Vibrating Screen Bed
Depth Formula
The feed to a vibrating wire mesh screen contains a mixture of material in varying sizes. The oversized material will retard passage of the undersized material, creating a temporary restriction which results in a build-up (bed) of material on the surface of the screen.
Bed depth diminishes as the undersize material passes through the wire mesh screen apertures.
The material bed should not be allowed to reach a depth that prevents the undersize from stratifying before discharge at the wire mesh screen surface end.
Generally, the discharge end bed depth should not exceed four times the size of the wire mesh screen surface aperture when separating 100 lbs. per cubic foot material, or three times for 50 lbs. per cubic foot material.
Aggregate, Ore and Gravel Screening Formula for calculating theoretical discharge end bed depth:
DBD =
______O x C______ 5 x T x
W
= Inches of Bed Depth
DBD = Discharge End Bed Depth
O = Oversize in STPH
C = Cubic Feet Per Ton of Material
5 = Formula Constant
T = Rate of Travel (nominal 75 fpm for inclined screen at slope of 18º to 20º with flow rotation and nominal 45 fpm for horizontal screen)
W = Width of Screening Area in Feet
Basic Wire Cloth and Wire Mesh Weaving Methods
The weave type is the manner in which warp (lengthwise with roll) and weft (across roll width) wires are interwoven. Each weave type has special advantages which must be considered when selecting the correct type for a specific application.
Wire Cloth is woven in two general classifications, common (loom force crimped) or precrimped, both groups include a wide variety of distinct patterns.
Common Weaves
Specifications of 10 Mesh or finer are typically woven of smooth drawn wires which are "force crimped" into place during the weaving operation by the loom ram.
As the ram (often referred to as the beater) moves forward pushing the weft wire into position between the warp wires, both warp and weft wires are deformed (crimped) in a proportional relation to the wire tensile/yield strength.
Wire cloth is most frequently produced in common weave patterns as it is more economical in course to medium mesh production and essential in the production of fine mesh specifications.
Precrimped WeavesSpecifications coarser than 10 mesh are typically woven of wire that has been crimped before the weaving process.
Precrimped weaves are produced in two separate operations, first the wires (typically both warp and weft) are crimped (deformed) to suit the selected pattern and mesh count, then the "precrimped" wires are woven together on the loom. The crimping operation may be accomplished through the use of a wheel crimper or a punch crimper. The wheel crimper is more practical in finer mesh specifications and coarser mesh specifications on substantial quantity production runs. Punch crimping is most practical when working with larger diameter wire due to its strength, or when production
Common Weaves, Wire Cloth Weaving Styles
Plain Woven
The most popular wire cloth weave. Each weft wire passes alternately over and under each warp wire and each warp wire passes alternately over and under each weft wire. Warp and weft wire diameters are generally the same.
Twill Weave
Each weft wire alternately passes over two, then under two successive warp wires and each warp wire passes alternately over two and under two successive weft wires, in a staggered arrangement. Twill weave is normally used to allow a heavier than standard wire diameter in association with a given mesh.
Plain Dutch Weave
While the warp wires remain straight, the weft wires are plain woven to lie as close as possible against each other in a linen weave forming a dense strong material with small, irregular and twisting passageways that appear triangular when diagonally viewing the weave.
Dutch Twill Weave
Similar to Plain Dutch weave, except that the weave is twilled, allowing a double layer of weft wires. There are no apertures in the true sense of the word as the filtrate follows a sinuous path through the depth of the wire cloth.
Reverse Dutch Weave
This is the reverse of the Plain Hollander (Dutch) weave, in that the weft wires are heavier than the warp wires.
Pre-crimped Weaves, Wire Cloth Weaving Styles
Wire cloth woven of previously crimped wires provides accurate openings and is woven tighter than plain weave. Pre-crimped weaves are preferred for vibrating screens and many other applications where sizing is critical. Space Screen and Square Mesh in 10 mesh and coarser are typically woven of precrimped wires.

Comparative Gauge / Decimal Wire Diameters
Gauge sizes are indicated as whole numbers, the tables below give the decimal equivalents of the different gauge numbers. Much confusion has resulted from the use of gauge numbers, in ordering wire cloth or wire mesh it is preferable to state the exact dimensions in decimal fractions of an inch or a millimeter. The decimal method of indicating wire diameters has the advantage of being self-explanatory, whereas arbitrary gauge numbers are not.
Most common wire cloth specifications such as Bolting Cloth, Filter Cloth, Fine Mesh, Market Grade and Mill Grade utilize decimal wire diameters.
Industrial Hardware Cloth and Space Cloth specifications are typically identified by a gauge number rather than the actual decimal value of the wire
diameter.

Diameter Tolerances
Weaving Wire
The wire diameter tolerance before weaving shall be in compliance with the table below. Mechanical deformation of the wire occurs during the weaving process, therefore the wire diameter if measured
after weaving, should only be interpreted as a guide to the original diameter prior to weaving.

