If you're choosing a wire mesh screen for a vibrator or other type of industrial equipment, you have several different screen options to choose from, and the variety can get overwhelming. To ensure you select the right screen for your needs, there are a few elements you should keep in mind. Here is what you need to consider.
1. Deck Compatibility
Every piece of equipment that works with a mesh strainer features a deck which is the frame that holds the screen and eventually hosts the materials you are sifting through your screen.
You need to ensure that you choose a screen that is compatible with your deck. Your machine's instruction manual should have advice on whether you need hardware cloth, a modular screen, non-flexible mesh, or another type of screen.
2. Attachment Mechanism
In addition to choosing a screen that is compatible with your equipment, you also need a screen that attaches to your equipment with sturdy and convenient-to-use attachments.
One popular option is metal fasteners such as tension bolts or spring clasps. Alternatively, you may prefer hook straps which are rigid metal edges that run from the edge of the screen around a lip on the deck. Finally, some pre-tensioned screens simpy use epoxy to attach the screen to tubing on the deck frame.
3. Right Screening Capabilities
While making your choice, you need to ensure that you find the right screening capabilities for the job. In particular, you need to think about the diameter of the wires, the opening sizes, and the weaves.
Your wire thickness needs to be able to support the weight of the items you are sorting, but the openings and weave have to allow particles below a certain size to filter out.
As you use certain types of screens, some of the mesh particles may come off the screen. This is completely normal with many applications, and to deal with this issue, some people choose metal screens with magnetic components.
Then, when you run the screened material through magnetic separators, the magnets attract and remove the magnetic components. However, you also have to balance this function with the strength, durability, flexibility, and other features of the metal.
5. Type of Metal
Finally, you need to think about the type of metal. Different metals have different tensile strengths and various types of flexibility. Some metals may not work well with certain types of materials. They may also have different life spans. Consider these elements while choosing the metal for your screen.
