Shale Shaker Screen

The Drilling Fluid Shale Shaker is the first-level purification equipment of the Mud Recycling System for Drilling Rig. The Drilling Fluid Shale Shaker separate the large and useless solid particles in the drilling fluid, and is one of the most important equipment in the Mud Recycling System for Drilling Rig. The Drilling Fluid Shale Shaker mainly separates the useless solid phase in the drilling fluid to the maximum extent, recovers the useful liquid, and reduces the filtration loss, thereby reducing the requirements for new drilling mud, thereby reducing the input cost of new mud materials, thereby reducing the total drilling cost. At the same time, more drilling fluid is recycled, the solid phase in the drilling fluid is reduced, and the cost of drilling waste disposal is also reduced.
The Shale Shaker Screen is an important accessory of the Drilling Fluid Shale Shaker and the wearing part with the largest consumption. Therefore, the quality of the Shale Shaker Screen can determine the cost of drilling to a certain extent. Therefore, a Shale Shaker Screen with a long service life is very important for the drilling fluid vibrating screen. Therefore, many companies have spent a lot of energy on the structural design of the screen and the hole design of the wire mesh, so that the screen not only has a long service life but also has a high separation efficiency. For example, Derrick invented the Pyramidal Shale Shaker Screen(PMD), and MI-SWACO invented the Composite Frame Shale Shaker Screen. These inventions and creations are all for one goal: to maximize the separation of the useless solid phase in the drilling fluid, to recover the useful liquid, to reduce the filtration loss, to improve the screen and work efficiency, to increase the service life of the screen, and to minimize the drilling cost.

ASTM is short for The American Society for Testing and Materials, ASTM E11:01 mesh equals to ISO 33101:2000 mesh. This method determines the cut point of single layer ASTM screen mesh size. For shaker screen mesh, normally means the surface screen mesh size. Whilst the shaker screen is usually a composition of 2 or 3 layers, the cut point of the first layer mesh is not equal to the final shaker screen cut point.
API is short for American Petroleum Institute, “API Number” is determined by API RP13C or ISO13501, the cut point is related to the combined 3-layer wire mesh test result. So before order, we will need API number, or the cut point, to define a more proper shaker screen configuration.
