Linear Motion shale shaker

what exactly is a linear motion shale shaker? How does it work in a rig? The equipment uses linear or rectilinear motion through its vibration mechanism to effectively remove solid particles from drilling fluids. Fluids containing solids are conveyed onto the screens of ashale shaker, where the vibrations cause the particles to separate from the liquid, allowing clean fluid to pass through for further use. The separated cuttings are then collected and processed to prevent them from interfering with the drilling process.
