The screening process using perforated plates is complex, and if they are solely used for material screening, issues with screening quality may arise. These problems are influenced by several factors, and without correctly analyzing or identifying the relevant factors, it can be difficult to resolve common screening issues.
In the screening process, the physical properties of the material, such as particle size distribution and moisture content, have a significant impact. These factors can affect the efficiency of the perforated plate in screening operations. Additionally, the properties of the screening surface and structural parameters also influence the quality of the perforated plate's performance. A machine screen with high production capacity is often preferred in industrial applications. To address these challenges, we developed a new type of perforated plate—fish scale perforated plate. It can alter the movement pattern of materials, changing the flow from a laminar motion close to the screen surface to a more pulsating motion. This product is primarily used as a sample-screening plate in feed mills.
Typical perforated plates are flat or smooth, with the edges of the holes being clean, and the axis of the holes running parallel to the material’s flow direction. In practice, ordinary perforated plates can lead to issues such as slow discharge, low output, high power consumption, and excessive pulverization.
Since traditional perforated plates do not meet user demands, we use fish scale perforated plates to improve performance. The edges of the fish scale holes are raised and sharp, and the plates are installed in the opposite direction of the hammer blade rotation. This design reduces the distance between the hammer and screen, thins the material flow layer, and reduces the resistance to material passing through the screen. Simultaneously, it increases the resistance to material movement, slowing the flow rate and allowing the material to pass more efficiently through the perforated plate’s holes for better screening.
Advantages of Fish Scale Perforated Plates:
Improved Material Movement: Fish scale perforated plates change the material movement from a laminar flow to a pulsating motion, improving screening efficiency.
Reduced Material Resistance: The fish scale design reduces the thickness of the material flow layer, decreasing the resistance when the material passes through the perforated plate, speeding up the screening process.
Enhanced Screening Effectiveness: By installing the plate opposite to the direction of the hammer's rotation, the fish scale perforated plate increases the resistance to material movement, slowing the material flow and ensuring better screening through the holes.
Fish scale perforated plates are mainly used as sample screening plates in feed mills. They effectively address issues such as slow discharge and high power consumption in traditional screening plates, and are widely used in the screening field. By adopting fish scale perforated plates, the screening efficiency is improved, and energy consumption during production is optimized, making them a more efficient tool for screening applications.
