Fine particles misclassification in the underflow (UF) of grinding-classification hydrocyclones might result in ore over-grinding, leading to both reduced ball mill throughput and metal recovery. In the current research, a W-shaped hydrocyclone is proposed, to efficiently decrease the misclassification of fine particles in UF. The effects of the …

One of the main application of hydrocyclone de-sanding is produced water treatment in the oil&gas upstream sector. In this case, desanding hydrocyclones are installed at the outlet of three-phase separators with the aim to protect the downstream equipments such as deoling hydrocyclone, CPI, fl otator and media fi lters.

Gas pollution in marine lubricating oil systems is harmful to the normal operation of a ship, and is one of the main reasons for the decline of the performance of lubricating oil. In this research, a classic 75 mm hydrocyclone was selected as the oil–gas separation device. A hydrocyclone is a device that uses the density difference of the …

The hydrocyclone is a simple piece of equipment that uses fluid pressure to generate centrifugal force and a flow pattern which can separate particles or droplets from a liquid medium. These particles or droplets must have a sufficiently different density relative to the medium in order to achieve separation. The flow pattern in a hydrocyclone ...

Les vertus du gypse. Un minerai composé de calcium, soufre, magnésium et fer, le gypse a de très grandes vertus. Sans effet sur le pH, il permet d'activer les bactéries dans le sol, d'améliorer l'assimilation des éléments nutritifs des plants et donc d'accroître leur résistance et de favoriser le développement des racines.
