Below, We'll center on several frequent structural forms to help you comprehend their strengths and weaknesses, so you're able to select the ideal screen for the distinct drilling natural environment.
The display opening measurement establishes the particle size a shaker can get rid of. Display mesh is the quantity of openings for every linear inch as calculated from the middle of your wire.
Composite shale shaker screens combine the advantages of both metallic and non-metallic elements. Generally made from two to 4 layers of stainless steel wire fabric fused to some composite body, They may be bonded into a single device, then combined with metallic reinforcement plates by way of spot welding or other adhesives to sort a large-toughness construction with a sizable screening place.
The D subscript refers back to the percent eliminated to ensure inside of a D16 cut, 16% on the mentioned micron size particles are eliminated and D84 would be the micron dimensions where by 84% from the solids are eliminated. These D measurements are decided from the particle size distribution from the feed liquid and solids discharge. The mixture in the display screen D50 plus the ratio with the D84 divided by the D16, gives a more total image with regards to separation effectiveness. shaker screens The D84 / D16 ratio suggests how specific or “sharp�?the Slash issue is �?where all the solids down to a certain dimension are eliminated but Not one of the scaled-down particles are taken off.
The patented DURAFLO composite screens had been created by United Wire and M-I SWACO as an alternative to metallic-framed shale shaker screens staying made available being an market normal.
Our proprietary display screen technologies will let you increase solids Manage effectiveness, minimize the volume of essential screens, and decrease In general display prices.

In the new API 13 C procedure, a take a look at have to be carried out exactly where the actual permeability of your shale shaker display screen is set utilizing regular oil and a laminar move sample. The two the permeability and also the open up place have to be printed within the screen label. An illustration of a display label is offered below.
In the end, the knowledge supplied didn't signify exactly what the customer was on the lookout for. Under the API 13C scheme, a maker is obliged to check the screens applying aluminum oxide particles that resemble the general shape of cuttings. The particle measurement that is definitely quoted for the screen has to be the utmost sizing of any particle that might go the display. A list of API indicators was created that remains to be related to the approximate throughput measurements of your Earlier used Mesh technique. Both of those the API indicator and the maximum dimensions of a particle passing the display needs to be pointed out to the screen label.
