For drilling mud shale shaker, the shale shaker screens is anther mainly device, it mainly can remove the solids that are larger than the screen mesh openings. The drilling mud with small solids would flow through the screen meshes, and down to the mud tank for the further purification. while the large solids or the cuttings would stay on the screen, and be vibrated and flow to the discharge end of the shaker basket. So It is highly necessary to choose a proper screen according to the solids diameter, mud gravity, viscosity & density etc. As improper screen selection can lead to loss of expensive drilling fluids, premature pump failures, overloading of other solids removal equipment such as a centrifuge, decreased equipment life, reduced rate of penetration and serious problems in the well bore.
Shale shaker screenscontain steel frame type, pyramid type, hook strip flat type and composite material type. Produced with different raw materials and structures, the product can support different equipment to implement screening the solids with different sizes. The steel frame product mainly consists of steel frame and 2 to 3 layers of stainless steel meshes which integrate with steel frame tightly.
It has rather high strength and fits for screening the solids with large weight. The pyramid product has comparatively large effective area and can be used more flexibly. The specially designed hook strip flat product has long lifespan and high strength for the bottom, coarse wire screen mesh with small mesh number is integrated with the steel liner tightly. In addition, KOSUN provides the shale shaker screens made of composite materials. The dimension of this kind of product can be customized according to customers' requirements.
Shale shaker screen surface: usually, larger contact area screen will have better treating capacity, the more screen surface area you have means more volume that you can clean. Therefore, the vavy screen is better than flat screen; the larger area flat screen is better than small area flat screen.
Shale shaker screen selection: mesh size of screens is measured by the number of holes per square inch on the screen. Different mesh sizes control the size of the cuttings that you want to remove. The same mesh size will not work in all drilling conditions. Sizes will vary depending on the size of the cuttings and the type of formations you are cleaning.
KOSUN shale shaker screens are engineered to meet the exact models of "Derrick" equipment company shale shakershale shakers and can be installed directly on the shale shakers. At the same time, KOSUN shale shaker screens have another feature that it adopts the wavy mesh on the frame to extend the screen area and improve the efficiency of process.
