A method for compacting and/or filling of pulverulent materials into rigid or flexible containers in the course of which the pulverulent material is filled into the container with the help of a pipe in relative motion to the container, and separated from the gas, for example air, transported along with the help of a separation device which surrounds the pipe and is fitted to the container cross section. The pulverulent material is retained in the container with the help of the separation device, while the gas escapes through the gas permeable separation device.

Process for compacting and/or filling up pulverulent material

A powdery substance, such as for example pyrogenically prepared silicon dioxide, is subjected to predensification through the utilization of centrifugal force in a centrifuge. Subsequently, the centrifuge receptacles are closed with a free flying piston. Through utilization of the centrifugal force, there is achieved through the use of the free flying piston an additional pressure which is exerted on the predetermined powdery substance.
