home Wedge Wire Screen Panels
Currently, wedge wire screen panels are widely used in the industry, agriculture, construction, brewing, greening and grain screening industries. Then, how important is the wedge wire screen panel in the grain industry?
Wedge wire screen panel plays two important roles in grain industry: drying and screening.
Air continuously passes through the wedge wire screen panel, keeping the grain fresh and drying quickly. By improving ventilation in grain bins, grains can remove moisture quickly and prevent bacterial growth. Therefore, grains are stored in good conditions as seeds, thereby leading to greater grain yield.
When storing grains, impurities such as debris, pebbles, and particles may be mixed in. We can determine the slot size of the wedge wire screen panel according to the size of the grain to screen the impurities out and ensure the cleanliness of the grain.
In addition, perforated plates also meet these requirements for drying and screening. However, we need to consider the differences in product features to determine which product is used. We compare the characteristics of perforated plates and wedge wire screen panels as listed below
| Perforated plate | Wedge wire screen panel |
| Due to the limitation of punching strength, the steel plate cannot be too thick, resulting in poor wear resistance and short service life. | Welding at each intersection makes it can withstand high pressures and heavy loads, leading to excellent wear resistance and long service life. |
| Limited by the mechanical strength of the perforated plate, the hole distance cannot be too small, resulting in the low opening rate of the perforated plate. | Wide range of slot sizes and high open areas. |
| When the grain collides with the perforated plate, the rebound force is small, which makes the grain easy to block the openings. | The unique structure of the wedge wire screen panel can ensure the contact between the grain and the gap, and minimize the clogging of near-sized grains. |
| During the punching process, the perforated plate is subjected to repeated pressure, resulting in the poor flatness of the perforated plate and affects the screening effect. | Has very good smooth filtering surface and high flatness. |
Choosing the right wedge wire screen panel can provide excellent drying and sieving effects for your grains and other crops. If you need any help in selecting a wedge wire screen panel, we will be happy to help you at any time.
