SZ-450D

SZ-450D Mobile Heavy Duty Screening Plant

Heavy-duty mobile screening

The SZ-450D is a crawler-mounted heavy-duty scalping screen with 200–500 t/h capacity. Its 2-deck screen (5150×1550mm) separates material into up to three size fractions. The max feed size is 500 mm, making it suited for large, coarse materials. Includes a chain plate feeder and three discharge conveyors. Diesel and electric dual power are available.

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.

SZ-450D Mobile Heavy-Duty Scalper brings together high-volume screening, three-size separation in a single pass, and track mobility, making it ideal for demanding applications in mining, aggregates, recycling, and industrial processing. With processing rates up to 200–500 tph, onboard conveyors, and self-powered operation, it offers fast setup, flexible deployment, and significant savings in time and logistics.

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.
