Shale shakers (Linear motion) – generally use two motors for vibrating in-phase separation. The structure of this shaker is typically plain and easy to maintain. . When the cumulative volume of these ellipsoids is plotted as a function of spherical diameter, then it yields a curve that correlates with the standard grade efficiency curve .Shale shakers are components of drilling equipment used in many industries, such as coal cleaning, mining, oil and gas drilling.They are the first phase of a solids control system on a drilling rig, and are used to remove large solids (cuttings) from the drilling fluid ("mud"). Drilling fluids are integral to the drilling process and, . See more
