Further, when processing the high viscosity fluid, and shale shaker screen http://www.kosungroup.com/products/product-accessories/screen.html (wire mesh) easily sticky drilling fluid, the mesh size becomes smaller, or completely paste, a phenomenon known sieve paste. Since the mesh size decreases, can be isolated more small particles. Sieve Paste and sieve mesh blocking phenomenon since the effective flow area decreases, the shale shaker amount of processing will decrease, easily lead to the loss of drilling fluid.
Beyond that, cuttings and clay paste causing sieve paste and sieve block, the drilling fluid remaining in the sieve dried up, the drilling fluid soluble minerals (such as salt, anhydrite, some carbonate) will precipitate and sticky on the wire, also make smaller mesh, or even blocked. In addition, the drilling fluid oils (eg: threaded oil) in the sieve will be sticky.
Especially in the shaker is stopped working before, the sieve paste and sieve blocking, while the vibration, while water (or jet), not only help clean the screen surface, to maintain smooth mesh, while also removing the drilling fluid paste, but also reduce the screen load.
