Abstract: A hydrocyclone for separation solid particles from a liquid is disclosed. The hydrocyclone includes a ceramic cyclone head, a ceramic cyclone main body, and a metal enclosure. The metal enclosure includes at least an upper metallic enclosure part and a main metallic enclosure part. A lower section of the upper metallic enclosure part includes mateable circumferential threads and an upper section of the main metallic enclosure part includes mateable circumferential threads. The mateable circumferential threads of the upper metallic enclosure part and the mateable circumferential threads of the main metallic enclosure part are mateable with each other.

Abstract: Hydrocyclone comprising a ceramic cyclone head with at least one feed inlet, a upper outlet, and a head chamber a ceramic cyclone main body with a lower outlet and a main chamber, wherein ceramic cyclone main body is connected to the ceramic cyclone head so that the head chamber is in fluid communication with the main chamber; a metal enclosure with a corresponding feed inlet opening and corresponding outlet openings; wherein the metal enclosure comprises at least an upper metallic enclosure part adapted to enclose at least part of the ceramic cyclone head and a main metallic enclosure part adapted to enclose at least a part of the ceramic cyclone main body, wherein the upper metallic enclosure part comprises circumferential threads in a lower section thereof and the main metallic enclosure part comprises circumferential threads in an upper section thereof, wherein said circumferential threads are mateable.
