Abstract: HOE 77/F 207 PROCESS FOR IMPROVING THE PROCESSING PROPERTIES OF POWDERY POLYOLEFINS of the disclosure: The invention relates to a process for improving the processing properties of powdery polyolefins. It is endeavored by this process to obtain a polyolefin powder which can be processed on screw extruders to an almost bubble-free product. The polyolefin powder is heated to a temperature of between 40.degree. C and its melting point and introduced into a gap between two gap forming elements. In this gap, the powder is compressed with a pressure of from 0.1 to 10 t per cm of gap length, and the powder so compressed is then comminuted.

Abstract: By means of a method for the uniform distribution of a small amount of liquid onto the surface of finely divided solids, characterised in that the said liquid is sprayed by means of one or more ultrasonic jet(s) onto the finely divided solids to be treated before or during, or before and during mixing of the said solids in a mixing apparatus, granules, powder or dusts can be dedusted by the use of very small amounts of liquid. The method according to the invention is also suitable for applying emulsions, solutions, dispersions or melts onto the surface of solid particles. The invention also relates to an apparatus for carrying out the said method, characterised in that one or more ultrasonic jet(s) is or are combined with a mechanical or pneumatic mixer.
