How to Use Shale Shaker?

Shale shaker is a important device on the rig for removing drilled solids from the mud. This vibrating sieve is simple in concept, but it is complicated to use efficiently. Screen vibrates while the drilling fluid flows on top of it. The solids smaller than the wire mesh pass through the screen, and the larger solids are retained on the screen, and eventually fall off the back of the device, and the larger solids are discarded. Therefore, the drilling crew should seek to run the screens, the screen is fine as possible.

Where it was once common for drilling rigs to have only one or two shale shakers, modern high-efficiency rigs are often fitted with four or more shakers, give the crew the flexibility to run increasingly fine screens.
