Apr 04, 2019 Hydrocyclone. The hydrocyclone is a device for separating and removing substances such as heavier coarse-grained silt from sewage, and sometimes used for mud dewatering. It is divided into two types: pressure type hydro cyclone separator and gravity type. It is usually made of a circular column structure or metal tube

For desliming purposes, normal classification takes place in the upper portion of a cyclone; this can be thought of as the first stage of desliming. The CycloWash, located in the lower/apex section of the hydrocyclone, injects water into the cyclone, and the injection water displaces the fines-laden water in the partially thickened underflow pulp

Oct 13, 2017 Desliming Cyclones. Analysis of the feed to several plants revealed that the material finer than 44 m (325 mesh) and even 70 m (200 mesh) was usually very high in ash content ( 30 %) with a considerable amount of superfine size clays. Due to the high ash content and the poor dewatering ability of the minus 44 m coal when recovered, it
