A portable mineral crushing and screening plant is a mobile system mounted on tracks or wheels, designed to process ores or aggregates directly at mining or remote sites. Unlike fixed plants, it requires no permanent installation and integrates primary crushers, secondary crushers, vibrating screens, feeders, and conveyors.

Purpose

  • Ore Processing: Prepares gold, copper, or iron ores for further enrichment by reducing their size.

  • Aggregate Production: Generates sand, gravel, or crushed stone for construction.

  • Waste Recycling: Converts mining waste or demolition debris into reusable materials.

  • Operational Flexibility: Reduces logistics costs and adapts to dynamic project needs.

How Does It Work?

  1. Transportation & Deployment: The plant is moved to the site via truck or self-propelled mechanism and stabilized using hydraulic legs or tracks.

  2. Feeding: Raw ore or material is loaded into the hopper using an excavator or loader.

  3. Crushing Stages:

    • Primary Crushing (Jaw Crusher): Reduces large ore chunks (~1 meter) to 10-20 cm.

    • Secondary Crushing (Cone/Impact Crusher): Further crushes material to 2-5 cm.

    • Tertiary Crushing (Fine Crusher): Achieves final sizes (0.5-2 cm) for specific applications.

  4. Screening: Vibrating screens classify materials into sizes (e.g., 0-5 mm, 5-15 mm).

  5. Storage/Transport: Sorted materials are conveyed to stockpiles or loaded onto trucks.

Applications

  • Open-Pit Mining: Processing gold, copper, or coal ores.

  • Quarry Operations: Producing aggregates for infrastructure projects.

  • Industrial Recycling: Treating slag, mining waste, or construction debris.

  • Remote Sites: Material production for energy pipelines or oil fields.

  • Environmental Rehabilitation: Recycling post-disaster rubble.
