorporated of a dustlike substance into a carrier gas stream is described; said apparatus operates on the basis of a perforated disc which rotates in the dust, the passage holes of said disc are filled with the dust and are blown out in a blowing zone. Since a predetermined blowing pressure is maintained and owing to a suitable dimensioning and arrangement of the passage holes, a remarkable increase in the throughput of dust is achieved, compared with the prior known matter.
