The Structure of Shale Shaker

Shale Shaker would be the equipments that are utilized in many industries, including coal cleaning, mining, oil & gas drilling, etc. In petroleum drilling, desander system are considered to be the very first phase of solids handle system. in the drilling rig. They are used to remove the big solids and then drill cuttings from the drilling fluids which can be used to help boring holes into the earth. The clean drilling fluids with smaller particles flow through the shaker screen down into the mud tank, on which the shale shakers and other solid handle equipments are all drilling mud agitator, the solids that has been separated by the screen would be discharged out concerning the tank through discharge port. So shale shakers are considered to be the most important device in the solid control system for oil & gas drilling.

Shale shakers consist related with a welded base, screen basket, screen, locking device, shock spring, vibration motor, mud feeder not to mention explosion-proof switch, etc. They are also designed together with equipped with an angle adjustment system on the screen basket. Sometime in order to treat a comparatively large volume connected with drilling fluids, double or triple shear pump are used, where two or three shakers are combined to work together. Drilling fluids first flow into the mud feeder, not to mention then flow onto the screen. While the angle regarding the screen basket can be adjusted -1°~5° through the angle adjustment device while drilling, according to the difference related with the mud viscosity, there’s no need to stop the drilling process. Together with the vibration motor, through driving its two PCS eccentric blocks rotating, which generates the vibration force on the screen basket. In line with the difference for the solids vibration tracks, shale shakers are also divided into elliptical shaker, linear-motion shaker, not to mention circular shaker.
