What Are Polyurethane Tension Screens

Definition and Structure

You may ask what polyurethane tension screens are. These screens are made in one piece. They replace old wire or plate panels. The mat is molded in big sections. It covers more space and handles more stuff. Hooks are on the edges. You can clamp them to the vibrating deck. This makes it easy to change panels fast. Your machine keeps working without long stops.

Reinforced Metallic Cables

Each urethane screen panel has strong metal cables inside. These cables, rods, or bars make the screen stronger. When you tighten the screen, the cables spread the tension. The screen stays in place, even if the machine shakes a lot. The metal inside takes the strain and heavy loads. You can use these screens for hard jobs. They work for sorting fine materials or big rocks.

High-Strength Polyurethane

The main part of the screen uses strong polyurethane. This material is tough and bends without breaking. Polyurethane tension screens have special additives. These help the screen bend, last longer, and resist wear. The screen keeps its shape and strength, even if it gets hot or cold. You can trust these panels in any condition.

Tip: If you install and take care of your urethane screen panels, they last longer and save you money.

How They Work in Screening Systems

When you use polyurethane tension screens, your machines work better and faster. These screens fit into your process easily and help you do more work.

Tensioning and Installation

Pre-Tensioned Design

You do not need to change your machines to use polyurethane tension screens. The pre-tensioned design lets you put them in like old metal mesh panels. You save time because you use the same clamps and fixings. Urethane screen panels come ready to use, so you do not spend hours setting up. You just hook them onto your vibrating screens and tighten them.

Here is why installation is simple:

  • The pre-tensioned system means you do not need special tools.
  • You can change panels fast, so you stop less.
  • Urethane screen panels fit right into your old frames.

You get more work done because you do not stop for repairs or new parts as much.

Frame Compatibility

Polyurethane screen panels work with most screening machines. You do not have to buy new equipment. Urethane screen panels use the same hooks and clamps as metal mesh. You can put them on vibrating screens, scalping decks, or dewatering setups. The panels stay tight, even if your machine shakes a lot.

If you want the best results, follow these steps:

  1. Use a laser rangefinder to check the panel size. Make sure the size is within ±1.5mm and the flatness is less than 0.3mm per square meter.
  2. Fix the center first, then work out along a 45° angle. This keeps the panel flat.
  3. Set the hydraulic tension between 0.8 and 1.2 MPa. Tighten the panel in three steps: 60% at first, 80% after 24 hours, and 100% at the end.
  4. Run a vibration test with no load. The amplitude difference should be less than 15% of the design value.
  5. Check tension every shift, measure wear every week, and tighten connectors every month.

Tip: If you follow these steps, your polyurethane tension screens will last longer and work better.

Screening Process

Vibrational Energy Absorption

Polyurethane tension screens handle vibration very well. Urethane screen panels are stretchy, so they soak up shaking. When your vibrating screens run, the panels bend and bounce. This makes extra shaking that helps knock off stuck material. You get less clogging and more material moving through.

Here is why this helps you:

  • Polyurethane screen panels make less noise, so your work area is quieter.
  • Urethane screen panels stop material from sticking, so you clean less.
  • The panels keep their shape, even after lots of shaking.

You see better results and smoother work.

Particle Separation Efficiency

You want your screens to sort things well. Polyurethane tension screens do this job fast and clean. Urethane screen panels help separate small and big pieces. You get sharp sorting and better filtering.

Let’s see how polyurethane tension screens last compared to others:

MaterialAverage Lifespan (Months)
Polyurethane Screen Mesh12-18
Rubber Screens3-4
Steel Woven Mesh1.5-2.5

You can see polyurethane screen panels last much longer than rubber or steel mesh. Urethane screen panels keep working, so you do not need to replace them as often. You get more work time and fewer problems.

Note: If you use polyurethane tension screens, you work faster and sort better. Your machines run smoother, and you spend less on fixing them.

Polyurethane tension screens give you strong results, high efficiency, and easy setup. Urethane screen panels fit your machines, soak up vibration, and sort particles well. You get the best results in screening and separation every time.

