A crusher is a machine designed to reduce large rocks, stones, or raw materials into smaller aggregates (gravel, sand, crushed stone) for construction and industrial use. It comprises primary, secondary, and tertiary crushers, screens, conveyors, and hoppers, and can be stationary or mobile.

Purpose

  • Size Reduction: Rocks are crushed via jaw, impact, or cone crushers.

  • Classification: Vibrating screens sort aggregates by size.

  • Aggregate Production: Generates materials for concrete, asphalt, and road bases.

How Does It Work?

  1. Feeding: Large rocks are loaded into the crusher via a hopper or excavator.

  2. Primary Crushing: Jaw or impact crushers break materials into coarse fragments.

  3. Secondary/Tertiary Crushing: Cone crushers further reduce size.

  4. Screening: Screens separate aggregates into specific sizes.

  5. Storage/Transport: Final products are stored or transported to sites.

Applications

  • Construction: Road, bridge, and building foundations.

  • Mining: Processing quarried stones.

  • Recycling: Crushing concrete or asphalt waste.

  • Industrial Plants: Cement and asphalt production.

What is a Mobile Crusher?

A mobile crusher is a portable crushing plant mounted on wheels or tracks, enabling on-site processing without fixed installation.

Purpose

  • On-Site Crushing: Processes materials directly at remote or temporary sites.

  • Cost Efficiency: Reduces transport costs and material handling.

  • Versatility: Customizable with jaw, impact, or cone crushers.

How Does It Work?

  1. Mobility: Transported via truck or self-propelled system.

  2. Quick Setup: Operational within 30 minutes using hydraulic systems.

  3. Crushing & Screening: Performs the same functions as stationary plants.

  4. Direct Loading: Aggregates are loaded onto trucks immediately.

Applications

  • Urban Construction: Limited-space projects like city infrastructure.

  • Temporary Sites: Roadwork or disaster debris management.

  • Remote Mining: Processing materials in rugged terrains.
