Shaker Screen

What Is Shaker Screen

Shaker screens are constructed with a hooked edge profile on wire cloth or wire mesh panel. They provide an essential function in the sizing, sifting, and grading process in various industries such as minerals, sand, and agriculture. Shaker screens work by vibrating the material to be screened. The vibration causes the material to move across the surface of the screen, separating one medium from another. This includes sizing larger items from smaller ones or solids control. The larger items are collected on the surface of the screen, while the smaller items pass through and are collected in a separate container. A shaker screen is typically made up of several layers of mesh or wire cloth arranged in a series of decks, with each deck having a progressively finer mesh size.

Advantages of Shaker Screen

Improved processing and material quality
While certain screening equipment is better suited for different materials, vibratory screens offer a number of advantages in aggregate and mining materials processing. Shaker screens are particularly well-equipped to meet the fineness requirements of these industries. Their design, which is able to generate the force required to separate oversized particles from fines, results in easier recovery of product – even when handling a material that requires significantly smaller size separation. This leads to both higher yields and an overall improved quality of the final product.

Lower operational costs
Shaker screens are known for their robust design. Because the operating principle is relatively simple, and the design of modern machines is streamlined, the screens can generally be purchased for less than other types of screeners. This results in a lower upfront investment.

Less maintenance and downtime
Maintenance and downtime as a result of repairs or equipment failures can lead to a major loss in both productivity and profit. Many types of screens undergo significant wear and tear, particularly in demanding applications like aggregate processing. However, vibratory screeners offer the advantage of less maintenance and downtime. This is a result of their design, which centers around delivering vibratory forces only to the screening surface.

Higher screening efficiency
While there is a wide range of screening equipment available on the market, shaker screen machines offer an ideal choice when an operation requires a simple solution that can handle a higher feed flow. In fact, they work most efficiently with a consistently higher flow rate. For other types of screening equipment, the same material throughput could lead to screen blinding or a backflow of materials that requires a slower feed.

The Shaker Screens Performance Affected by Those Factors

01/

Material factors
Particles in dry bulk materials are noted in a variety of shapes, sizes, surfaces, densities, and moisture content. Each condition must be taken into account when attempting to predict screen performance, through its effect on capacity in terms of weight passing a given screen opening per-unit area. The combined effects on screen performance, or ‘screen-ability’, of particle shape, surface texture, and surface or internal moisture, are beyond the reach of empirical solutions based only on size and density, independent of these variables. More exact information on their influence needs to be gained from actual laboratory testing.

02/

Size and shape
The shape of an individual granule may be angular, spherical, acicular, ovaloid, flaky, or slabby. They can be combined in the same material, as sawdust in wood flakes. Separation cut-point sizes in most screening applications range downward from 4’’ to 325 mesh (.0018’’). The cut-point defines the smallest particle size retained on the screen, and the maximum undersize particle passing. Unless the particle is acicular, platy, ovaloid or a perfect sphere, it will be probably (but not necessarily) be sized by its largest dimension.

03/

Density
For any given shape and size distribution, bulk density in lb./cu. Ft. (pcf) for any material will be precisely proportional to its specific gravity. Screening is essentially a volumetric measurement, but capacity, or the rate of passage through the screen, is typically charted in units of weight per unit time, based on a standard bulk density of 100 pcf. The actual rate for a material of different bulk density has to be adjusted by the ratio pcf: 100. Tables of bulk density for various materials can be discovered in most material handling publications.

04/

Size distribution
The size distribution of particles in a bulk granular material is the primary characteristic that governs the rate of undersize passage through a screen opening that is larger than the smallest particle and smaller than the largest particle in a representative sample of the material. Size distribution is measured by sieve analysis, using a series of standardized wire mesh sieves with square openings that progress, in the commonly used tyler standard scale7, at the fixed rate of from 1.05’’ to.0029’’ (200 mesh). The size distribution is given in the weight percent of each fraction between successive sieves in a series. If the weight is plotted on the y-axis against the mean size of each fraction of the x -axis, the result will resemble a frequency distribution curve.

Factors Influencing Screen Size Selection

Application specifics
Different drilling applications demand varying screen sizes. Factors like drilling depth, mud properties, and solids content guide the selection process.

Drilling conditions
The geological makeup and drilling conditions also dictate optimal screen size selection. Abrasive formations might require finer screens for efficient solids control.

Fluid properties
The viscosity and density of drilling fluids affect the screen size choice. Fluids with high viscosity might necessitate larger openings to prevent blockages.

Material Factors Affecting Shaker Screen Performance

Size and shape
The shape of an individual granule may be angular, spherical, acicular, ovaloid, flaky, or slabby. They can be mixed in the same material, as sawdust in wood flakes. Separation cutpoint sizes in most screening applications range downward from 4’’ to 325 mesh (.0018’’). The cutpoint defines the minimum particle size retained on the screen, and the maximum undersize particle passing. Unless the particle is acicular, platy, ovaloid or a perfect sphere, it will probably (but not necessarily) be sized by its largest dimension.