Screen Media Comparison

Polyurethane vs. Metal Mesh

You may wonder how polyurethane screen panels compare to metal mesh screens. Polyurethane screen panels last much longer than metal mesh. They can work 8-10 times longer before wearing out. Urethane screen panels keep their shape, so sorting stays accurate. Metal mesh screens wear out fast and can bend. When they bend, sorting is not as good.

Here is a table to help you see the differences:

FeaturePolyurethane Tension ScreensMetal Mesh Screens
Lifespan8-10 times longer than ordinary metal screensShorter lifespan due to wear and tear
Screening EfficiencyHigh efficiency with self-cleaning propertiesProne to clogging and lower efficiency
Screening AccuracyUniform pore size with small toleranceDeformation leads to size deviations
ApplicabilitySuitable for various materials, wet and dryLimited by material type and conditions

Polyurethane screen panels are easier to take care of. You only need to check the tension often. You can use special meters to make sure they are tight. Metal mesh screens need more checks because damage is hard to see. You spend less time fixing polyurethane screen panels and more time working.

Tip: If you want less downtime and better results, try modular polyurethane screen panels for your next modular replacement.

Polyurethane vs. Rubber Screens

Let’s see how polyurethane screen panels do against rubber screens. Urethane screen panels are better for tough jobs. Polyurethane handles rough use and lasts longer. Rubber screens are good for big hits but wear out faster in harsh places. Urethane screen panels keep their holes the right size, so sorting is sharp. Rubber screens can stretch and lose shape, which makes sorting less accurate.

Look at this table to compare them:

MaterialAdvantagesDisadvantages
Rubber– Great at handling big impacts– Wears out faster in rough jobs
– Costs less at first– Does not last as long as polyurethane
– Bends to fit more material in coarse sizing
Polyurethane– Lasts longer in rough jobs– Costs more at first
– Keeps holes the right size– Not always best for very big pieces
– Works well in wet jobs and cleans itself
– Panels last longer in rough jobs

You get more work done with modular polyurethane screen panels. Urethane screen panels last longer and need fewer modular replacements. You save money over time, even if you pay more at first.

Installation & Maintenance

Setup Guidelines

Tensioning Requirements

You want your polyurethane tension screens to last long. Start with a flat frame. Make sure it is not off by more than 3 mm per square meter. Use laser tools to check the tension. Try to keep the tension even, within 2 percent. Tighten bolts a little at a time, about 25 percent each step. This helps the screen settle flat. After two days, check and tighten the panels again. This is important because the screen can move a bit after use. Check the tension and bolts every 250 hours. These steps help your screens last up to 30 percent longer.

Tip: If you follow these steps, you can cut edge wear by 60 percent and stop early breaks.

Common Challenges

You might have some problems when you install the screens. If the tension is wrong, the screen can break early. Always check the tension before you start the machine. If you see big pieces stuck in the screen (pegging) or sticky stuff blocking holes (blinding), try high-vibration screen panels. These panels help shake loose the stuck material. If you still have trouble, check for broken parts or mistakes in how you set up the screen. You can also use different screen types together to get better results for each job.

Maintenance Tips

Cleaning & Inspection

You want your polyurethane screens to work well every day. Cleaning and checking them is important. Here is a simple table to help you remember what to do:

Routine TypeDescription
Daily CleaningClean the screens after each shutdown. Take off debris to keep things balanced.
Regular InspectionsLook for signs of wear like thin spots, layers coming apart, or dents.

If you clean and check your screens often, you will find problems early and avoid big repairs.

Repair & Replacement

When you see damage, fix it right away. Replace panels with cracks, holes, or lots of wear. If you see small problems, you can sometimes fix them with patch kits. Always use the right tools and follow the maker’s instructions. Doing repairs on time helps your polyurethane screens last longer.

Note: Regular care helps you avoid costly stops and keeps your screening system working well.

Equipment Compatibility

Before you put in polyurethane tension screens, check if they fit your machines. Make sure the screens are the right size and shape for your equipment. Polyurethane screens must handle the shaking and movement of your system. Sometimes, you may need to make small changes to your setup for the best results. If you do this, your screens will last longer and work better.

If you take time to check if the screens fit, you will get the most out of your polyurethane screens.

