A crusher, or fixed crushing plant, is a heavy industrial machine that reduces large stones, rocks, and construction waste into smaller aggregates through mechanical processes. These aggregates are essential in construction materials like concrete, asphalt, and road base.

Functions

  • Breaks down raw rocks from quarries.

  • Recycles demolition waste into usable products.

  • Produces different sizes of crushed stone, sand, and gravel.

  • Prepares ore in mining operations for processing.

How It Works

  1. Feeding: Trucks or loaders dump material into the feed hopper.

  2. Pre-screening: Smaller material bypasses crushers, larger pieces go to the primary crusher.

  3. Primary Crushing: Jaw crushers perform initial size reduction.

  4. Secondary/Tertiary Crushing: Cone or impact crushers further reduce size.

  5. Screening: Vibrating screens sort material into different sizes.

  6. Conveying and Stockpiling: Conveyor belts transport materials to storage.

  7. Dust Suppression: Water sprays or filters reduce airborne dust.

Applications

  • Aggregate quarries

  • Concrete and asphalt batching plants

  • Infrastructure construction (roads, airports)

  • Dams, harbors, bridges

  • Mining and mineral processing

  • Industrial recycling centers

2. MOBILE CRUSHER

Definition

A mobile crusher is a portable crushing and screening system mounted on tracks or wheels, designed to be quickly moved between locations. It combines crushers, screens, and conveyors into one compact unit.

Functions

  • Performs on-site crushing and screening.

  • Processes demolition material directly at the source.

  • Eliminates the need for transportation to fixed facilities.

  • Flexible and efficient for short-term or remote projects.

How It Works

  1. Deployment: The unit is towed or self-driven to the job site.

  2. Feeding: Raw material is loaded into the machine.

  3. Crushing: Jaw, impact, or cone crushers reduce the material size.

  4. Screening: Vibrating screens separate output by size.

  5. Conveying: Conveyors move materials to exits or piles.

  6. Power Supply: Runs on diesel engines or electric power.

Applications

  • Temporary construction sites

  • Urban demolition and recycling

  • Mining in remote areas

  • Maintenance of rural roads

  • Infrastructure in difficult terrain