Density
For any given shape and size distribution, bulk density in lb./cu. Ft. (pcf) for any material will be directly proportional to its specific gravity. Screening is essentially a volumetric measurement, but capacity, or the rate of passage through the screen, is typically charted in units of weight per unit time, based on a standard bulk density of 100 pcf. The actual rate for a material of different bulk densities then has to be adjusted by the ratio pcf:100. Tables of bulk density for various materials can be found in most material handling publications.

Moisture
Moisture in granular particles may be absorbed, adsorbed, or both. Either condition can impair screenability, but tolerance is much greater for internally absorbed than for external surface moisture. Surface moisture causes particles to stick together, resisting stratification. Allowable surface moisture for unimpaired dry screening of inorganic granular or pelletized particles ranges from bone dry for screen openings below 20 mesh to 3% for 1/4’’ openings. Absorbed moisture in permeable soils such as ground clay can block the screen openings with cumulative buildups of extreme fines attached to the screen wires. Absorbent grains such as corn, soybeans, wheat, etc. Will screen freely after drying to 13-15% internal moisture. Screening of wood chips, flakes, and sawdust is unimpaired up to about 30% internal moisture; however, in laboratory tests with sawdust, efficiency was reduced by almost 60% when moisture was increased to 68%.

Size distribution
The size distribution of particles in a granular bulk material is the primary characteristic that governs the rate of undersize passage through a screen opening that is larger than the smallest particle and smaller than the largest particle in a representative sample of the material. Size distribution is measured by sieve analysis, using a series of standardized wire mesh sieves with square openings that progress, in the commonly used tyler standard scale7, at the fixed rate of 2 root square from 1.05’’ to .0029’’ (200 mesh). The size distribution is expressed as the weight percent of each fraction between successive sieves in a series. If the weight is plotted on the y-axis against the mean size of each fraction on the x-axis, the result will resemble a frequency distribution curve.

Things to Know Before the Selection of High-Quality Shale Shaker

Mesh size
The screen opening size determines the size of the particle that can be removed in the process. In the easier term, mesh size can be explained as it is the number of openings per linear inch as calculated from the center of the wire. For instance, in 70 by 30 oblong shale mesh screen means it has 70 openings in a one-inch line one way by 30 openings along a one-inch line perpendicular to the first. However, the actual separation size depends on the factors like fluid viscosity, particular shape, particle cohesiveness, and feed rates. In the same case, the drilling fluid forms high surface tension film on the screen’ s wires and even clogs the effective opening size of the screen.

Design of the screen
Shaker screens are available in two and three-dimensional designs. Panel screen that comes with two or three layers bounded at each side by one piece, double folded hook strip.Perforated plate screens come with two or three layers that are bounded to perforate, the metal-plated available in the setup provide easy support and are quite easy to repair. On the other hand, a three-dimensional screen design comes with a perforated plate screen on the corrugated surface that runs in parallel to allow the flow of the liquid. This configuration allows more screen space in comparison to the two-dimensional screen configurations.

Screen specification
Api recommends that all screens should be labeled with their respective name and potential for separation. This information should be considered seriously to make a sound decision; a wrong step in this direction can leave a reverse impact on the output.

Flow capacity
It is one of the essential factors that help in the selection of the right shaker screen. Two parts are needed to be monitored quite closely to determine the flow capacity. It includes non-blanked and conductance areas. The conductance of the screen is the amount of fluid that passes through the screen per unit time is a quite important parameter in the selection of the minimum size of the screen that can effectively work under the drilling conditions. The old system manufacturers would share their percentage of the open area and claim the optimum screen life. These two properties will counteract as a large open area can be obtained only through thinner wires. However, in the new api shaker screen system, a test is conducted which helps in determining the actual permeability of the screen. It is determined with the help of standard oil and laminar flow patterns. The open area and permeability information must be printed on the screen label for the rightful purchase.

Shaker screen’ s plugging and blinding
Screen blinding is a common issue that occurs when the grains of the solids are lodged in the screen hole. This occurs when drilling the fine sands. In such a case, it is recommended to choose a coarser or finer screen than the regular one. This strategy will turn out successful if the sand that is being drilled has narrow size distribution. Another alternative is to change the regular screen to a rectangular screen, although the chances of screen blinding are also possible with the multiple sand grains.

What Are the Basic Shaker Screen Size Categories

Fine mesh screens
Api 100 to api 325 screens suit finer solids control needs, offering efficient separation of smaller particles.

Medium mesh screens
Api 60 to api 100 screens strike a balance between efficiency and capacity, suitable for moderate drilling conditions.