Wire Cloth FormulasWire Mesh FormulaIf opening and wire diameter are known, add both and divide the sum into 1.
Mesh =
1
(D + O)
D = Wire Diameter
O = Opening Open Area FormulaThe percentage of wire cloth open area may be determined by the following equation
% OPEN AREA = (1-ND) (1-nd) x 100N = Wires Per Inch in Warpn = Wires Per Inch in ShuteD = Diameter of Warp Wired = Diameter of Shute Wire
Compute Wire Cloth OpeningTo determine a wire cloth opening, divide the mesh count into 1, and subtract the wire diameter.

Vibrating Screen Installation and MaintenanceYou can dramatically increase the life of your wire cloth screens and do a more efficient job of material screening by following these steps.
Screen Installation1. Channel rubber or crown bar rubber must be replaced before
new screens are installed to assure longer screen life.
2. Use new tension bolts and tension all bolts equally on both sides of the deck.
3. Screens should be centered on the deck before clamping rails are applied.
4. Make certain butted screen panels are tight together to avoid oversized material leakage.
5. Clamping rails must be the exact length of the screen panel being installed.
Never overlap clamping rails.
6. After 4 to 8 hours of operation, retighten the screen to take up any stretch that might have occurred.
Screen Maintenance1. Inspect all clamping bars for corrosion
and wear.
Make sure bars are not warped
or worn to the point that they cannot provide even, tight tension.
2. Inspect all nuts and bolts.
Replace all worn or damaged parts in the screen assembly.
All hole positions on the clamping bars must be utilized.
3. Maintain the support deck.
Remove channel rubber to inspect steel bars for wear, high and low spots, or bar breakage.
Support area must be uniform to ensure an even and tight screen fit.
4. Change your channel rubber frequently.
Remember that channel rubber will wear from the bottom up as well as from the top down. Check both sides.
Never mix channel rubber sizes or styles such as Flat-Top and Round-Top on the same deck.
5. Check cushion and spread of material feed.
Cushioning of feed to the screen deck is essential to long screen life. Use feed plates or stone boxes so that materials do not hit wire cloth directly.
Material should be spread out to feed evenly over the entire screening surface for maximum screen life and production.
This also reduces uneven wear as the vibrator is operating in a more balanced condition.
6. Inspect equipment for balance and excessive vibration.
An unbalanced machine can cause premature wire cloth failure.
Equipment with a violent, uneven vibrating motion will cause stresses in the screen, and the cloth may actually break apart.
Correct the unbalanced condition before continuing screening operation.

Woven Wire Cloth SelectionThe following information is required to process your inquiry promptly and efficiently: Mesh -or- OpeningThe mesh count (number of openings per linear inch) or the desired opening (clear space between adjacent parallel wires) should be entered in the form.
Wire DiameterThe wire diameter has a direct proportional relationship between strength and the percentage of open area. As the wire diameter increases, strength increases and open area decreases. As the wire diameter decreases, the open area increases and the strength decreases.
Greater strength improves screen life.
Greater open area improves screen throughput. If you require assistance in selecting the wire diameter, please provide detailed information regarding your application in the "Comments" text box.
MaterialThe pull down menu in the material field contains several different types of materials that are most frequently utilized in the production of wire cloth.
For assistance in material selection, provide detailed information
regarding the application in the "Comments" section.
Roll LengthThe standard woven wire roll length is 100' although shorter or longer rolls can be provided.
If you prefer, wire cloth can be provided in panels rather than in roll form. Panels may be produced by cutting existing roll stock to the desired length or cut to length during the weaving process.
Please indicate the desired roll or panel length. Any critical tolerances should be specified in the "Comments" text box.
Roll WidthStandard roll widths are 24" 36" 40" 48" and 60". Narrower specifications may be slit directly on the loom or as a secondary operation from existing roll stock.
Edge ConditionNormal raw (slit) edges will be provided unless otherwise specified.When necessary, smooth selvage edges can be provided at extra cost. The most popular selvage is "looped" although brushed, feathered, plastic coated or welded edge treatments are available by order.
QuantityPlease indicate the number of panels (pieces) or rolls required.
If the total quantity is to be delivered in a number of shipments, please specify the amount desired per release and the dates required in the "Comments" text box.
WIRE MESH OPENING CHARTThis wire mesh chart is provided to simplify the process of selecting a "standard" wire cloth specification suitable for your screening application. The most popular wire cloth specifications listed on this page are listed by screen opening (aperture) size, sorted in descending order.

