Comparison of Tuffdeck WS85 panel type and metal screen hook type
Tuffdeck screen is made of polyurethane. It has longer service life than normal metal screens. The below is the comparison with conventional metal screen hook type. Here you can find more details on Tuffdeck.
| Items | Metal Screen Hook Type (Conventional) | Tuffdeck Panel Type |
|---|---|---|
| Size W×L | Screen width ×1200mm | 300mm×1200mm |
| Material | Metal (hard steel wire, SUS304) | Polyurethane with great abrasion resistance |
| Service life | Normal | 3-10 times longer than metal screens |
| Noise | Having big noise, such as when sand and gravel clashing on screens and when steel wires rubbing each other | Having little noise due to the elasticity of polyurethane |
| Structure | Using crimping bars from two sides to tighten the screen | Screen panels are to be inserted into to form a whole screen |
| Running cost | When a screen is partially worn or broken, it needs to be completely changed as a whole, which is very uneconomic. | Only the worn parts need replacing. Because screen panels can be used in rotation, the screen service life can be expended. |
| Screen replacement and maintenance cost | The screen can be removed after the center bolts and crimping bars are removed. After the screen is set up, one needs to install all the parts again thus it costs some labor (sometimes gas is used to prevent bolts from being worn or rotted). As the equipment stops running for a while, productivity is reduce accordingly. |
When removing a screen panel, one can use a screwdriver to lift up a corner of the panel. This is a very easy job. When installing a screen panel, one can use a hammer to help to insert the panel. Due to the simplicity of both screen installation and removal, it is possible for the equipment to get back to work in a very short time. |
| Related parts for screen replacement | Center fixture bolts, rubber plates, crimping bars, sets of bolts and screws, supporting cushion rubber, and gas | Polyurethane side protectors |
| Screening efficiency | Crowns are used to tighten the screen, however, stones can leak from the low positions (such as two edges and the center), thus screening is not efficient. Metal screens are made by cross-weaving wires thus the screen top is not even, easy to cause clogging. | It is unnecessary for panel type screens to be tightened, thus the screen top is even and flat. Stones are distributed equally. Taper openings are not easy to be clogged. |
| Granularity adjustment | As the screen is installed as a whole, only one opening size can be set up. | As the screen is installed by putting many panels together, different opening sizes can be set up. |
| Stock management | Screens are big and heavy, so they take quite a lot of stock space. And transporting them also consumes a lot of labor. | As one piece of panel is small and light, they can be placed in piles on the shelf or around the screen machine. |
