Working Principle of Shale Shaker (I)

One of the most important solids control equipment- Linear motion shale shaker

Shale shaker is the most important cleaning equipment in the solids control system. As the first stage of drilling fluid cleaning, the function of shale shaker is to remove the solids size bigger than 70 micron meters which return from wellhead and keep the solids do not break. So that the next stage of cleaning equipment can further purity the drilling fluid. The shale shaker's working performance directly affecting the quality of first stage cleaning of drilling fluid, and also influenced the next purify stage.

Working principle and function:  The shale shaker is mainly composed of a screen frame, a screen mesh exciter and anti-vibration elements. By the vibration force  and through screen mesh hole to separate bigger solids out and by the adsorption force to separate solids size smaller than screen mesh hole. The drilling fluid coming back from wellhead to screen by feeding channel. The solids was discharged from the tail of the screen, and liquid with smaller size solids is poured into the drilling fluid system. Then finish the separation.

Now, the using shale shakers in the drilling site are all have the same working principles. That is, the eccentric shaft is driven by the motor to rotate at high speed, when eccentric shaft rotates, there is a strong centrifugal force which acts on the elastic vibrator. Thus make the shaker screens vibrate at a higher frequency.

Details will be continue on next blog.
