A crusher is a machine used to reduce large rocks, minerals, or construction debris into smaller, manageable particles, commonly used in mining, construction, and recycling sectors.

  • Purpose:
    It breaks down hard materials like stones and ores into smaller pieces suitable for further processing or construction.

  • How it works:
    The raw material enters the feeding section and is pressed or struck between fixed and moving crushing surfaces, such as jaws, cones, or rotors. It’s then separated by screens based on size.

  • Applications:

    • Mining and quarries

    • Infrastructure and road projects

    • Aggregate production

    • Cement plants

    • Construction waste recycling

What Is a Mobile Crusher?

A mobile crusher is a transportable crushing plant mounted on a wheeled or tracked chassis.

  • Purpose:
    Used in temporary or remote locations to process material on-site, saving on transport and setup costs.

  • How it works:
    All crushing and screening units are mounted on a single mobile platform. It's powered by diesel or generator systems, set up quickly, and easily relocated.

  • Applications:

    • Construction sites

    • Demolition projects

    • Short-term mining operations

    • On-site recycling tasks

What Is a Stationary Crusher?

A stationary crusher is a fixed crushing system installed permanently at a specific site for large-scale, long-term operations.

  • Purpose:
    Handles high volumes with continuous efficiency in industrial material processing.

  • How it works:
    Comprises feeders, crushers, vibrating screens, conveyors, and automation systems on a fixed steel structure.

  • Applications:

    • Mining companies

    • Cement and aggregate plants

    • Permanent material production facilities

Differences Between Stationary and Mobile Crushers

  • Mobility: Stationary is fixed; mobile can be moved.

  • Installation: Stationary needs longer setup time; mobile is quick to deploy.

  • Investment: Stationary has high setup costs; mobile is more economical.

  • Capacity: Stationary has greater output capacity.

  • Usage: Stationary for continuous use; mobile for project-based work.

What Is a Vertical Shaft Impact Crusher (VSI)?

A vertical shaft impact crusher (VSI) is a high-speed rotor crusher used for fine crushing and shaping of hard materials.

  • Purpose:
    Produces high-quality artificial sand and aggregates with excellent particle shape.

  • How it works:
    The material drops into the center of a spinning rotor. It is flung outward and hits static anvils or rock-lined walls, breaking into finer pieces through impact.

  • Applications:

    • Sand manufacturing

    • Aggregate shaping for concrete and asphalt

    • Quartz, basalt, dolomite, glass crushing

    • Marble and granite dust production
