How to choose vibrating screen panels ?

The application of vibrating screens is very common in sand and gravel processing systems, and the vibrating screen panels as its main component is the key to quality and productivity of finished products. This paper will focus on the four types of screen panels in sand screening process, such as polyurethane screen, steel screen, steel screen and square steel screen, which will produce the impact on aggregate quality, service life and economic cost, in order to play a certain role in the selection of screen panel.

Effect of four screen panels on aggregate quality

Due to the different materials of four screens, it will directly affect the opening form and opening ratio of the screen during use, thus affecting the quality of finished sand.

1. Polyurethane screen panel

Due to the low strength and relatively high toughness of polyurethane, the width and thickness of scree panels are required to resist the damage caused by the falling of aggregate from the belt conveyor. In the case where the size of screen panel is constant, it is inevitable to reduce the opening ratio of the screen, which will reduce the screen permeability of vibration screen. So the polyurethane screen panel are mainly used in dewatering screens.

2. Steel screen panel

The steel steel mesh has high strength, strong anti-aggregate impact, and smooth and flat surface, which can reduce the blockage during movement, and has a good opening ratio under the condition of ensuring the strength of screen. Therefore, the screen permeability can be greatly improved.

3. Punched Steel Plate

Such a screen is usually used in the form of round or rectangular openings. Since the hole is directly punched on steel plate, so the entire sieve surface is relatively smooth in use, which is favorable for the sliding of the aggregate. However, since the aggregate is more irregular polygons, the probability of the round hole jam is greater than the square opening.

4. Square steel screen

The square steel screen has better strength, opening ratio and the screen permeability of the screen can be effectively ensured.

Comparison of the service life of four screens

Due to the different rock property and production conditions, there will be some differences in the service life of screen. In order to better compare the service life of four different screens, the four vibration screen panels will be compared under a certain conditions.

1. Polyurethane screen has good toughness and strong wear resistance. However, its service life is not ideal in actual use. It was observed that it was caused by the impact of aggregate falling from belt conveyor during use, which caused a strong impact on the screen and caused screen mesh to be easily broken. However, the impact of the aggregate on screen can be reduced by improving the blanking, thereby improving the effective service life of the screen.

2. The steel screen is made of 16Mn material, which will improve the wear resistance. However, in order to ensure the opening ratio, the connecting plate between the hole and hole will be thinner. So the impact resistance is not very good and will affect the final service life of the steel screen. In addition, the steel screen is often fastened to the screen and the mesh support bolts during use, otherwise the relative movement between the steel screen and the screen support will be caused, and the service life will be greatly reduced.

3. The difference between strength and toughness of the steel mesh screen and the square steel screen is not very large, so the impact of two against aggregate is not very different. However, due to the different materials used in the two, the square steel screen is better than the steel screen in terms of wear resistance.

Comparison of four screen operating costs

1. The main material cost of polyurethane screen is high. However, the advantage is that there is no necessary production cost, and the labor cost is also low. It is not necessary to use other auxiliary tools for installation, and the installation can be completed only by manual.

2. The cost of the main material of steel mesh and square steel mesh is lower, but the production cost is larger. It takes a lot of manpower and time to make it. The use of auxiliary tools during the installation process will also incur a certain cost.

3. The punched steel plate is cut directly on the steel plate. Compared with the steel and square steel screen, the strength is small, but it is larger than the polyurethane screen. It can also be completed by means of auxiliary tools.

It should also be noted that in the use of these four kinds of screens, the polyurethane screen should be composed of small pieces as much as possible, and can be replaced according to the wear condition, otherwise a large piece of screen will be replaced due to partial damage.

The other three types of screens can be repaired and welded in time because the use of the structural parts. However, it should be noted that the screen at the blanking point of the screen should not be connected with the lower screen. Because the screen at the blanking site is damaged by the aggregate, and can be replaced small pieces at any time.

Wire Mesh Dewatering Screen Specifications: What Is Right for Me?

Dewatering is a critical step in aggregate processing. It calls for the use of accurate screening equipment to remove water from freshly washed or mined sediment while retaining the material to form a filter cake.

Woven wire mesh dewatering screens are often used as they allow for offer a desirable balance of durability and throughput. But just as with any screening media, their performance is dedicated to selecting the right set of specifications.

Odds are you are probably looking into what you need to implement dewatering screens into your process and are left questioning what specifications are right for you.

W.S. Tyler has been a prominent supplier of woven wire mesh for over 150, helping customers across dozens of industries implement the versatile material along the way. We strive to learn their operation and pain points inside and out in an effort to point them toward solutions that work and drive profits.

