| Popis: | The invention relates to a method and equipment for taking a sample from a suspension containing solids and liquid. One or several samples are fractionated from the feed suspension in a fractionating chamber (1; 1.1 - 1.5) by means of one or several fractionating elements (2.1 - 2.5) so that the formation of a cake onto the surface of the fractionating element or the blocking of the fractionating element is prevented during fractionation by using ultrasonic technology and/or by rotating the fractionating element. The invention can be used, for example, for taking samples from process waters. |
