Hook strip flat screens are multilayer screens intended specifically for shale shakers. They commonly include two or 3 levels of 304 or 316 stainless steel wire cloth affixed to a steel backing plate. A great upper mesh layer gives precise filtration, whilst coarser middle and decreased layers provide assistance to take care of stable functionality beneath higher masses.
Shale shakers absolutely are a standard phrase for your vibrating product used to screen solids from a circulating drilling fluid.
Hook Strip Flat Shale Shaker Screen Renowned for their top-quality dress in resistance and significant throughput, these screens can proficiently individual solids even though processing massive volumes of drilling fluid, and they're simple to eliminate and keep.
Other configurations have already been attempted but haven't become commercial. Nearly all of shale shakers movement the drilling fluid in excess of a rectangular screening area. Larger solids are taken off with the discharge finish, While using the scaled-down solids and drilling fluid passing throughout the monitor(s) into the active method.
On the forefront on the separation process lies the shaker screen, whose design is as vital as the mechanical vibrations that drive the shale shaker. Display screen panels are engineered to:
Solids loading premiums don't negatively impact the efficiency from the downstream shakers shale shaker and lead to solids Establish-up while in the active method.
The display’s openings are calculated making use of PC-dependent picture Investigation technology. Each and every opening from the screen is then represented by a spherical diameter similar to an ellipsoidal quantity calculated with the picture Examination info. The cumulative quantity of those ellipsoids, when plotted for a function of spherical diameter, yields a curve that correlates nicely Together with the normal grade effectiveness curve.
Drilling fluids are integral into the drilling method and, amongst other functions, provide to lubricate and cool the drill bit together with Express the drilled cuttings from the bore gap. These fluids are a mix of varied chemical substances within a h2o or oil primarily based Answer and can be extremely costly to generate.
The solids limit is the most level of solids that screens can separate off the conclude on the shaker.
The tapered valleys, when relocating beneath substantial G's, implement a compression force on the solids comparable to wringing out a cloth to draw out liquid.
Display Lifetime of good mesh screens may differ commonly from design and style to style and design, even under the Better of situations, as a consequence of distinctions in functioning qualities. Monitor daily life may be maximized by pursuing these general precautions:
Screen blinding takes place when grains of solids remaining screened lodge inside of a display screen hole. This generally happens when drilling fantastic sands, like while in the Gulf of Mexico. The subsequent sequence is usually observed all through display blinding.
Appropriate range and software of acceptable shale shaker screens can enrich the efficiency of solids separation, increase gear provider lifetime, and appreciably reduce the two drilling and servicing prices.
