WELL SCREENS Introduction
the screen should not exceed 1/10 or .1 foot per second. The velocity is calculated by dividing the well yield in gpm by the screen open area in square inches. The slot size of the screen is based on a size analysis of the formation samples. By analyzing the component sizes of the grains in the sample, a grainsize distribution curve can be drawn.

How to Build a Home Sand and Gravel Screen Hunker
Screen your own sand and gravel using a selfmade screen. You don''t need to pay for commercially screened materials when they are sitting in your own backyard. The only difference between these natural materials is their size so sifting separates the gravel from sand and further sifting separates fine sand from coarse sand.
Maximizing Screening Efficiency
The area available on a screen for a aggregate particle to fall through a hole in a screen. Usually expressed as a percentage. • Screen Efficiency The percentage of material that falls through a screen compared to the total amount of material in the product stream of that size. • GForce of a Screen

According to size coarse aggregate is described as graded aggregate of its nominal size i.e. 40 mm, 20 mm, 16 mm and 12.5 mm etc. for example a graded aggregate of nominal size 20 mm means an aggregate most of which passes 20 mm IS sieve.
Mesh (scale) Wikipedia
Mesh is a measurement of particle size often used in determining the particlesize distribution of a granular material.For example, a sample from a truckload of peanuts may be placed atop a mesh with 5 mm openings. When the mesh is shaken, small broken pieces and dust pass through the mesh while whole peanuts are retained on the mesh.

Dewatering Screens McLanahan
The smallest aperture on a Dewatering Screen is typically 0.3mm (50 mesh), so you will expect to see some of that size fraction and finer in the underflow of the screen. Not all of that fraction will pass through due to the very nature of caking style screens fines are captured in the bed formed on top of the media.
