Abstract: The invention relates to a device for separation of substance mixtures on the micro scale. The invention further relates to a process for separating substance mixtures using the inventive device.

Abstract: A self-cleaning separator is described for cohesive or adhesive solids from a fluidborne stream of solids on the basis of a cyclonelike separation. The separator consists at least of a cylindrical upper section (8) having a separating chamber (3), a product inlet (2), a fluid outlet (5), and of a conical lower section (6) having a solids outlet (7) adjoining below the lower section (6), at least the side wall (4) of the upper section (8) being produced from an elastic material, in particular an elastomeric material.

Abstract: In the process for the continuous collection of pulverulent or dusty samples from a particle-laden stream, a sample stream is drawn off from a particle-laden main stream in a pneumatic conveying line 17 and passed via a collection line 9 to a particle size measurement device 10. In order to reduce spin, the main stream in the conveying line 17 is passed through a venturi-like cross-sectional constriction 3, 4, 5, the cross-sectional area of which is 10 to 60% of the free cross-sectional area of the conveying line 17. Samples are then collected downstream from the cross-sectional constriction through one or more probe tubes 7, wherein a partial stream is collected from the main stream parallel to the direction of flow thereof.
