PCT No. PCT/SE78/00029 Sec. 371 Date May 9, 1979 Sec. 102(e) Date May 9, 1979 PCT Filed Aug. 10, 1978 PCT Pub. No. WO79/00137 PCT Pub. Date Mar. 22, 1979 This specification describes a method of separating a fine-grained close-packed solid material from a liquid with which the fine-grained material is saturated. The material may by way of example consist of grindings; metal-containing pickling bath deposits; or metal oxides from metallurgical venturi-filter. The moist mixture (1) is packed in a container (2) which thereafter is closed and heated from underneath. The liquid is evaporated starting from the lower portions in the container and forces liquid from the upper portions towards the surface of the paste-like mixture, wherefrom collected liquid (9) can be removed. Common oil drums can be used as containers. When the liquid has been removed the containers with enclosures can be charged in metallurgical furnaces or can the material be dumped together with waste material without any effects detrimental to the environment.

Method of separating a solid and a liquid phase of a mass

The invention relates to an apparatus for atomizing a molten material, by disintegration of a stream of the molten material by fluid jets directed under high pressure against said stream, a first and a second fluid jet generated at opposite sides of the stream being converged towards a point of intersection lying aside of the stream of molten material, said first fluid jet being spread out in a plane intersecting the stream of molten material at an acute angle, said second fluid jet extending within .+-.10.degree. relative to the original direction of the stream of molten metal. The invention is characterized in that said second fluid jet is imparted the shape of a curved curtain with its concave side facing the stream of molten material, and the second nozzle, in a plane perpendicular to the pouring direction, is curved with its concave side facing the casting opening and directed essentially in the same direction as said casting opening.
