Hi-g drying shaker
Hi-g drying shaker is form the first stage barrier through which the drilling fluid or the mud passes. It is basically shale meaning clay, mud or silt, that has some specific structure which has been untouched since its deposition in ground; which is here separated.
The waste is processed first in the Hi-g drying shaker before transferring it to the other equipment. It is used to separate solids with diameter above 75µm.
Different components of shale shaker are hopper, feeder, screen basket, vibrator and basket angling mechanism and vibrator. They are believed to be most vital in solid control system as their performance direct has impact on the successive equipment and also relates to the quality of processed fluids.
Desander is a devices along with desilter form pair of hydrocyclones that differentiate sand and silt from the drilling fluid in borehole or downhole. Desander is added below the mud taker following by shale shaker and degasser. A desander is typically positioned next-to-last in the arrangement of solids control equipment, with a desander centrifuge as the subsequent processing unit.
A drilling mud is added in its direction with an angle which is roughly at 90 degrees to it. As the drilling mud is moved downwards in this cone shaped equipment solid particles are segregated from liquids ones by centrifugal force acting on these.
This separated solid particles are allowed to continue move downward until is discarded from the hydrocyclones. Desander are set to eliminate abrasive solids found in the drilling mud, which surpass the processing of shale shakers . Desanders usually separate soild with diameter 45~74μm, and 15~44μm.
Different size of desanders and desilter are available which function similarly. They determine the size of particles the device removes from the mud system. Alike shale shaker desanders have no moving parts.
