Shale shaker purpose

The shale shakers are mainly powered by the rotation motors to rotate and produce the periodic changed passivity force, drilling fluid that contain solid phase pass through the mesh screen, do the forcing movement on the mesh surface, and then the solid phase debris with various size will be filtered. The separation sizes and through put of the shale shakers is the most important factors of making use decision. The technology level of shale shakers mainly show at the treating capacity, the stability of filter debris, the life of operation and the flexibility of operation. The managing ability of shale shakers is related with the structure of shale shaker steel body, the movement arrangement, the vibration frequency, the vibration intensity, the working area of shale shakers and the degree of thickness. In order to make the shale shakers match with the drilling machineries, the maximum outputs of the drilling pumps and the quantity of drilling cuttings filtered must be considered.

Shale shaker is one of the main products of GN solids control .GN  sell a series of solids control equipment and drilling waste management equipment including vertical cuttings dryer , shale shaker , screw conveyor , shear pump , oilfield shale shaker , mud cleaner , desander and desilter , vacuum degasser , poor boy degasser , decanter centrifuge , mud tank , mud agitator , etc .

The classification of shale shaker

It depends on the movement arrangement; the shale shakers can be grouped into round screen shaker, the common elliptic screen shaker, linear screen shaker, equilibrium elliptic screen shaker. The common elliptic screen shaker: also can be called the disequilibrium elliptic screen shaker, there is a exciter devices fixed right above of the screen box , the screen boxes may tilt an angle, use the leverage of the gravity, avoids the sand having the tendency of back flowing. From this, the tilt of the screen boxes really improved the flowing performance of sand, but the disposed amount of the drilling fluid reduced, this is the main disadvantage of the common elliptic screen shaker. The linear shale shakers: Two main axises with eccentric blocks do synchronous reverse rotation to produce the liner vibration. Because the direction of the liner shale shaker is unchanged, which makes the debris difficult to fall through, and then the screen paste aspect appears, which makes the valid over flowing area of screen and throughput reduced. When the number of screens increases, the aspect of screen paste will be more serious. So when the linear shale shakers use the super fines screen, it could not meet the requirements of the using amount of drilling fluid.