Vibrating Screen Bed Depth Formula
The feed to a vibrating wire mesh screen contains a mixture of material in varying sizes. The oversized material will retard passage of the undersized material, creating a temporary restriction which results in a build-up (bed) of material on the surface of the screen.
Bed depth diminishes as the undersize material passes through the wire mesh screen apertures.
The material bed should not be allowed to reach a depth that prevents the undersize from stratifying before discharge at the wire mesh screen surface end.
Generally, the discharge end bed depth should not exceed four times the size of the wire mesh screen surface aperture when separating 100 lbs. per cubic foot material, or three times for 50 lbs. per cubic foot material.
Aggregate, Ore and Gravel Screening Formula for calculating theoretical discharge end bed depth:
DBD =
______O x C______ 5 x T x
W
= Inches of Bed Depth
DBD = Discharge End Bed Depth
O = Oversize in STPH
C = Cubic Feet Per Ton of Material
5 = Formula Constant
T = Rate of Travel (nominal 75 fpm for inclined screen at slope of 18º to 20º with flow rotation and nominal 45 fpm for horizontal screen)
W = Width of Screening Area in Feet
Wire Cloth Screen Edge Hook Clamping StripsScreens for classifying, sizing, straining, sieving, are typically secured to a vibrating deck by clamping rails that apply tension across the screening surface. The tension is applied through edge treatments on the woven wire cloth screen panel commonly referred to as "hooks" , "hook strips" or "hooking strips". Proper screen tension is crucial for effective screening and longer screen life. Banded edges prevent flattening of hook edges and eliminate mesh pull-out on fine wire mesh or high tension screens.
Plain Hooked Edge
Without Reinforcing, Typically provided on screens of 5/16" and larger wire diameters. Edges are annealed before forming to eliminate cracking and breakage.
Inside Reinforced Formed Edge
This hook strip is utilized for screens 5/16" and larger wire diameters. Edges are annealed before forming to eliminate cracking and breakage.
Reinforced Shroud Banded Edge
Provided as standard on screens up to 1/4" wire diameter. Standard shrouding is 16 gauge with other thickness' available on request.
Double Folded Reinforced Shroud Banded Edge
This treatment eliminates screen pull-out on screens woven of smaller wire diameters. Standard shrouding is 20 gauge with other thickness' available on request.
Double Reinforced Shroud Banded Edge
This treatment also eliminates screen pull-out on finer wire sizes. It includes a internal metal insert for reinforcement. Standard shrouding is 20 gauge with other thickness available on request.
End Tension Reinforced Shroud Banded Edge
Specially reinforced to prevent pull-out under extreme screen tensioning. Also available in Double Reinforced Style.
When ordering screen edge preparations, give vertical height of hook (H) and angle of formed edge (A).
Standard hook length (L) is 1".
Standard hook height (H) is 3/4".
Standard angle is 45° - 65°.
Woven Wire Cloth SelectionThe following information is required to process your inquiry promptly and efficiently: Mesh -or- OpeningThe mesh count (number of openings per linear inch) or the desired opening (clear space between adjacent parallel wires) should be entered in the form.
Wire DiameterThe wire diameter has a direct proportional relationship between strength and the percentage of open area. As the wire diameter increases, strength increases and open area decreases. As the wire diameter decreases, the open area increases and the strength decreases.
Greater strength improves screen life.
Greater open area improves screen throughput. If you require assistance in selecting the wire diameter, please provide detailed information regarding your application in the "Comments" text box.
MaterialThe pull down menu in the material field contains several different types of materials that are most frequently utilized in the production of wire cloth.
For assistance in material selection, provide detailed information regarding the application in the "Comments" section.
Roll LengthThe standard woven wire roll length is 100' although shorter or longer rolls can be provided.
If you prefer, wire cloth can be provided in panels rather than in roll form. Panels may be produced by cutting existing roll stock to the desired length or cut to length during the weaving process.
Please indicate the desired roll or panel length. Any critical tolerances should be specified in the "Comments" text box.
Roll WidthStandard roll widths are 24" 36" 40" 48" and 60". Narrower specifications may be slit directly on the loom or as a secondary operation from existing roll stock.
Edge Condition
Normal raw (slit) edges will be provided unless otherwise specified.When necessary, smooth selvage edges can be provided at extra cost. The most popular selvage is "looped" although brushed, feathered, plastic coated or welded edge treatments are available by order.
QuantityPlease indicate the number of panels (pieces) or rolls required.
If the total quantity is to be delivered in a number of shipments, please specify the amount desired per release and the dates required in the "Comments" text box.

Plain Dutch Weave
Filter Cloth
Plain Dutch Filter Weaves can accommodate high flow rates with a relatively low pressure drop. They are woven with each warp and weft (shute) wire passing over and under one wire. The weft wires are smaller in diameter than the warp wires and are driven up close together, creating a dense filtration weave.
Mesh Counts shown without wire diameters are typically not available from stock.

Twill Dutch Weave Filter Cloth
In a Twill Dutch (Hollander) Weave the weft wires are driven up so tightly that there is always a shute wire above and below the warp wires, creating a weave with the warp wires completely covered. The flow-pass geometry is extremely tortuous, allowing reasonable flow rates while insuring excellent particle size retention.
