A vibrating screen deck is the critical component of a product screening system that provides the separation surface. It consists of a frame supporting screening media (such as wire mesh, polyurethane panels, or perforated plates) that vibrates to stratify and separate materials by particle size as they move across the surface. The deck is mounted on a vibrating screen frame and subjected to high-frequency vibrations, typically circular, linear, or elliptical motion. These vibrations cause materials to stratify, with finer particles passing through the screening media openings while larger particles travel across the surface to the discharge end. The deck's performance is influenced by several parameters, including screen area (1.5–10 m²), mesh size (0.5–100 mm, per ISO 9044), open area (30–60%), vibration amplitude (2–8 mm), vibration frequency (700–1200 rpm), processing capacity (10–500 t/h per m²), separation efficiency (85–95%), operating temperature (-20–80 °C), material grade (Q235A/304/316, per GB/T 700 and ASTM A240), screen cloth thickness (1–10 mm), and weight (500–5000 kg per deck). Materials commonly used include high-carbon steel wire, stainless steel, polyurethane, and rubber. These values are reference ranges and must be verified for the specific model and application. The deck is a component, not a standalone machine, and its selection depends on material characteristics, desired cut point, and throughput requirements. Proper installation and maintenance are essential for consistent performance. Always confirm model-specific values and standards with the legal manufacturer or supplier.

These vibrations cause materials to stratify, with finer particles passing through the screening media openings while larger particles travel across the surface to the discharge end. The motion parameters, such as amplitude and frequency, are set to match the material properties and desired separation efficiency.