And with that, this article was written to establish the mesh specifications you need to keep in mind when designing a woven wire mesh dewatering screen. It will cover:

How to select specifications that work

What Is a Woven Wire Mesh Dewatering Screen?

Woven wire mesh is a metallic screening cloth comprised of individual wires that become interwoven after a centuries-old weaving process. A dewatering screen is a screening device designed to perform efficient solid-liquid separation.

When using woven wire mesh as the designated screening media, dewatering screens have the ability to screen particles within a range of 4 mesh to 325 mesh. To that end, they are often employed to drain the water that is used to wash or mine various forms of sediments, such as sand or coal.

What Specifications Should I Be Mindful of When Designing a Woven Wire Mesh Dewatering Screen?

There are three primary specifications that you should be taking into consideration when designing your wire mesh dewatering screens. These specifications are weave type, panel dimension, and hook type.

Weave Type

The wire mesh layers in a W.S. Tyler dewatering screen can be woven following one of three weave patterns: square mesh, TY-ROD, and TON-CAP. Each pattern was designed to deliver a specific set of benefits that will help you create a tailored solution.

Square Mesh

Square mesh is a standard weave type that uses a simple over-under weave style. It is known for its tight tolerances and precise mesh openings.

With this over-under style, many variations of the weave type can be achieved. For example, two warp wires can go over the single weft wire. This can help enhance the rigidity of the weave while also controlling the size of the mesh openings.

TY-ROD

TY-ROD is a weave type designed to minimize blinding. This is accomplished by weaving the wires to feature slotted openings larger than those of the TON-CAP weave.

These slotted openings can be woven to lengths up to 2”.

Not only do these elongated slotted openings prevent blinding, they work to deliver superior throughput. Furthermore, the characteristics of TY-ROD can minimize cleaning time.

TON-CAP

TON-CAP is a weave type that, like TY-ROD, is woven to feature slotted openings. This unique weave allows you to implement performance similar to a square mesh while using a much thicker wire.

To achieve such performance, every other weft wire must be removed.

Standing for tonnage capacity, the thick wires of TON-CAP make it particularly useful when applied to high-capacity applications. This is because, with thicker wires, you can increase the throughput of material without the risk of premature wear.

Panel Dimension

Knowing what panel dimensions your equipment is designed to hold is key to optimal dewatering. Having a panel too large will cause slack throughout the panel, resulting in inconsistent screening and premature wear.

A standard woven wire mesh dewatering screen has a dimension of 48.5” (inside/outside the hooks) x 5’. Each screen will typically come in 5-foot increments.

While this is the standard dimension, they can be exceeded upon request.

Hook Type

The hooks of a woven wire mesh dewatering screen are multifunctional. They work to secure the screen in the vibrating screen machine while also ensuring the screen is drum-tight.

These hooks will often be constructed from a galvanized steel, with plastic inserts to prevent dissimilar metal corrosion. You do have the option to request other alloys, such as stainless steel, but this will increase the cost and lead time associated with the screen.

How Do I Pick the Right Dewatering Screen Specification?

For the most part, the specifications you should be using to design your dewatering screens should be established within your organization. But if you are confused by the set specifications or your organization has not yet set these specific standards, a reliable wire mesh supplier will be able to work with you to determine what is right for you.

Knowing the particle size range of the material that should be screened and retained is critical. Providing this information will better equip the mesh supplier to calculate the mesh opening size, weave type, and layer configuration you need to reach your goals.

Providing the make and model of the machine will also enable the supplier to spec out the dimensions of the dewatering screen panel. This will ensure the measurements of the screen with the hooked attached accommodate the particular vibrating screen machine you are working with.

NOTE: The length measurements of a dewatering screen can either reflect measurements taken within the clamps or outside the hooks. These measurements are key to keeping the mesh drum tight once installed in the machine.

Understand How Woven Wire Dewatering Screens Compares To Similar Solutions

Picking the right hook type, weave type, and dimension combination is critical to the success of any woven wire dewatering screen. Naturally, the combination that is right for you is dependent on the particle size range of your material and the vibrating screen machine you are using.

By now, you should have a general understanding of the capabilities of woven wire dewatering screens. But in order to feel confident in your investment, you must compare and contrast these capabilities to other dewatering screen solutions, such as flex-mat.

For over 150 years, W.S. Tyler has helped customers implement wire mesh screening solutions that deliver peace of mind. We strive to learn your process inside and out in an effort to resolve any doubts you may have about woven wire mesh.
