Shale shaker is the 1 st stage separation equipment for oilfield solids control system . It adopts vibrating motor to generate vibrating force . The vibrating force drives the drilling fluid with cuttings pass through the shale shaker . When the drilling fluid goes through the shale shaker screen , clean mud will be filter ed and goes into mud tank. No n- allowable bigger solids will pass the screen surface and be discharged to cuttings pot . There are mainly two types of shale shaker applied in solids control system for drilling cuttings separation. A. Balanced elliptical motion shale shaker . It is not recommended for oil and gas drilling since the flow capacity is big. If the mud flow is not equal, the motion of shaker will be changed. And performance will not be good. Mostly, professional users prefer linear motion for wide application. B. Linear motion shale shaker . This is the most common shaker type for oil and gas drilling solids control