Choosing the Right Screen

Aperture & Size Selection

Picking the right screen starts with the aperture and size. You want your polyurethane screen to match your job. The holes, or apertures, decide what size material passes through. If you choose the wrong size, you might get too much waste or not enough product. Always check your installation structure. Larger apertures need bolt-type fixing. This keeps the screen from coming loose.

Think about your feeding design, too. If you drop material from too high, you can damage the screen. Try to keep the feeding height under 400mm. This helps your polyurethane screen last longer. Regularly tighten the bolts. Loose screens can hit the support bars and break.

Here’s a quick table to help you remember what to check:

FactorDescription
Installation StructureMatch aperture size; large holes need bolt-type fixing
Material TypePolyether for wet jobs, polyester for dry jobs
MaintenanceTighten bolts often to stop damage
Feeding DesignKeep feed height under 400mm to protect the screen

Material Grades

You have choices when it comes to material grades. Polyurethane screens come in different types for different jobs. If you work with wet material, pick polyether. For dry jobs, polyester works better. The right grade helps your screen last longer and work better.

Some screens need to be soft to handle sticky material. Others need to be hard for sharp rocks. You can talk to your supplier about what grade fits your job. The right choice means less downtime and more product.

Tip: Always match the material grade to your work environment. This keeps your polyurethane screen working at its best.

Customization Options

Every job is different. You might need a special screen size or shape. Polyurethane screens can be customized for your needs. You can pick the aperture size and shape. You can choose the panel thickness, from 5 mm up to 50 mm. This lets you use the screen in many places.

You can also pick between modular or tensioned designs. Some jobs need a harder screen, while others need a softer one. You can even get special sizes, like 305305mm or 610610mm. If you need something unique, just ask for a custom size.

Here’s a table of what you can customize:

Customization AspectDetails
Aperture sizes and shapesTailored for your job
Panel thickness and sizeFrom 5 mm to 50 mm, many external sizes available
Modular or tensioned designPick what fits your machine
Material hardnessChoose soft or hard for your application

With all these options, you can make sure your polyurethane screen fits your machine and your job. You get better results and save money in the long run.

Environmental Factors

When you pick a screen, think about where it will be used. Polyurethane tension screens can do hard jobs, but the environment can change how they work. There are some things you need to watch out for.

Temperature is important. If your work area gets very hot, polyurethane can get soft. This makes the screen weaker and it might stretch or lose its shape. If it gets very cold, the screen can turn stiff. When this happens, it could crack if you press on it too much. You want your screens to stay strong, so always check the temperature in your plant.

Chemicals are another thing to think about. Polyurethane does well with many chemicals. Oils, acids, and solvents usually do not hurt it. You can use these screens where other materials would break down. If you use strong chemicals, polyurethane is a smart choice.

Water and pH levels can also change how your screens work. Polyurethane does not like too much water, especially if the pH goes up and down a lot. Over time, water can break down the screen in a process called hydrolysis. This makes the screen weaker and less bendy. If your job uses lots of water or has changing pH, check your screens often.

Here is a short list of how the environment affects polyurethane tension screens:

  • Polyurethane stays strong and keeps its shape under high pressure.
  • It fights off damage from most chemicals, like oils, acids, and solvents.
  • High heat can make polyurethane soft, but cold can make it stiff and easy to crack.
  • Water and changing pH can cause hydrolysis, which makes the screen weaker over time.

You can use this table to help you decide if polyurethane is good for your job:

Environmental FactorPolyurethane PerformanceWhat You Should Do
High PressureStays strong and stableUse for heavy-duty screening
Chemical ExposureResists most chemicalsGood for chemical plants
Extreme HeatMay soften and lose shapeMonitor temperature, use additives
Extreme ColdCan become rigid and crackAvoid sudden impacts
Water & pH ChangesMay weaken from hydrolysisInspect screens regularly

Tip: If you work in a place with changing temperatures or lots of chemicals, check your polyurethane screens often. Checking them helps you find problems early and keeps your system working well.

You want your screens to last and work right. By thinking about these things, you can pick the best polyurethane tension screen for your job. You get better results and spend less money fixing things.
