Working Principle
SZ‑450D Mobile Heavy Duty Screening Plant is a track‑mounted heavy‑duty scalping screen designed for large, rugged materials. Its core operation includes:
-
Vibrating screen box with multiple decks: Material is fed via conveyor into a robust screen housing equipped with high‑frequency vibrators. The vibration shakes particles through layered meshes, separating them by size into three distinct fractions.
-
Independent discharge conveyors: Three dedicated belt conveyors separately carry off the screened sizes, maintaining clear stockpiles and minimizing material mixing.
-
Crawler mobility with self-contained power: Mounted on a track system, the unit can traverse rough terrain and be driven directly into work zones. It features both diesel and electric power systems, allowing on-site operation without external infrastructure.
Application
- Mining and Ore Pre‑Screening
Ideal for removing oversized material before crushing stages, improving crusher life and throughput efficiency. - Quarries and Aggregate Processing
Efficiently classifies rock, gravel, and crushed stone, producing multiple aggregate sizes on-site and reducing logistics costs. - Construction & Demolition Recycling
Sorts mixed debris such as concrete, bricks, and asphalt into reusable fractions, promoting circular material usage. - Coal and Industrial Waste Segregation
Handles heavy, abrasive materials like coal and industrial by-products, separating them cleanly by size for further processing or disposal. - Complex Terrain Worksites
Its tracked chassis makes it suitable for mountainous regions, narrow sites, or urban demolition zones—no need for groundwork or external support.
