A mobile crusher is a portable crushing and screening system designed to process rocks, ores, or construction waste. Unlike fixed plants, it is mounted on a tracked or wheeled chassis, enabling easy relocation. These systems are used in aggregate production, recycling, and mining.

Working Principle:

  1. Feeding: Large materials are loaded into the feeder via an excavator.

  2. Crushing Stages:

    • Primary Crushing: Jaw crusher or impact crusher reduces material to 100-300 mm.

    • Secondary/Tertiary Crushing: Cone crusher or VSI crushes material to 0-32 mm.

  3. Screening: Vibrating screens classify crushed materials into sand, gravel, etc.

  4. Stockpiling: Conveyors transport sorted materials to storage areas.

Examples of Use:

  1. Quarry Application:

    • A tracked mobile crusher processes granite blocks into 20-40 mm gravel for road construction.

  2. Construction Waste Recycling:

    • A wheeled mobile impact crusher recycles concrete debris into 0-20 mm recycled aggregate.

  3. Urban Projects:

    • A compact mobile crusher processes asphalt waste in tight city spaces for reuse in road surfacing.

Advantages:

  • Mobility: Rapid deployment even on rough terrain.

  • Versatility: Handles diverse materials with interchangeable crushers.

  • Cost Efficiency: Reduces transportation and labor costs.
