Solids control shale shaker for sale in North America and Australia

Shale shaker is a vital component of drilling fluid processing system in many industries, such as coal cleaning, mining, oil and gas drilling. They are considered to be the first phase of a solids control system on a drilling rig, they are used to remove large solids also called cuttings from the drilling fluid, more commonly called "Mud" due to its similar appearance.

After returning to the surface of the well, the used drilling fluid flows directly to the shale shakers where it begins to be processed. Once processed by the shale shakers the drilling fluid is deposited into the mud tanks where other solid control equipment begin to remove the finer solids from it. The solids removed by the shale shaker are discharged out of the discharge port into a separate holding tank where they await further treatment or disposal.

The shaker screen is equipped on the basket of shale shaker, with three or four pieces screen panels, while the screen basket is driven by two sets of vibration motors which are mounted on the top of shale shaker with synchronization and contrary rotation. There exists one piece of eccentric block in the vibration motor. When motor works, the eccentric block also rotate. As there are two sets of vibration motors working synchronized, at some point, the vibration force that generated by the eccentric blocks is sum of these two blocks effect force. While at some point, the vibration force of motors would be zero.


When the viscosity of the drilling fluids increase, shale shaker process capacity would be reduced; while when the density of the drilling fluids increase, shale shaker capacity would also enhance. That is because when the drilling fluids flow onto the screen, the enhanced density would place some pressure on the screen, pushing the drilling fluids permeating the screen more quickly.
